摘要:

阐明植物雄配子体与雌配子体互作的分子机理一直是植物有性生殖研究的前沿和热点。但限于研究难度较大, 很多重要科学问题仍有待回答。关于花粉管如何感知雌配子体信号从而定向生长进入胚囊以投送精细胞就是悬疑多年的问题之一。最近, 中国科学家在解析雄配子体感知雌配子体引导信号的分子机制方面取得了突破性进展。

Abstract:

The investigations on molecular mechanism of male and female gametophyte interaction have been a hot topic and frontier in the field of sexual plant reproduction. However, due to the great difficulties, many essential questions still remain to be answered. How does the pollen tubes sense the signals from female gametophyte is one of the suspense questions. Recently, Chinese scientists have presented a clear answer to the question and open a new window to seek the mechanism that regulates male gametophyte response to the female gametophyte and ensures successful fertilization.
