摘要:
水稻是全球主要的粮食作物之一，水稻产量对于保障粮食安全具有至关重要的意义。有效穗数、每穗粒数以及千粒重影响着水稻的产量，千粒重受粒型特征的制约。籽粒长度、宽度、厚度以及长宽比是描绘粒型特征的关键参数。迄今，已有600余个控制水稻籽粒性状的QTL被定位，200余个基因被克隆，粒型遗传调节机制涵盖了泛素-蛋白酶体途径、激素信号途径、G蛋白信号途径、丝裂原活化蛋白激酶(MAPK)信号途径、转录因子以及表观遗传学修饰等众多的调节途径。它们之间存在着交互作用，组成了水稻粒型的调控网络。粒型调控网络极其复杂，多数基因上下游的调控机制尚不清楚。发掘更多粒型调控基因，并解析已知粒型调控基因的上、下游元件，对各调控通路间的潜在关联进行阐明，从而进一步完善水稻粒型调控网络，这将是今后研究工作面临的一个重要课题。通过组合不同的粒型调控基因，实现对目标性状的改良，从而获得不同类型的符合人们需求的水稻品种，以适应市场和环境的需要，是粒型基因在育种应用中的发展趋势。本文对粒型调控网络和相关基因进行了总结和梳理，阐明其在育种上的应用前景，旨在进一步加深对水稻籽粒发育调控分子机制的理解，为培育高产优质品种奠定基础。
