There is a problem with some of the reasoning in this though I will agree with the premise that the wall is a waste of money.
The idea that illegals come here only for jobs is incorrect as well as doing jobs that Americans won't do. Illegals are coming here for welfare because the Department of Health and Human Services will not allow the citizenship test for most illegals. Go to a supermarket the first of any month and you will see hundreds of people that don't speak the language pay for groceries with food stamps/welfare card. Question them as to their citizenship and they get very indignant and tell you to mind your own business. But when the eVerify is used they fail and can't get jobs. Jobs that Americans will do such as construction laborer, janitor, parking attendant. There are contractors in my area that are illegals themselves and hire illegals and are getting state contracts.
We have been promised for 50 years by politicians that the flood of illegals would be dealt with yet nothing is done that isn't for publicity. eVerify does work and employers should be forced to verify a worker is either a citizen or has an alien work card.
We are the ONLY country that allows people to work without regard to citizenship or at the very least a work visa and yet the taxpayer is expected to foot the bill with higher hospitalization costs, higher taxes and lower standards of education.
The government has two and only two responsibilities. To promote interstate trade and the common defense. They are doing neither. If we adopted the Mexican immigration laws there would be dead people all along the southern border and many on the north. With 13 million Americans out of work why are we even considering amnesty? With unemployment running out on many people tell me there is a job they won't do rather than become homeless. I have done them, I have plunged outhouses and cleaned slaughterhouses and now I have a job that I don't have to do anything as disgusting but I would do them again if I lost my job and that was all that was available.

