摘要： The present invention is related to a birch BpCol2 nucleic acid sequence and BpCol2-like nucleic acid sequences, which are related to CONSTANS (CO) gene family, and gene products thereof as well as methods and use therein for influencing growth of a plant or roots of a plant. Particularly the invention is related to cloning and expression of BpCol2 gene in plants. The invention is further related to DNA constructs, vectors, transgenic cells, plants and seeds comprising said nucleic acid sequences and gene products.

摘要： Two nucleotide sequences encoding two different polypeptides found in yeast trehalose synthase have been isolated and cloned. A third polypeptide has been isolated from the enzyme and characterized, and a method is provided to isolate and clone the nucleotide sequence encoding this polypeptide. The coding sequences can be inserted into suitable vectors and used to transform host cells. The transformed cells will produce increased amounts of trehalose compared to the untransformed wild types and have increased tolerance to a variety of stresses, in particular to decreased availability of water. The invention may be used to improve the stress tolerance of organisms, to increase the storage life of foodstuffs and to produce trehalose economically on an industrial scale in an organism (e.g. baker's yeast) that is a traditional and safe foodstuff.

摘要： The present invention is related to plant molecular biology. Particularly it is related to nucleic acids and methods for conferring disease resistance in plants. It is also related to potato receptor-like kinases (PRKs) and PRK cDNA or nucleic acid sequences and their gene products for conferring enhanced resistance to pathogens and pests. The invention is further related to novel receptors and ligands and their use in detecting plant-pathogen interactions.
