小RNA的长度为20-24个核苷酸。在植物中，小RNA根据其生物发生和分子特征分为microRNA（miRNAs）和小干扰RNA（siRNAs）。与小RNA在孢子体组织中的作用的广泛知识相反，小RNA在配子体细胞中的分布和功能的研究较少。然而，随着单细胞分选和RNA测序技术的改进，小RNA，特别是siRNA，在精子细胞和营养细胞之间的分布，以及精子传递的小RNA在早期种子发育中的功能已被阐明。本文综述了近5年来拟南芥雄配子中小分子RNA的研究进展，着重介绍了小分子RNA在拟南芥细胞间的通讯及其生物学意义。
Small RNAs are 20-24 nucleotides in length. In plants, small RNAs are classified into microRNAs (miRNAs) and small interfering RNAs (siRNAs), based on their biogenesis and molecular features. In contrast to the extensive knowledge of the roles of small RNAs in sporophytic tissues, the distribution and function of small RNAs in gametophytic cells have been less well studied. However, with the improvement of single-cell sorting and RNA sequencing technologies, the distribution of small RNAs, especially siRNAs, between sperm cells and the vegetative cell, as well as the function of sperm-delivered small RNAs during early seed development have been elucidated. This review summarizes work from the past 5 years regarding small RNAs in male gametes, emphasizing the intercellular communication and biological significance of small RNAs in Arabidopsis.
