摘      要：Plant growth and crop productivity are severely affected by abiotic stress on a global ***40 repeat-containing proteins play a significant role in the development and environmental adaptation of *** this study,OsABT,a stress response gene,was cloned from rice(Oryza sativa ***).OsABT encodes a protein containing seven WD40 *** analysis revealed that the OsABT gene was first up-regulated and then down-regulated following treatment with abscisic acid(ABA)and NaCl,but was down-regulated when treated with *** localization results showed that OsABT was located in the cytoplasm and nucleus of Arabidopsis *** transgenic Arabidopsis showed significantly increased tolerance to ABA and salt stress during plant seedling ***,the transgenic lines were more sensitive to drought ***,OsABT can interact with OsABI2,a component of ABA signaling *** results showed that OsABT plays a positive regulatory role in response to salt stress and a negative role in response to drought stress in Arabidopsis.
