摘要:
The invention provides novel polypeptides having phospholipase activity, including, e.g., phospholipase A, B, C and D activity, patatin activity, phosphatidic acid phosphatases (PAP)) and/or lipid acyl hydrolase (LAH) activity, nucleic acids encoding them and antibodies that bind to them. Industrial methods, e.g., oil degumming, and products comprising use of these phospholipases are also provided.
摘要:
The present invention relates to cultivated plant of the species Solanum lycopersicum comprising a myb12 allele having one or more mutations, said mutations resulting in production of a mutant myb12 protein, fruits of such plants exhibiting a pink appearance and in addition comprising a mutant cuticle deficiency (cd) allele, whereby the fruits become glossy.
摘要:
The present invention relates to novel glycosyl transferases from Vitis vinifera that are capable of catalyzing the formation of certain glycosides with high efficiency, to nucleic acid molecules encoding such glycosyl transferases, to vectors, host cells and transgenic plants comprising nucleic acid sequences coding for such glycosyl transferases, and to methods for preparing and uses of such glycosyl transferases.
摘要:
The present invention discloses isolated polynucleotides encoding WUSCHEL-related homeobox4 proteins from two species of jute plants, namely, the Corchorus olitorius (“C. olitorius”) and Corchorus capsularis (“C. capsularis”), and corresponding polypeptides derived therefrom. The disclosed polynucleotide sequences encode WUSCHEL-related homeobox4 polypeptides (WOX4), which possess catalytic activities in enhancing fiber production in jute. The present invention also relates to the plants having a modulated expression of a nucleic acid encoding a WOX4 polypeptide, which have enhanced fiber yield relative to corresponding wild type plants or other control plants. Vectors, expression constructs and host cells comprising and/or consisting of the nucleotide sequences of the protein are also provided. Also disclosed are methods for producing the proteins and methods for modifying the proteins in order to improve their desirable characteristics. The proteins of the invention can be used in a variety of ways, including inducing, initiating, improving, or enhancing plant growth, plant height, fiber and seed yield.
摘要:
The present invention discloses genetically engineered plants which display altered structure or morphology. The transgenic plants express a cell wall modulation transgene or gene construct that results in the altered structure or morphology. The altered structure or morphology can be associated with, for example, altered biomass, growth, yield, greater or less resistance to biodegradation, more or less digestible to ruminants, altered cellulose content, larger leaves/normal hypocotyls or smaller leaves/longer hypocotyls, etc. compared to a non-transgenic plant of the same species. The cell wall modulation transgene can be any cellulose binding domain, a cellulose binding protein, or a cell wall modifying protein or enzyme such as endoxyloglucan transferase, xyloglucan endo-transglycosylase, an expansin, cellulose synthase, or a novel isolated endo-1,4-²-glucanase of Arabidopsis thaliana. The invention also discloses transgenic plants containing a gene construct comprising a promoter operably linked to the cell wall modulation protein or polypeptide gene and may further comprise a sequence encoding a secretion signal peptide. In particular, the invention discloses transgenic plants containing a gene construct comprising the cell promoter, operably linked to the cell signal peptide and any cellulose binding domain.
摘要:
The present invention relates to a method for genetically modifying the genome of a hybrid plant by replacing one or more of its chromosomes or chromosome fragments with the corresponding chromosome or chromosome fragment of one or more donor parents. The invention uses the reverse breeding technique to construct a novel type of substitution and introgression libraries that can be used for accelerated breeding and hybrid correction. These libraries and their use are also part of this invention.
