Title
(EN) METHODS OF IMPROVING DROUGHT AND SALT RESISTANCE IN A PLANT AND GENETICALLY ENGINEERED PLANTS WITH IMPROVED DROUGHT AND SALT RESISTANCE
Abstract
(EN)

The present disclosure provides methods for increasing drought resistance, salt resistance, and biomass production of a plant. The methods encompass expression of DiGeorge-Syndrome Critical Region 14 (DGCR14) gene in the plant. In comparison to a plant not manipulated in this manner, the disclosed, genetically-modified, plants display improved drought resistance and salt resistance. Also provided are plants that can be obtained by the method according to the invention, and nucleic acid vectors to be used in the described methods.
