摘要
棉籽油味道柔和,色泽金黄,在各种食品中起着至关重要的作用.此外,棉籽油因其独特的脂肪酸特性、抗炎和心脏保护特性而备受关注.因此,了解调控棉籽贮藏油生物合成的遗传机制,开展关键基因挖掘,选育高油优质棉花品种具有重要意义.随着高通量测序技术和生物信息学分析工具的快速发展,全基因组测序变得更加简单高效,使得全基因组关联分析技术(GWAS)成为了研究复杂性状的一种核心工具.介绍了GWAS的原理及研究优势,论述GWAS在不同油料作物及棉花性状研究中的应用进展.并对今后棉籽油相关性状的遗传研究提出了一些建议,对存在的问题进行探讨及展望,旨在为今后利用GWAS进行棉籽油性状遗传基础的研究及分子标记辅助育种提供理论依据.
Abstract
Cottonseed oil,soft in taste and golden in color,plays a crucial role in various foods.In addition,cottonseed oil has attracted much attention due to its unique fatty acid properties,anti-inflammatory and heart protective properties.Therefore,it is of great significance to under-stand the genetic mechanism that regulates the biosynthesis of cottonseed storage oil,carry out key gene mining,and select high-quality cotton varieties with high oil content.With the rapid development of high-throughput sequencing technology and bioinformatics analysis tools,whole genome sequencing has become simpler and more efficient,genome-wide association analysis (GWAS) has become a key tool for studying com-plex traits.This paper introduces the principle and research advantages of GWAS,discusses the progress of its application in the research of dif-ferent oil crops and cotton characters.Some suggestions for future genetic studies of cottonseed oil related traits were put forward.The existing problems were discussed and prospected in order to provide a theoretical basis for future studies on the genetic basis of cottonseed oil traits and marker-assisted breeding by GWAS.