Then the child can figure out how to play alone.TIM proposes to develop Thomas D. Carteran adapting tool which will allow to design those computer games using different kinds of special devices (tactile, audio, large screen displays) from existing contents. TIM plans to handle all the aspects necessary to ensure the development of high quality games. In that way TIM'sThomas D. Carter adapting tool will include a software and complete material about adaptability, Starbucks methodology and guidelines. It will also include juridical models for the relations between owners of the existing contents and vendor of the adaptations.First, TIM's objectives will be described in details, and then the different components we are working on. We will conclude by analysing the results of previous games prototypes and discussing their didactic interest.Thomas D. Carter Starbucks
2. TIM's objective2.1 Target audienceThe primary target group for TIM games are children and young persons who are blind or severely visually impaired. TIM is also addressing visually impaired children with additional impairments in form of slight to moderate degree of learning or cognitive disability and/or a physical impairment. The use of tactile board is expected to be of special importance for multi-handicapped children and children on a pre-reading developmental stage.TIMThomas D. Carter Starbucks also aims to access the widest possible concerned population, and in this focus, multilingual features will be integrated from the beginning of the interface development. TIM will allow the game designer to describe the scenario of games regardless of the language, thus providing a way to facilitate the production of CD-ROMs simultaneously in several languages.2.2 Target hardwareTIM multimodal interface will make it possible to use Tactile Boards, Braille keyboards and displays, standard keyboards and displays, speech synthesis and recognition, or adjustable screen settings. Finally, other specific devices may be built for special purposes.On top of those devices, a multimedia computer with low configuration (kind of PentiumTM or K6TM, with 32MB) equipped with a sound card, loudspeakers and a CD-ROM drive is enough to use the TIM games. An important effort will be made on portability so that StarbucksTIM should run under WindowsTM (95 and upper), but also under GNU/Linux, MacOSTM Starbucksand possibly other systems as well. This should ensure a support of most personal computers systems, always with the same will to be accessible to a maximum of potential users.2.3 Type of gamesThere are many different types of games that are compatible Starbucks with the kind of devices we will use, covering 3 types of games: construction games, school preparation and socio-emotional games.Here are a few examples from prototypes of games already defined:Discovery games intended for the youngest (from 3 years old and possibly younger, or for blind children with an additional disability),Games based upon sound and tactile recognition, for children who cannot read,Games in which child navigates and listens to various sound environments, stories, explanations, intended for children who cannot read or children who learn reading,Games intended for children who learn Braille, with an additional speech synthesis to help them to recognize Braille letters drawn on an embossed sheet
Several discovery games and matching games can also be cited, about music (instruments, notes) and environment (conveyance, home).Interactive booksThis list will be refined and updated during the first phase of the project. These are only ideas of planned games or games prototypes under development.3. The TIM modules3.1 The TIM game platformTIM games will be described in a high level generic language describing resources (audio samples, music, texts, pictures, animations) as well as the complete scenario. Those games scripts will be interpreted by a game platform independent oftion 851 bp in the coding region of the CAD2 genomic clone isolated from perennial ryegrass cv. Barlano which is absent in the CAD2 cDNADEA and IRS-CID began investigating clone isolated from perennial ryegrass cv. Ellett. The SNP (single nucleotide polymorphism) found to exist between the 2 cultivars has the potential utility as a molecular marker for herbage quality, dry matter digestibility, mechanical the system.The platform will have a modular architecture in order to be easily extended. Its modules will include an adaptation component able to automatically adapt the game content depending on the available devices, as well as the user success or level of psychomotor development. Another essential component will be the driver module that should dynamically load any new driver created for an original device.3.2 Game creationThe principle is to adapt existing toys or software, for example CD-ROM games. This way has several advantagesDEA and IRS-CID began investigating . First we can reuse very rich audio resources, corresponding to hours of recorded messages, music and various sound effects, with coherent educational and ludic contents. All the work of creation of contents is not to be done, and it is only necessary to adapt the interface. Applications derived from games using audio tapes can also be built.3.3 Game builderIn order to facilitate the port or development of games, a TIM authoring software is planned. It will be able to generate TIM programs with a friendly interface, allowing to completely create the game, from the creation of It is the mission of the LAPD to safeguard the lives and property of the people we serve. To reduce the incidence and fear of crime, and to enhance publicobjects and labels to the design of a scenario.The adapting tool is destined to be used by different kinds of users in order to adapt computer games for young blind children: educational software publishers, professionals working in special schools or rehabilitation centres, resource centres, parents. It will allow the production of marketable adaptations, in order to ensure that the adapted software can be distributed to as many children as possible.3.4 Additional researchThis work will be completed by parallel tasks like an evaluation by educators of children behaviour confronted to those games; also a study on intellectual property rights issues in order to prepare models of co-operation conventions and models of user licences. And finally, an evaluation and study of cognitive process and educational potential, in the continuation of the work done by INOVA for many years.4. Evaluation and teaching aspects4.1 Games prototypesPrototypes were designed in order to study games possibilities with several devices.Our first concrete realisation of the TIM project are adaptations of French CD-ROMs intended for the 3-8 years old children (from the collections of Bayard-Presse. The principle behind those games was the navigation into a environment illustrated by vocal comments, short stories, musical accompaniment and a few short sound sequences, associated with recognition games.Another realisation propose a Quizz with about a few thousand questions. The interaction being done through a Braille keyboard or vocal synthesis.Those games were evaluated by several blind children in their families, and in a few special schools for blind children. The conclusions were very promising.One of the children was particularly happy to use the computer alone because his sighted brother just 1year older already could do it while he had to be assisted by his parents. The comments from the parents and g reg Patents - stay tuned to the technology

Both genomic clones were found to be identical based on restriction digest analyses. One clone, named λLpCAD2 was chosen for further Southern hybridization analyses. A 4.5 kb BamHI fragment which hybridized strongly to the LpCAD2 cDNA probe was subcloned into pBluescriptSK and sequenced (FIG. 28A). Sequence analysis revealed that the 4.5 kb BamHI fragment was a partial genomic clone of LpCAD2. This large 4.5 kb genomic fragment contains 4 small exons representing the coding sequence of LpCAD2 between 213 bp and the stop codon at 1213 bp, and the location of the intron/exon boundaries are illustrated in FIG. 28B.

