摘要: 为了寻找线虫生殖相关基因,为开发线虫生殖抑制药剂提供理论基础,通过分析水稻干尖线虫转录组文库高通量测序数据,对Unigene进行KEGG路径分析,筛选出一个孕酮介导的卵母细胞形成代谢路径(progesterone-mediated oocyte maturation),并筛选出该路径的主要调控基因——锌指蛋白基因。通过同源序列比对发现水稻干尖线虫锌指蛋白氨基酸序列中含有核酸结合保守结构域NLS,进一步通过三维结构分析及分子对接验证该蛋白可与DNA分子结合。结果表明,水稻干尖线虫锌指蛋白可与其调控基因的启动子结合从而完成对孕酮介导的卵母细胞形成代谢路径的调控。通过本研究得出最终结论,水稻干尖线虫锌指蛋白具有生物防治价值,值得深入研究。

Abstract: To find the gene which can influence nematode breeding, the zinc finger protein gene was cloned, based on the analysis of the transcriptome of Aphelenchoides besseyi and the study of KEGG pathway. This study is the theoretical basis for the development of nematicide. By the method of homology alignment, the results indicated that the zinc finger protein had a NLS motif. The protein 3D structure study and docking analysis indicated that this protein could regulate the progesterone-mediated oocyte maturation pathway by combining with the promoter of the target gene. The results showed that the zinc finger protein gene was a potential biological control target gene, and worthy of further study.
