摘 要:

作为具有生命活力的植物幼体, 种子是植物特有的繁殖器官和植物生长发育的前提。种子大小是备受关注的农艺性状, 也是影响作物产量的关键因素之一。近年来, 随着种子大小调控机制研究工作的不断深入, 已鉴定出许多种子大小调控相关的基因。植物激素和microRNA (miRNA)在调节种子发育、大小、质量以及作物产量方面发挥着至关重要的作用。本文概述了植物激素与miRNA对植物种子大小和发育的调控作用及其分子机制, 为研究人员开展相关研究提供参考。

Abstract:

Seed is the specifc reproductive organ of plants and is vital for plant growth and development. Seed size is an important agronomic character in agricultural production and a key factor affecting crop yield. During recent years, the regulation mechanism of seed size has been well studied, and many genes regulating seed size and related regulatory pathways have been identifed. Plant hormone and microRNA (miRNA) play an extremely important role in regulating seed development, seed size, seed weight and crop yield. In this paper, the molecular mechanisms of plant hormone and miRNA regulating plant seed development and seed size are summarized, which provides a molecular understanding for the mechanisms regulating seed size and development, and a useful reference for researchers to carry out related work in the future.

Key words: seed size; seed development; hormone regulation; microRNA regulation
