| 摘 要： | 水稻的小孢子母细胞在花粉囊中进行减数分裂产生小孢子，小孢子进一步发育成花粉粒。当花粉成熟时，花粉粒从花粉囊中释放出来进行受精。分子生物学的研究已经发现了一些参与这一过程的基因，包括控制花粉囊组织的分化、小孢子母细胞的减数分裂、小孢子的发育和花药的开裂等。本文旨在总结水稻花粉发育过程及其调控分子机制的研究进展。

| Abstract: | Within the rice anther, meiosis of the pollen mother cell produces microspores, which further develop into pollen grains. Then the mature pollen is released from the dehiscesd anther, and pollination occurs. Molecular studies have identified some genes participating in this process, including those regulating anther cell division and differentiation, controlling male meiosis, supporting pollen development, and promoting anther dehiscence. The rice pollen development process and its molecular mechanisms are reviewed in this article. |