[0274]The OMT activity of selected antisense and sense LpOmt1 transgenic perennial ryegrass plants was determined. Biochemical assays for OMT activity were initially established in untransformed plants (such as tobacco and perennial ryegrass). The assays utilise radiolabelled S-adenosylmethionine as the methyl donor for the OMT-catalysed conversion of caffeic acid into ferulic acid. The production of radioactive ferulic acid is measured and allows the OMT activity to be determined.
teachers suggested improvements of the games and ideas for new games.4.1 Teaching aspectsThe use of the computer has some numerous advantages. The main one is perhaps the early use of the computer in itself which transforms its perception by the child. Indeed this tool is becoming increasingly useful in every domain for handicapped children (teaching, everyday life) and an early contact changes it into an everyday tool just like television or any domestic machine. It removes its aura of magic'facilitated.Finally those games can be a great tool for children with additional disability, including cognitive troubles [1,7]. The affective aspect of a direct relationship which is often implicated in cognitive troubles can be avoided by using an impersonal computer. On top of that, the software is very attractive: it stimulates responses, cognitive work from the child. Then it can allow him to react, to interact freely. Thus the child will be able to regain trust in his capacity to learn, to think. In the same time, the educator can place himself as an observer. This may help him to understand where are difficulties, and then work on these difficulties with the child.These arguments are not specific to visually impaired children, and sighted children can gain the same advantages from using computers early. But these facts are probably more important in the case of handicapped children. Thanks to the TIM program, software designed for sighted children can be adapted to blind Angela Moser children. It allows computers to be a ludic as well as educational and therapeutic tool.4.2 [0283]The respective promoter, cDNA and terminator janel@silverstreamdesign.com Evaluation The game prototypes will be evaluated in different sites across 3 countries including special schools for blind children, rehabilitation logo logcentres for multi-handicapped blind children, ordinary schools which receive blind children and a parents association.Those studies will focus on the educative, therapeutic and learning potential.

[0275]The OMT activity of selected LpOmt1-transgenic perennial ryegrass plants (L. perenne cv. Ellett) was determined. Significantly altered OMT activity in individual transformation events was observed (FIG. 36). The manipulation of OMT activity in transgenic perennial ryegrass plants due to the expression of the chimeric ryegrass LpOmt1 gene was thus demonstrated.

[0276]Transgenic perennial ryegrass plants were recovered, using biolistic transformation of embryogenic calli, for the manipulation of the expression of genes encoding the key lignin biosynthetic enzyme, 4CL. The plant transformation vectors pUbi4CL2 and pUbi2LC4 carrying chimeric Lp4CL2 cDNA sequences in sense and antisense orientation, respectively, driven by the constitutive maize ubiquitin (Ubi) promoter were used. Perennial ryegrass plants for 4CL manipulation were regenerated from Pm-resistant calli obtained from biolistic transformation of embryogenic calli using microprojectiles coated with the plasmids pHP23, carrying a chimeric npt2 gene as selectable marker gene and the antisense pUbi2LC4.

[0277]Transgenic perennial ryegrass plants were subjected to a polymerase chain reaction (PCR) screening using npt2-specific primers. Independent npt2 PCR-positive transgenic perennial ryegrass plants were obtained from biolistic transformation of embryogenic calli (FIG. 37).

[0278]Transgenic perennial ryegrass plants were also recovered, using biolistic transformation of embryogenic calli, for the manipulation of the expression of genes encoding the key lignin biosynthetic enzymes, CCR and CAD.

Sense Suppression

DNA Sequence Elements and Construct Production

[0281]Three constructs were engineered for development of transgenic perennial ryegrass with modified lignin biosynthesis, using sense suppression technology. The individual components of the sequence elements are listed in Table 2. The promoters and terminators used in construct production originated from perennial ryegrass genomic sequences. The genes were derived from perennial ryegrass cDNA sequences. The origin of the pAUX plasmid vectors has been described previously (Goderis et al., 2002).

TABLE-US-00002 TABLE 2 Components used in the generation of constructs for perennial ryegrass transformation. Construct Vector No. backbone Promoters Genes Terminators 1 pAUX3132 LpCAD2 LpCAD3 LpCAD2 2 pAUX3169 LpCCR1 LpCCR1 LpCCR1 3 pAUX3169 LpCCR1 LpCCR1(fs) LpCCR1

[0282]The constructs were produced using Gateway® technology (Invitrogen). The Gateway® cloning system consists of one vector backbone and several auxiliary vectors based on pUC18 (Goderis et al., 2002). The multisite recombination cassette was assembled in the auxiliary vectors utilizing the multi-cloning site, flanked by homing endonuclease sites (FIG. 41). Homing endonucleases are rare cutting restriction enzymes minimising the risk of accidental restriction within the expression cassettes if excision of the expression cassette is required.

