摘　　要：As one of the main staple cereal crops,wheat(Triticum aestivum L.)is cultivated worldwide,commonly in semi-arid or arid climates(Zhou et al.,2020;Mao et al.,2023).However,with increasingly severe weather events associated with global warming,drought stress presents a growing challenge to food security and production,to which arid regions may be especially vulnerable(Lesk et al.,2016;Eckardt et al.,2023).One key step in addressing this threat is to define the plant molecular mechanisms underlying drought stress response in order to improve crop resilience or tolerance to water deficit conditions(Zhang et al.,2021;He et al.,2024).Abscisic acid(ABA)is a key hormone in plants that regulates various physiological and molecular responses under drought stress,such as stomatal closure,gene activation,and cellular protection(Yoshida et al.,2015;Zhang et al.,2021).Essential to plant stress response are core mediators of the ABA signaling pathway,especially SNF1-related protein kinases 2s(SnRK2s)and ABA-response element(ABRE)-binding factors(ABFs)(Fujita et al.,2013;Yoshida et al.,2015).However,as of yet,the role of SnRK2s and ABFs in regulating drought response in wheat is not well understood.Here,our findings show that a TaSnRK2s-TaABF2 regulatory module can enhance tolerance to prolonged water deficit by directly modulating drought-responsive genes.
