水稻产量与淀粉品质协同调控的分子遗传研究进展OA

High yield and quality are two major goals in rice breeding programs.The key challenges facing breeding and functional genomics research in rice are the compatible improvement of both grain yield and quality.This work provides a comprehensive review of the advances in molecular genetic research on the co-regulation of grain yield and starch quality in rice.We summarize the genetic regulation of starch synthesis,scrutinize the molecular mechanisms of grain yield,examine the molecular mechanisms of co-regulation,and investigate the cloning and functional analysis of genes related to grain yield and quality.New approaches are proposed to address the trade-off between grain yield and quality,based on the discussion of previous research.The information will be valuable in overcoming the challenges related to grain yield and quality in rice using molecular breeding technology and will greatly facilitate the development of super rice varieties with high yield and good quality.