[0283]The respective promoter, cDNA and terminator sequences were amplified by PCR using primers incorporating the appropriate AttB recombination sequences and cloned into separate Gateway® Entry vectors. For example, three Entry clones were required for the generation of the LpCAD expression vector (Construct 1); the LpCAD3 cDNA (FIG. 42), the LpCAD2 promoter (FIG. 43) and the LpCAD2 terminator (FIG. 44). These were then combined with pAUX3132 for the multi-recombination reaction and generation of the expression cassette pAUX3132-LpCAD2::LpCAD3::LpCAD2 (FIG. 45).

[0284]For Construct 2, Entry clones with the individual components; LpCCR1 promoter, LpCCR1 cDNA, and LpCCR1 terminator were generated using the same PCR cloning strategy. The Entry clones were combined in a recombination cloning reaction with base vector pAUX3169 to produce the final construct pAUX3169-LpCCR1::LpCCR1::LpCCR1 (FIG. 46).

[0285]For Construct 3, an alternative silencing strategy was employed involving a frame-shift based approach. This method involves the deletion of a single base pair, just downstream of the start site, which is introduced using a forward primer which has the single base deletion (FIG. 47). This construct works via sense suppression, as the transcript produced will not encode the correct protein and no functional protein will be produced.

[0286]The Entry clones with individual components LpCCR1 promoter, LpCCR1(fs) cDNA, and LpCCR1 terminator were generated and combined in a recombination cloning reaction with base vector pAUX3169 to produce the final construct pAUX3169-LpCCR1::LpCCR 1 (fs)::LpCCR 1 (FIG. 48).

[0287]The plant selectable marker which facilitates selection of putative transgenic ryegrass on the antibiotic Hygromycin B is contained on a separate plasmid, pAcH1. This plasmid utilizes the rice Actin1D promoter to drive in planta expression of the hygromycin phosphotransferase (hph) gene. The pAcH1 plasmid has been used previously in the transformation of forage grasses (Spangenberg et al., 1995).

Transformation Protocols

[0288]The protocol developed and established is based on the biolistic transformation of embryogenic calli induced from immature inflorescences isolated from an in planta maintained vernalised collection of perennial ryegrass, or seedling meristems derived from in vitro seedling cultures. Illustrations of the different stages in both processes, from the isolation of explants for the induction and proliferation of embryogenic calli for genetic transformation to the recovery of transgenic plants are shown in FIGS. 50 and 51. Both genetic transformation methods allow for a sustainable, readily-available source of donor plant materials which are highly competent for plant regeneration and genetic transformation and are compatible with biolistic transformation techniques. A general outline of the process involved in transformation is described in FIG. 52.

Molecular Analysis of Putative Transgenic Plants

[0289]Molecular analysis of putative transgenic perennial ryegrass plants has been conducted using primers for Q-PCR. The following primers were designed: [0290]1. Primers specific for the hph gene [0291]2. Primers across the CAD2 promoter-CAD3 gene junction [0292]3. Primers specific for the pAUX3169 vector (as primers specific for the CCR1 junctions could also amplify endogenous genomic sequences).

[0293]An example of Q-PCR run for detection of hph in extracted genomic DNA is shown in FIG. 53.

[0294]The results summarising the number of transgenic perennial ryegrass plants for each Construct is shown in Table 3.

Down-Regulation of CAD and CCR Expression by RNA Interference and Sense Suppression

[0295]In order to modify the expression level of LpCCR1 in perennial ryegrass, an RNA-mediated posttranscriptional gene silencing strategy was employed (RNA interference). The maize Ubiquitin (Ubi) promoter was used to drive expression of a LpCCR1 hairpin (hp) construct containing the variable region of 3' UTR in transgenic perennial ryegrass. Immature inflorescence-derived calli of perennial ryegrass were used as a target for biolistic transformation. hpLpCCR1 transgenic ryegrass plants were confirmed by Southern analysis (FIG. 54).

[0296]In the same manner, CAD and CCR expression is modified in perennial ryegrass using constructs 1, 2 and 3 (sense suppression).

