玉米籽粒淀粉生物合成及调控因素研究进展
Research Progress in Starch Biosynthesis and Regulatory Factors in Maize Kernel
摘要
Abstract
Maize,as a widely cultivated crop worldwide,is not only an indispensable food source in the human diet,but also plays an important role in the feed industry and clean energy.The starch rich in its kernels constitutes the main body of maize biomass and directly determines the yield level of maize.It is an indispensable raw material in agricultural production and food processing.However,with the continuous growth of the global population,the acceleration of urbanization,and the reduction of agricultural land and frequent natural disasters caused by climate change,the global food supply system is facing unprecedented challenges.As important crops in the world,it is very crtical to cultivate high-yield varieties by analyzing its starch biosynthesis pathway.This paper summarizes the key enzymes and transporters involved in the maize starch biosynthesis pathway and discusses the specific roles of these factors in the process of starch synthesis.Concurrently,this paper reviews the grain phenotypes of mutants of key enzymes in the synthesis pathway,and analyze the effects of gene mutations on starch yield and quality.In addition,this paper also summarizes the various factors regulating starch biosynthesis and discusses how to improve the yield and quality of maize by optimizing these factors.Finally,this paper looks forward to the future research direction,aiming to provide a solid theoretical basis and practical guidance for molecular design breeding of high quality and high yield maize.关键词
