这篇综述,首先描述了植物一病原物相互作用的氧化猝发;其次,旨在弄清活性氧形成的调节和参与活性氧形成的化合物特性方面目前的突出进展;再次,讨论活性氧对抗病性的可能功能,使读者能够回顾这个课题的以往论述(Shtherland,1991).1 氧化猝发中的活性氧活性氧一般是植物细胞叶绿体、线粒体和其它细胞空间,所含有的氧化酶在氧化还原过程中,由低水平电子传递而产生的.氧化猝发期中,分子氧首先单电子还原形成超氧离子(O_2~-),而后,水溶液中的O_2~-自发歧化形成H_2O_2.反应如下:
This review first described the oxidative burst of plant-pathogen interactions; second, it aimed to understand the current state of the art in regulating the formation of reactive oxygen species and the properties of compounds involved in the formation of reactive oxygen species. Thirdly, The possible functions of sexuality allow the reader to review the previous discussion of this subject (Shtherland, 1991) .1 Active oxygen in oxidative stress Active oxygen is typically plant cell chloroplast, mitochondria, and other cellular spaces that contain oxidases that act during the redox process , Which is produced by the low level electron transfer.In the oxidative burst phase, the molecular oxygen firstly reduces to form the superoxide ion (O_2 ~ -), then the O_2 ~ - spontaneously disproportionates to form H_2O_2 in the aqueous solution.The reaction is as follows:
