The invention discloses nucleic acid encoding an FY polypeptide with the sequence shown in Annex 2. Also provided are vectors, host cells and plants. Methods of the invention include the use of nucleic acids to express or down-regulate FY in plants. The methods may be used to affect flowering time or juvenile phase length in plants.

The present invention relates to a method for in vitro creation of molecular libraries evolution of protein function. Particularly, it relates to variability and modification of protein function by shuffling polynucleotide sequence segments. A protein of desired characteristics can be obtained by incorporating variant peptide regions (variant motifs) into defined peptide regions (scaffold sequence). The variant motifs can be obtained from parent DNA which has been subjected to mutagenesis to cre...

The invention provides a method for generating a polynucleotide sequence or population of sequences from parent single stranded polynucleotide sequences encoding one or more protein motifs, comprising the steps of (a) providing single stranded DNA constituting plus and minus strands of parent polynucleotide sequences; (b) digesting the single stranded polynucleotide sequences with a nuclease other than DNase I to generate populations of single stranded fragments; (c) contacting said fragments ge...

The present invention provides methods and compositions useful in treating certain diseases herein termed "Aberrant Programming Diseases," including cancer and AIDS. According to one aspect of the invention, there is provided a method for treating an individual having an Aberrant Programming disease comprising administering to said individual an effective amount of a composition selected from the group consisting of an expression vector, a double stranded oligodeoxynucleotide, and an antisense o...

Plants having transformed plastid genomes comprising a construct comprising attL and attR sites and a gene of interest, where the plants comprise an integrase and, optionally a selectable marker gene, and methods of making the plants.

A site specific recombination system and methods of use thereof are disclosed for manipulating the genome of higher plants. Compositions and methods for expressing immunogenic proteins using the site specific reombination system are also provided.

Disclosed are isolated .beta.-amyrin synthase-encoding cDNA and genomic nucleic acids, which are involved in saponin synthesis. Also provided are complementary sequences, vectors, transformed host cells, transformed plants, and methods for influencing or affecting triterpene synthesis, and hence resistance to a fungal pathogen of a plant using .beta.-amyrin synthase encoding nucleic acids.

Isolated PGE synthase, provided from encoding nucleic acid. Methods of production and use. Assays for modulators, especially inhibitors, of PGE synthase activity.

Disclosed are a variety of methods for achieving enhanced expression from a target nucleotide sequence in a plant e.g. comprising the step of transiently introducing into a tissue of a plant (e.g. a leaf) a first nucleic acid comprising the target nucleotide sequence and a second nucleic acid encoding a Post Transcriptional Gene Silencing (PTGS) suppressor protein (preferably of viral or plant origin), wherein the first and second nucleic acids are comprised within a single binary vector constru...

The present invention relates to materials and methods for treatment of hepatitis C. More closely, the invention relates to human monoclonal antibodies against HCV E1 antigen, to a reagent comprising such antibodies, and to vaccine compositions comprising such antibodies. Futhermore, the invention relates to a method of treating or preventing HCV infection by administration of a vaccine composition comprising the monoclonal antibodies of the invention.
