摘要
植物生殖发育过程直接影响许多重要农作物的产量。雄性发育与减数分裂为植物生殖发育过程中的重要过程,对其调控机理的研究不仅有助于理解生殖发育的分子机制,也可以为农作物的遗传育种提供理论依据。近些年来,我国科学家在此领域取得了一系列高水平的研究成果,主要包括植物花药中关键细胞的命运决定、绒毡层细胞和小孢子发生的分子机制、减数分裂同源染色体相互作用的分子机理和花粉萌发及伸长的基因调控等等。本文对我国科学家所取得的诸多成就进行了简要的回顾,并提出了对该领域发展的一些思考和看法。
Plant reproductive development can directly impact productivity of agricultural crops. Male development and meiosis are crucial processes in plant reproductive development, so analysis of their regulation not only can help understanding the molecular mechanisms underly-ing reproductive development, but also provide theoreti-cal basis for crop breeding. In recent years, Chinese scientists have made important achievements in this are-a, including cell fate determination, molecular mecha-nisms for tapetum cell and microspore formation, meiot-ic chromosome interactions, and regulation of pollen germination and pollen tube growth. This article briefly summarizes the findings of Chinese scientists and pres-ents some consideration for for future advances.
