新型大白菜细胞质雄性不育系RC7的不育分子机理探讨
0
()
摘要:
用PCR方法在大白菜新型雄性不育系RC7中克隆出与雄性不育基因相关的片段,该片段与NCBI发布的orf138具有高度同源性,同源性为100%。说明RC7的不育机理与Ogu-CMS具有相似性,也证明了CMS基因的相对保守性。为RC7的利用奠定了理论基础,充实了大白菜细胞质雄性不育理论。

Research on molecular mechanism of new Chinese cabbage cytoplasmic male sterility RC7
()
Abstract:
The special sequence related to CMS was amplified in the new Chinese cabbage CMS RC7 by PCR amplifying,and its homology is 100% with orf138 published in NCBI.This not only indicated that RC7 has the similar sterility with Ogu-CMS,but the gene related to CMS is relative conservative.The result both established the theory for full utilization of new variety RC7 and enriched the CMS theory.
Key words:  Chinese cabbage,CMS,orf138
