Analysis of self-compatibility genes by mRNA differential display technique and inheritance of self-compatibility in E.sativa Mill
摘要
Abstract
18 hybridized combinations were made between 8 self-compatible lines and 4 self-incompatible lines, and inheritance of self-compatibility in E. Sativa Mill was analysed. Furthermore, expresstion tissue of self-compatible genes was preliminary analysed, and specific cDNA fragments related to self-compatibility were isolated and screened by using mRNA differential display technique. The results showed that all the F1 plants were self-incompatible, and the F2 and BC1 population segregated in ratio. Through chi square test, the segregation ratios of self-incompatibility to self-compatibility in F2 and BC| population were coincided with the ratio of 1:3 and 1:1, respectively. Therefore, it was inferred that the hereditary of self-compatibility in Yunjie was controlled by one pair recessive nucleus gene. Self-compatible genes of Yunjie was not constitutive expression, but that belonged to specific tissue expression. Self-compatible lines had 3 differentially expressed bands which exhibited stably with different primers, these cDNA bands were closely related to self-compatibility of Yunjie.关键词
