Single radial immunodiffusion was used to study the self-incompatibility (S) proteins present in stigmas of two inbred lines of Brassica oleracea: a self-incompatible line and a self-compatible mutant derived from it. The genetic basis of observed quantitative differences in S proteins between the two inbreds was shown to be determined by a single gene with dosage effects. Self-pollination of individual plants with high, intermediate and low levels of S protein in the stigmas, respectively, resulted in low, intermediate and high seed set.
采用单向辐射免疫扩散法研究了甘蓝两个自交系柱头中存在的自交不亲和(S)蛋白:一个自交不亲和系和由其衍生的一个自交亲和突变体。结果表明,两个自交系之间观察到的S蛋白定量差异的遗传基础由一个具有剂量效应的单基因决定。分别对柱头中S蛋白水平高、中、低的单株进行自花授粉,结果结实率分别为低、中、高。
