Understanding the behavior of pollen during pollination is important for food security in the future. The elucidation of pollen development and growth regulation largely relies on the study of the dicotyledonous model plant Arabidopsis thaliana. However, rice (Oryza sativa) pollen exhibits different characteristics to that of Arabidopsis. The latter undergoes programmed dehydration and withstands adverse environmental conditions, whereas rice pollen is sensitive to desiccation. Moreover, the short longevity of rice pollen significantly hampers hybrid seed production. Although the “omics” data for mature rice pollen have been accumulated, few genes that control pollination and pollen hydration have been identified. Therefore, to facilitate future studies, it is necessary to summarize the developmental processes involved in pollen production in rice and to consolidate the underlying mechanisms discovered in previous studies. In this review, we describe the pollen developmental processes and introduce gametophytic mutants, which form defective pollen in Arabidopsis and rice. In addition, we discuss the perspectives on the research on pollen longevity, adhesion and hydration.

水稻和拟南芥成功施肥的第一步：花粉寿命，附着力和水合作用。

了解授粉过程中的花粉行为对于将来的粮食安全至关重要。对花粉发育和生长调节的阐明很大程度上取决于对双子叶模式植物拟南芥的研究。然而，水稻（Oryza sativa）花粉表现出与拟南芥不同的特性。。后者经过程序性脱水并能承受不利的环境条件，而大米花粉对干燥很敏感。此外，水稻花粉的短寿命显着阻碍了杂交种子的生产。尽管已经积累了成熟水稻花粉的“组学”数据，但几乎没有发现控制授粉和花粉水合作用的基因。因此，为了便于将来的研究，有必要总结水稻花粉生产中涉及的发育过程，并巩固先前研究中发现的潜在机制。在这篇综述中，我们描述了花粉的发育过程并介绍了配子体突变体，它们在拟南芥中形成有缺陷的花粉。和米饭。另外，我们讨论了关于花粉寿命，粘附和水合作用研究的观点。
