| 摘 要： | H2O2是一种多效性分子,在植物应对非生物胁迫过程中起着重要作用。在一定的浓度范围内,H2O2作为信号分子通过参与多种信号转导途径调节相关的基因表达以及生理代谢过程,但是H2O2的过度积累会引起细胞组分的降解,导致细胞死亡。因此,维持植物体内H2O2的动态平衡十分必要。综述了非生物胁迫条件下H2O2在植物中的产生、降解及在信号传导中的作用。

| Abstract: | Hydrogen peroxide(H2O2) is a pleiotropic molecule,playing key roles in regulating plant response to various abiotic stresses.As a signal molecule,H2O2 is involved in controlling the expression of stress-related genes and physiological processes via different signal transduction pathways in a certain range of concentration.Excess concentration of H2O2 will cause the degradation of cell components and cell death.Thus,it is necessary to maintain the balance between production and scavenging of H2O2.This paper ... |
