Web甘蓝作为典型的异花授粉作物，具有花期自交不亲和的特性，属于孢子体自交不亲和性植物（sporophytic SI，SSI）（Tantikanjana et al.，2010）。自交不亲和系在遗传上由多个复等位基因高度多态性的S位点控制（Takasaki et al.，2000）。 WebA second type, gametophytic self-incompatibility, involves the inability of the gametes from the same parent plant to fuse and form a zygote or, if the zygote forms, then it fails to develop. These systems force outcrossing and maintain a wide genetic diversity.
WebSelf-pollination showed typical sporophytic self-incompatibility characteristics, with the rare pollen swelling at the pollen tube apex. In contrast, cross-pollination was characterized by pollen germination and penetration of the stigma by the growing pollen tubes. RNA-Seq was used to profile gene expression in the floret tissue during self ...