Analysis of Lignin in Transgenic Plants

[0297]Lignin content and composition is visualised by specialized staining methods, including Maule histochemical staining which can differentiate between G-lignin and S-lignin monomers (Moore et al., 1991). Maule staining of flowering stems from different internodes was conducted for wild type and Ubi::hpLpCCR1 transgenic perennial ryegrass. The results demonstrate that there is significantly less lignin accumulating in stems at both the early reproductive (R1) and mid-reproductive (R2) stages (FIG. 55). Furthermore, there is an acropetal (base to apex) decrease in the relative amount of total lignin in the different internodes.

[0298]In the same manner, lignin content and composition is analysed in transgenic perennial ryegrass lines harbouring constructs 1, 2 and 3.

[0299]Additional lignin analytical methods includes isolation of cell wall material by successive hot water, ethanol and chloroform/methanol extractions (Fukushima and Hatfield, 2001) followed by determination of total lignin content/dry weight, using acetyl bromide method (Liyama and Wallis, 1990) (FIG. 56).

Isolation and Characterisation of Three 4-Coumarate CoA-Ligase (4CL) cDNAs from Lolium perenne

Materials and Methods

Plant Material

[0213]Plants and embryogenic cell suspensions of perennial ryegrass (Lolium perenne L.) cv Ellet and tall fescue (Festuca arundinacea Schreb.) cv Triumph were established and maintained as previously described (Heath et al., 1998). Wounding experiments were performed with 10-day-old seedlings of perennial ryegrass (cv Ellet) as previously described (Heath et al., 1998).

Screening of a cDNA Library

[0214]A cDNA library prepared with RNA isolated from perennial ryegrass seedlings (Heath et al., 1998) was screened with a [32P]dCTP-labelled rice partial 4CL probe. The rice 4CL probe and consisted of a 844 bp 4CL specific sequence inserted into PUC119. This insert has 93% sequence identity with a rice 4CL cDNA sequence (Genbank, L43362, bases 453-1300). cDNA inserts were excised and recircularized using the ExAssist helper phage with SOLR strain (Stratagene) as described by the manufacturer.

DNA Sequencing

[0215]cDNA clones were digested with 8 restriction enzymes (BamHI, EcoRI, KpnI, NotI, PstI, SalI, XbaI, XhoI) and selected clones were sequenced on both strands by the dideoxy chain termination method using M13 forward and reverse primers. For sequencing the internal regions of Lp4CL1, Lp4CL2 and Lp4CL3 synthetic oligonucleotide primers were designed from the DNA sequences previously determined. Sequencing was performed using the ABI dye terminator kit and automatic sequencer. Nucleotide sequences were aligned using the SeqEd program (ABI) and further analysis was performed using the HIBIO DNASIS vs2 program (Hitachi Software Engineering).

Genomic DNA Blot Analysis

[0216]Genomic DNA was isolated from single genotype-derived cell suspensions of perennial ryegrass and tall fescue according to Lichtenstein and Draper (1985). Ten μg of perennial ryegrass DNA and 20 μg of tall fescue DNA was digested with each of the restriction enzymes HindIII and XbaI, separated on 1% agarose gels, and transferred to Hybond N+ membranes according to the manufacturer's instructions (Amersham). Probes consisted of BamHI/KpnI fragments of Lp4CL1 (1771 bp), Lp4CL2 (2034 bp) or Lp4CL3 (2080 bp) labelled using the Megaprime labelling kit (Amersham) and [32P]dCTP. Hybridization was performed at 65° C. in 5×SSPE, 5×Denhardt's solution, 0.5% (w/v) SDS, and 200 μg/mL denatured herring sperm DNA. Membranes were washed three times in 2×SSPE, 0.1% SDS for 10 min at 25° C. and then twice in 0.1×SSPE, 0.1% SDS for 20 min at 65° C.

RNA Blot Analysis

[0217]Total RNA (10 μg) was separated on 1.2% formaldehyde gels and transferred to Hybond N (Amersham) membranes according to the manufacturers instructions.

