| 摘 要： | 基因拷贝数变异(CNVs)是引起大豆品种对胞囊线虫抗性差异的因素之一,以抗大豆胞囊线虫病种质东农L~(-1)0以及感病种质黑农37、绥农10和绥农14为试验材料,利用实时荧光定量PCR法对大豆胞囊线虫抗性QTL位点qscn3-3内27个编码基因进行拷贝数变异分析,F测验表明15个目的基因在不同品种间存在拷贝数变异;抗感病品种PCR产物丰度相对值分析结果表明9个目的基因拷贝数在抗感病种质间存在显著的差异,推测其功能是通过编码抗病蛋白和富亮氨酸蛋白来实现大豆对大豆胞囊线虫相关抗性。

| Abstract: | Gene copy number variants (CNVs) can cause the difference in soybean resistance to soybean cyst nematode (SCN).In this study,four soybean germplasms including Dongnong L-10(resistant to SCN),Heinong 37,Suinong 10 and Suinong 14 (susceptible to SCN) were selected to analyze the CNVs of 27 genes in the genomic region of SCN resistance related quantitative trait loci(QTL) ‘ qscn3-3’ using the method of real-time quantitative PCR.The result of F test showed that the copy number of 15 genes were different among four soybean germplasms.A total of 9 genes showed significant difference in copy number between Dongnong L-10 and the other three susceptible germplasms.It was speculated that its function was accomplished by coding disease-resistant protein and leucine rich protein for SCN resistance. |
