雌配子体在被子植物有性生殖中起着重要作用。我们以前分离的maa3(magatama3)突变体的拟南芥,有缺陷的雌配子体的发展,珠孔花粉管的指导,并防止吸引多个花粉管。我们观察到极核的核仁很小,授粉时极核往往不融合。MAA3基因编码RNA代谢所需的酵母Sen1解旋酶的同源物。这表明,MAA3可能调节RNA分子负责核仁组织和花粉管引导。
The female gametophyte plays a central role in the sexual reproduction of angiosperms. We previously isolated the maa3 (magatama3) mutant of Arabidopsis thaliana, defective in development of the female gametophyte, micropylar pollen tube guidance, and preventing the attraction of multiple pollen tubes. We here observed that the nucleolus of polar nuclei is small, and that the fusion of polar nuclei often did not occur at the time of pollination. The MAA3 gene encodes a homolog of yeast Sen1 helicase, required for RNA metabolism. It is suggested that MAA3 may regulate RNA molecules responsible for nucleolar organization and pollen tube guidance.