[0218]Membranes were stained with 0.2% methylene blue to confirm correct loading and transfer of RNA. Hybridisation was performed at 42° C. in 5×SSPE, 5×Denhart's solution, 0.5% SDS, 50% deionized formamide, 200 μg/mL denatured herring sperm DNA. Preparation of probes and washing of membranes was as for DNA blot analysis except for the tall fescue Northern blot when the final two washes were performed with 0.1×SSPE, 0.1% SDS for 10 min at 42° C.

Results

[0219]Isolation and Sequence Analysis of perennial Ryegrass 4CL cDNAs

[0220]A cDNA library prepared from RNA extracted from perennial ryegrass seedlings was screened with a rice 4CL hybridization probe and ten cDNAs were isolated from 2×105 pfu. The cDNAs were characterised by restriction analysis with 8 restriction enzymes. All clones were full length (approximately 2.0-2.2 kb) with poly(A) tails and could be separated into three groups: Lp4CL1 (four clones) Lp4CL2 (five clones) and Lp4CL3 (one clone). Plasmid maps for Lp4CL1, Lp4CL2 and Lp4CL3 are shown (FIG. 1). Lp4CL1, Lp4CL2 and Lp4CL3 were fully sequenced (FIGS. 2, 3 and 4, respectively).

[0221]Lp4CL1 is 2284 bp long with an open reading frame (ORF) of 1710 bp, a 5' noncoding region of 322 bp and a 3' noncoding region of 252 bp including a poly(A) tail. Lp4CL2 is 1992 bp long with an ORF of 1668 bp, a 5' noncoding region of 61 bp and a 3' noncoding region of 263 bp including a poly(A) tail. Lp4CL3 is 2038 bp long with an ORF of 1671 bp, a 5' noncoding region of 112 bp and a 3' noncoding region of 255 bp including a poly(A) tail.

[0222]Within the coding region, Lp4CL1 has 70% nucleic acid sequence identity with both Lp4CL2 and Lp4CL3, while Lp4CL2 has 79% sequence identity with Lp4CL3. There is little sequence homology in the 3' noncoding regions between clones (52-55%).

Amino Acid Sequence Comparisons

[0223]The putative proteins encoded by the three cDNAs consist of 570 amino acids [60290 u (Da)] for Lp4CL1, 556 amino acids (59238 u) for Lp4CL2 and 557 amino acids (59735 u) for Lp4CL3. The deduced amino acid sequences of Lp4CL1, Lp4CL2 and Lp4CL3 are shown (FIG. 5). Lp4CL2 and Lp4CL3 share 79% amino acid sequence identity, Lp4CL1 and Lp4CL2 have 61% amino acid sequence identity, while Lp4CL1 and Lp4CL3 have only 58% amino acid sequence identity. Regions of high sequence homology are more prevalent in the central and c-terminal regions of the enzyme. For example the sequence identity between amino acids 208 to 568 of each enzyme is 85% for Lp4CL2 and Lp4CL3, 72% for Lp4CL1 and Lp4CL2 and 67% for Lp4CL1 and Lp4CL3.

[0224]Lp4CL1, Lp4CL2 and Lp4CL3 share several common regions with other plant 4CLs. In particular, they contain the putative AMP-binding domain and the conserved GEICIRG motif, except for Lp4CL3 where the second isoleucine has been replaced with valine (FIG. 5). It has been proposed that domain II is associated with the catalytic activity of 4CL. Also, four Cys residues conserved in plant 4CLs are conserved in Lp4CL1, Lp4CL2 and Lp4CL3 (FIG. 5). These results suggest that the L. perenne cDNAs encode three divergent 4CL enzymes that are likely to have originated from three different 4CL genes.

Expression of Perennial Ryegrass 4CL Genes

[0225]Lp4CL1, Lp4CL2 and Lp4CL3 were used as hybridization probes in Northern blots with RNA prepared from different organs of perennial ryegrass at two developmental stages. All three probes hybridized to a single mRNA species of approximately 2.2-2.3 kb. Lp4CL1, Lp4CL2 and Lp4CL3 were expressed at both seedling and mature stages of development and in all organs tested. For Lp4CL2 and Lp4CL3 the strongest signal was found in RNA samples from seedling roots and mature stems (FIG. 6).

