玉米单向异交不亲和基因是一种配子体基因(Gametophyte factors,Ga)。Ga基因是影响单倍体配子有性传递的遗传因子,许多带有Ga基因的爆裂玉米可以给不带有Ga基因的马齿型和硬粒型玉米正常授粉结实,反交则通常不结实。Ga基因的这种特性在生产上可以用于特用玉米与普通玉米以及非转基因玉米与转基因玉米之间的生殖隔离,在基础理论上可以用于研究玉米授精过程中的基因互作、信号传导以及雌雄配子间的不亲和机理。
Maize unidirectional disjoint incompatibility gene is a gametophyte gene (Ga). Ga gene is a genetic factor affecting the sexual transmission of haploid gametes. Many burst corn with Ga gene can pollinate normal and durum type maize without Ga gene normally. This property of Ga gene can be used in production to reproductive isolation between special maize and normal maize, non-GM maize and GM maize, and can be used in basic theory to study gene interaction and signal transduction in maize insemination As well as the male and female gametes between the mechanism of incompatibility.
