Abstract

The main goals of rice breeding nowadays include increasing yield, improving grain quality, and promoting complete mechanized production to save labor costs. Rice grain shape, specified by three dimensions, including grain length, width and thickness, has a more precise meaning than grain size, contributing to grain appearance quality as well as grain weight and thus yield. Furthermore, the divergence of grain shape characters could be utilized in mechanical seed sorting in hybrid rice breeding systems, which has been succeeded in utilizing heterosis to achieve substantial increase in rice yield in the past decades. Several signaling pathways that regulate rice grain shape have been elucidated, including G protein signaling, ubiquitination-related pathway, mitogen-activated protein kinase signaling, phytohormone biosynthesis and signaling, microRNA process, and some other transcriptional regulatory pathways and regulators. This review summarized the recent progress on molecular mechanisms underlying rice grain shape determination and the potential of major genes in future breeding applications.

谷粒形状基因:塑造水稻育种的未来
目前水稻育种的主要目标是提高产量,改善粮食品质,促进完全机械化生产,以节省劳动力成本。米粒形状是由粒长、粒宽、粒厚三个维度来定义的,它比粒大小具有更精确的含义,不仅影响籽粒的外观质量,还影响籽粒的重量,从而影响产量。此外,在杂交水稻育种系统中,可以利用籽粒形状性状的差异进行机械分选,在过去几十年里成功地利用杂种优势实现了水稻产量的大幅提高。目前已经阐明了几种调控水稻籽粒形状的信号通路,包括G蛋白信号通路、泛素化相关信号通路、丝裂原激活的蛋白激酶信号通路、植物激素生物合成和信号通路、microRNA过程以及其他一些转录调控通路和调控因子。本文综述了水稻籽粒形状决定的分子机制及主要基因在水稻育种中的应用前景。
