棉籽蛋白与油分含量的遗传基础与QTL定位研究进展
Research progress on the genetic basis and QTL mapping of cottonseed protein and oil content
摘要
Abstract
Cotton is an important economic crop in the world,occupying a significant position in the national economy.Cottonseed,as the main product of cotton production,is rich in high-quality protein and oil.Against the backdrop of the current shortage of protein and oil resources,fully exploring and utilizing the protein and oil resources in cottonseed can ensure the safety of edible oil supply and alleviate food security issues.With the increasing attention paid to the comprehensive utilization of cottonseed,the research on the genetic improvement of cottonseed nutritional quality is gradually increasing.This review provides an overview of the common methods for determining cottonseed protein and oil content,and summarizes the genetic characteristics and influencing factors of these traits.The relationships among cottonseed protein and oil content and fiber yield as well as the fiber quality traits were analyzed.A total of 335 quantitative trait locus(QTL)for oil content and 196 QTL for protein content were collected to construct a consistent physical map.In addition,the research progress of cottonseed protein and oil related synthetic pathways and regulatory genes were introduced,and the future research directions of biological breeding for cottonseed nutritional quality was prospected,which can provide a reference for the genetic improvement of nutritional quality in cottonseed.关键词
