The SmWRKY12-SmRAP2-7-SmEXPA13 module in Salix matsudana koidz enhances plant tolerance to drought stress.

WRKY transcription factors play key roles in plant responses to abiotic stress. In this study, we cloned and characterized the drought-induced WRKY gene SmWRKY12 from Salix matsudana Koidz. Following drought treatment, SmWRKY12 was significantly upregulated in the roots of the drought-tolerant willow variety 9901.

Regulation of SmEXPA13 expression by SmMYB1R1-L enhances salt tolerance in Salix matsudana Koidz.

Expansins, cell wall proteins, play a significant role in plant stress resistance. Our previous study confirmed the expression of the expansin gene SmEXPA13 from Salix matsudana Koidz. enhanced salt tolerance of plants.
