摘要
甘蓝型油菜波里马细胞质雄性不育与显性细胞核不育受2套完全不同的基因体系控制。如果没有显性上位抑制基因的作用,显性核不育基因在不同的遗传背景中都能够稳定表达。在波里马不育胞质中显性核不育基因抑制核质互作不育基因而表现出显性核不育特性。
Polima cytoplasmic male sterility (Pol CMS) and dominant genic male sterility (DGMS) in rapeseed (Brassica napus L.) are controlled by two independent gene systems. Without the effect of the dominant epistatic inhibition gene (Rf), the dominant male sterile gene (Ms) can be stably expressed in different genetic backgrounds. In Polima male sterile cytoplasm, the Ms gene can inhibit the expression of the CMS gene and, as a result, exhibits the characteristics of DGMS.
