摘要
介绍了草酸氧化酶的发现过程、组成与结构;阐述了该酶的生物功能,即在植物中能将草酸降解成H2O2和CO2,从而消除草酸毒素的致病作用;综述了前人对该酶进行的基因克隆与遗传转化方面的研究,结果表明遗传转化可提高植物体内的草酸氧化酶含量,并增强植物抗性。提出了现有研究中存在基因资源少、异源转化困难等问题,今后的研究重点应放在发掘与该酶相关的植物资源和筛选较抗(耐)病品种,以期为今后的研究提供全面的信息和参考。
Introduced the discovery process, composition and structure of Oxalate oxidase (oxilate oxidase, oxo); discussed the biological function of the enzyme, namely, can degrade to H2O2 and CO2, thereby eliminated the pathogenicity of toxin. Overviewed the studies of gene cloning and genetic transformation of OXO, the results showed that the genetic transformation can improve content of OXO, and enhance plant resistance. Proposed the genetic resources of OXO were limited, and heterologous gene were hard to transformate. For the future, the emphases should be the discovery of resistant plant resources, in order to offer the comprehensive information for the research on the gene.
