The major results of this proposal are as follows:(1) ABA induces a rapid, substantial accumulation of apoplastic H2O2 in mesophyll and bundle sheath cells of maize leaves, and the accumulation of apoplastic H2O2 is involved in the induction of the chloroplastic and cytosolic antioxidant enzymes.(2) ABA-induced H2O2 production activates a 46 kDa MAPK, which in turn induces the expression of antioxidant genes and up-regulates the activities of antioxidant enzymes. The activation of MAPK also enhances H2O2 production, forming a positive amplification loop.(3) Water stress also induces the activation of a 46 kDa MAPK, which is dependent on the accumulation of ABA and H2O2 production induced by water stress and involved in the up-regulation of the expression and the activities of antioxidant enzymes.(4) ABA-induced H2O2 production mediates NO generation, which in turn activates a 46 kDa MAPK and results in the up-regulation in the expression and the activities of antioxidant enzymes in ABA signaling. NO-independent signaling is also involved in ABA- and H2O2-induced antioxidant defense.

本项目的主要研究结果如下：（1）ABA诱导的H2O2产生主要出现在叶肉细胞与维管束鞘细胞的质外体中，质外体H2O2的积累能够上调叶绿体与细胞溶质中抗氧化酶的活性；（2）ABA诱导的H2O2产生活化一个46kDa的MAPK，由此而导致编码抗氧化防护酶基因的表达与酶活性的上调；而MAPK的活化也能增强H2O2的产生，从而形成一个正的反馈调节环；（3）水分胁迫也能诱导一46kDa MAPK活化，这一MAPK活化依赖于水分胁迫诱导的ABA积累以及H2O2的产生，同时参与水分胁迫诱导的抗氧化防护基因的表达与抗氧化酶活性的上调；（4）ABA诱导一个依赖于H2O2的NO产生，NO活化一个46kDa的MAPK，从而导致抗氧化防护基因的表达以及抗氧化酶活性的上调；同时一个不依赖于NO的信号转导途径也存在于ABA诱导的抗氧化防护过程中。