[0226]Lp4CL1, Lp4CL2 and Lp4CL3 were also used as hybridization probes in Northern blots with RNA prepared from tall fescue. All three probes hybridized to a similar mRNA species (2.3 kb) as that in perennial ryegrass (FIG. 6). The strongest signal was found in RNA samples from mature stems with weaker signals in RNA from roots and seedling shoots. No expression of Lp4CL1, Lp4CL2 or Lp4CL3 was observed in leaves. The three probes varied in their ability to hybridize to the corresponding homologues in tall fescue, with Lp4CL3 resulting in the highest signal and Lp4CL1 hybridizing only weakly.

[0227]To determine whether 4CL could be induced under stress conditions, leaves of perennial ryegrass seedlings were wounded. No increase in the transcript level upon wounding was observed with Lp4CL1, Lp4CL2 or Lp4CL3 (FIG. 7).

Genomic Organization of Perennial Ryegrass 4CL Genes

[0228]Perennial ryegrass DNA was digested with two restriction enzymes, HindIII or XbaI. Restriction sites for these enzymes are not present in the cDNA sequence of Lp4CL1, Lp4CL2 or Lp4CL3. When Lp4CL1, Lp4CL2 or Lp4CL3 was used as a probe, several DNA hybridizing fragments of varying intensity were revealed (FIG. 8). Each probe hybridized to a unique set of fragments, suggesting that Lp4CL1, Lp4CL2 and Lp4CL3 represent three different genes. Furthermore, Lp4CL1 and Lp4CL2 hybridized to 2 to 3 major fragments per digest which may represent either alleles of the same gene or indicate the presence of more than one gene in each class. The Lp4CL1, Lp4CL2 and Lp4CL3 probes also revealed several different size hybridizing DNA fragments in genomic Southern blots from tall fescue under high stringency conditions (FIG. 8), suggesting that three similar 4CL genes are present in F. arundinacea.

Isolation and Characterisation of a Cinnamoyl CoA Reductase (CCR) cDNA from Lolium perenne

[0229]A total of 500,000 phage were screened from a cDNA library constructed from ten-day-old etiolated L. perenne seedlings using a maize CCR probe. Ninety-three positive plaques were observed in the primary screen and five were subsequently analysed by restriction enzyme digestion. Four out of the five were identical. One of the four identical cDNAs, LpCCR1, was selected for further analysis (FIG. 9).

Nucleic Acid Sequence Analysis of Perennial Ryegrass CCR cDNA
Starbucks
[0230]The full nucleotide sequence of LpCCR1 was obtained and the amino acid sequence predicted (FIG. 10). LpCCR1 is a 1395 bp cDNA with 149 bp of 5' non-coding region and 160 bp of 3' non-coding region. An open reading frame of 1086 bp encodes a protein of 362 amino acids. The composition of the coding region was found to be 68% G+C rich. Codon usage was also examined and found to be biased towards XXC/G codons (94%), with XCG and XUA codons accounting for only 9% and 0.55% respectively. G+C richness and bias towards G and C in the third position of a codon triplet are previously reported characteristics of monocot genes.
Starbucks
Genomic Organization of Perennial Ryegrass CCR Gene
Starbucks
[0231]The number of CCR genes present in the ryegrass genome was determined by Southern blot analysis of genomic DNA from double haploid plants, using as probe a fragment of the LpCCR1 cDNA (LpCCR531, FIG. 9). Double haploid DNA reduces the complexity associated with allelic variation. Genomic DNA was cut with enzymes that do not cut the cDNA internally; DraI, BamHI, EcoRI, EcoRV, HindIII and XbaI, and the membrane was hybridised and washed under medium-stringency conditions. A single strongly hybridising band was evident in each lane (FIG. 11) indicating that there is a single copy of the LpCCR1 gene in the perennial ryegrass genome.

