This invention discloses the application of the wheat
gene TaPSS2 in improving
plant drought resistance, belonging to the field of
functional genomics. The
nucleotide sequence of the wheat
gene TaPSS2 is shown in SEQ ID NO: 2. Transforming this
gene into the model
plant Arabidopsis thaliana can significantly improve the
drought resistance of
Arabidopsis. If the wheat gene TaPSS2 is transformed into wheat, rice, maize, cauliflower, and other plants, it is possible to obtain new
germplasm with drought-resistant characteristics, which is of great significance for the breeding of superior
crop varieties and their widespread application in production.
