In living organisms, sexual reproduction relies on the successful development of the gametes. Flowering plants produce gametes in the specialized organs of the flower, the gametophytes. The female gametophyte (FG), a multicellular structure containing female gametes (egg cell and central cell), is often referred to as an embryo sac. Intriguingly, several protein complexes, molecular and genetic mechanisms participate and tightly regulate the female gametophyte development. Recent evidence indicates that small RNA (sRNA) mediated pathways play vital roles in female gametophyte development and specification. Here, we present an insight into our understanding and the recent updates on the molecular mechanism of different players of small RNA-directed regulatory pathways during ovule formation and growth.
在生物体中，有性生殖依赖于配子的成功发育。开花植物在花的专门器官——配子体中产生配子。雌性配子体（FG）是一种含有雌性配子（卵细胞和中央细胞）的多细胞结构，通常被称为胚囊。有趣的是，有几个蛋白质复合物、分子和遗传机制参与并严格调节雌性配子体的发育。最近的证据表明，小 RNA（sRNA）介导的途径在雌性配子体发育和特化中起着至关重要的作用。在这里，我们介绍了对小 RNA 导向调控途径的不同参与者在胚珠形成和生长过程中的分子机制的理解和最新进展。
