Abstract:

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.