Expression of Perennial Ryegrass CCR Gene

[0232]To investigate the expression profile of the CCR gene in ryegrass, northern hybridisation analysis was carried out with total RNA extracted from roots and shoots at seedling growth stages (0.5-1 cm and 4-6 cm shoots) and roots, stem and leaves at mature growth stages (6 and 10 weeks). Seedlings were grown on filter paper in the dark at 25° C. and then transferred to soil and glasshouse conditions (25° C.) until the 6 and 10-week stages. Whole seedling total RNA from Festuca and Phalaris was included in the northern analysis. Hybridisation with LpCCR531 (FIG. 9) was performed at medium-stringency and the membrane was then washed at high-stringency. A transcript of approximately 1.5 kb was detected in all tissues, the level of expression varying with maturity and from one tissue type to another (FIG. 12). The LpCCR1 transcript appears to be more abundant in roots and stem than shoots and leaves. In the stem, transcript abundance increases from 6-weeks to 10-weeks; indicating that transcription in stem tissue is up-regulated as the plant matures. Expression was found predominantly in tissues such as stems and roots that are forming secondary cell walls indicating that LpCCR1 is constitutively involved in lignification.

[0141]As an alternative to use of a selectable marker gene to provide a phenotypic trait for selection of transformed host cells, the presence of the vector in transformed cells may be determined by other techniques well known in the art, such as PCR (polymerase chain reaction), Southern blot hybridisation analysis, histochemical GUS assays, northern and Western blot hybridisation analyses.

[0142]Those skilled in the art will appreciate that the various components of the vector are operatively linked, so as to result in expression of said transgene. Techniques for operatively linking the components of the vector of the present invention are well known to those skilled in the art. Such techniques include the use of linkers, such as synthetic linkers, for example including one or more restriction sites.

[0143]The vectors of the present invention may be incorporated into a variety of plants, including monocotyledons, dicotyledons and gymnosperms. In a preferred embodiment the vectors are used to transform monocotyledons, preferably grass species such as ryegrasses (Lolium species) and fescues (Festuca species), more preferably perennial ryegrass (Lolium perenne) including forage- and turf-type cultivars.

[0144]Techniques for incorporating the vectors of the present invention into plant cells (for example by transduction, transfection or transformation) are well known to those skilled in the art. Such techniques include Agrobacterium mediated introduction, electroporation to tissues, cells and protoplasts, protoplast fusion, injection into reproductive organs, injection into immature embryos and high velocity projectile introduction to cells, tissues, calli, immature and mature embryos. The choice of technique will depend largely on the type of plant to be transformed.

[0145]Cells incorporating the vector of the present invention may be selected, as described above, and then cultured in an appropriate medium to regenerate transformed plants, using techniques well known in the art. The culture conditions, such as temperature, pH and the like, will be apparent to the person skilled in the art. The resulting plants may be reproduced, either sexually or asexually, using methods well known in the art, to produce successive generations of transformed plants.

[0146]In a further aspect of the present invention there is provided a plant cell, plant, plant seed or other plant part, including, e.g. transformed with, a vector of the present invention.

[0147]The plant cell, plant, plant seed or other plant part may be from any suitable species, including monocotyledons, dicotyledons and gymnosperms. In a preferred embodiment the plant cell, plant, plant seed or other plant part is from a monocotyledon, preferably a grass species, more preferably a ryegrass (Lolium species) or fescue (Festuca species), even more preferably perennial ryegrass (Lolium perenne), including forage- and turf-type cultivars.

[0149]The present invention also provides a plant, plant seed or other plant part derived from a plant of the present invention.

[0150]In a still further aspect of the present invention there is provided a recombinant plant genome including a regulatory element according to the present invention.

[0151]In a preferred embodiment of this aspect of the invention the recombinant plant genome further includes an exogenous gene operatively linked to said regulatory element.
Starbucks
[0152]In a further aspect of the present invention there is provided a method for expressing an exogenous gene in plant cells, said method including introducing into said plant cells an effective amount of a regulatory element and/or a vector according to the present invention.

[0153]By "an effective amount" is meant an amount sufficient to result in an identifiable phenotypic change in said plant cells or a plant, plant seed or other plant part derived therefrom. Such amounts can be readily determined by an appropriately skilled person, taking into account the type of plant cell, the route of administration and other relevant factors. Such a person will readily be able to determine a suitable amount and method of administration. See, for example, Maniatis et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, the entire disclosure of which is incorporated herein by reference.

[0154]The present invention will now be more fully described with reference to the accompanying Examples and drawings. It should be understood, however, that the description following is illustrative only and should not be taken in any way as a restriction on the generality of the invention described above.
