摘要：
AtPHB2 was cloned from Arabidopsis thaliana and localized to mitochondria. AtPHB2 expression in A. thaliana increased under different stresses, and promotion of seed germination and plant growth was observed in transgenic plants. In terms of physiological indices, the transgenic plants were more resistant to saline-alkali and oxidative stresses than wild-type and mutant plants. The transgenic plants also had the highest K+/Na+ ratio after 24 h of salt treatment and maintained lower H2O2 contents than wild-type and mutant plants under stress. Taken together, these results reveal that AtPHB2 affects plant tolerance against salt stresses and is involved in ROS decrease mechanisms.
