摘要 为了研究红莲型细胞质雄性不育与线粒体基因组的关系 ,以水稻红莲型粤泰细胞质雄性不育系 A和保持系 B及杂种一代 F1 为材料 ,应用 AP- PCR分析 ,用 10个单引物对其线粒体 DNA进行扩增。实验结果表明 ,不同的引物在 3种材料间均有不同程度的差异 ,为红莲型细胞质雄性不育分子机理的研究提供了线索 ;此外 ,在引物 6 F1的扩增图谱中找到一条在 YTA和 F1 中特异的带 TAF6 F 2 ,Sounthern分析 TAF6 F2 不育胞质的特异性 ,可能与红莲型水稻细胞质雄性不育性状的形成有关。 An economic and efficient DNA polymorphism assay,AP-PCR,was adopted to Honglian type rice mitochondrial DNA.The result indicated obvious differences in the mt-DNA of CMS line,maintain line and its hybrid,which could further the research of CMS mechanism.Through the comparation of fingerprints among the materials,a CMS line specific mt-DNA band TAF 6F2 was isolated.Southern Blot showed it only existed in the mt-DNA of CMS line and the first generation hybrid.This band may be relative to the formation of CMS in Honglain type rice.
