dc.description.abstract | Abscisic acid-, stress-, and ripening-induced (ASR) proteins play an important role in protecting plants against adverse environmental conditions. Here, we identified 24 ASR genes in the wheat genome and analyzed their characteristics. Among these, five ASR genes highly induced by abscisic acid (ABA) and polyethylene glycol were cloned and further characterized. The TaASR genes were expressed in response to different abiotic stresses and ABA and were found to be localized in the nucleus and plasma membrane of transformed tobacco cells. Brachypodium distachyon transgenic plants overexpressing TaASR2D showed enhanced drought tolerance by regulating leaf transpiration. The expression levels of stress-related and ABA-responsive genes were higher in transgenic plants than in wild-type plants under drought stress conditions. Moreover, overexpression of TaASR2D increased the levels of both endogenous ABA and hydrogen peroxide in response to drought stress, and these plants showed hypersensitivity to exogenous ABA at the germination stage. Furthermore, plants overexpressing TaASR2D showed increased stomatal closure. Further analysis revealed that TaASR2D interacts with ABA biosynthesis and stress-related proteins in yeast and tobacco plants. Collectively, these findings indicate that TaASR2D plays an important role in the response of plants to drought stress by regulating the ABA biosynthesis pathway and redox homeostasis system. | - |
