水稻籽粒灌浆的影响因素及相关基因和蛋白研究进展

Research Progress on Influence Factors of Rice Grain Filling and its Related Genes and Proteins

籽粒灌浆是决定水稻产量和品质的关键步骤,直接关系着水稻的结实率和千粒重。水稻籽粒灌浆受到多种因素影响,包括品种自身特性、植物激素以及环境因子等。在分子水平上,水稻灌浆也受淀粉合成与运输相关酶及基因的调控。本文综述了水稻籽粒灌浆的影响因素及其相关基因和蛋白的研究进展。

Grain filling is a key step in determining the yield potential and grain quality of rice, which is directly related to the seed setting rate and 1 000-grain weights. Rice grain filling is influenced by many factors, including the inherent characteristics of rice cultivar, plant hormones and environmental factors. At the molecular level, grain filling is also regulated by the related enzymes and genes during starch synthesis and transportation. Research progress on influence factors and related proteins and genes of rice grain filling were reviewed in the paper.
