METHODS OF ABIOTIC STRESS TOLERANCE ENHANCEMENT AND/OR BIOMASS INCREASE FOR PLANTS, AND PLANTS OBTAINED BY METHOD Russian patent published in 2009 - IPC C12N15/82 C12N15/29 C12N5/14 

FIELD: biology.

SUBSTANCE: plant cell is transformed by exogenous polynucleotide, expression of which provides cell with enhanced tolerance to abiotic stress, with further cultivation of grown plant from the cell. Transformation is performed by introduction of construction with constitutive or abiotic stress-induced promoter to the cell. Either the plant is infected by avirulent virus including indicated exogenous polynucleotide which, when expressed in plant, provides plant with tolerance to abiotic stress.

EFFECT: resistance to abiotic stress, such as soil salinity, water deficiency, low or high temperature etc.
