Regulation of abscisic acid signaling in plants

摘要

The present invention provides a method of modulating the abscisic acid signaling in plants. The method comprises introducing into a plant a recombinant expression cassette comprising a promoter that is operably linked to the polynucleotide ABH1. In a preferred embodiment of the present invention, the ABH1 polynucleotide sequence is at least about 70% identical to (b) SEQ ID NO: 2 or comprises a sequence that is at least about 70% identical to (a) SEQ ID NO: 1 I encodes a ABH1 polypeptide having.
