isolated polynucleotide, expression cassette, plant, or part of it, transgenic seed, a method to increase the plant's tolerance to abiotic stress.

摘要

isolated polynucleotide, expression cassette, method for obtaining a plant or part of it and a method for increasing the plant's tolerance to abiotic stress the present invention provides compositions and methods for regulating the expression of nucleotide sequences in a plant. compositions comprise new polypeptides involved in the modulation of gene expression in response to abiotic stress, such as dry or cold, and polynucleotides encoding the polypeptides. methods for expressing polynucleotides in a plant and improving tolerance to plant cold and / or drought are also provided.
