摘要
The low-molecular-weight glutenin subunits（LMW-GS）account for 40% of gross glutenins of wheat,usually used as a major indicator for wheat quality improvement.Here,I comprehensively reviewed the advances in LMW-GS from their classification,coding gene loci on chromosomes and structural features,polypeptide chains composition,gene sequences accessed in Genbank,molecular markers saturation level,and their impacts on wheat process quality,in order to provide a theoretical basis for the utilization of LMW-GS in genetic improvement of wheat quality.
低分子量麦谷蛋白(LMW-GS)占总的小麦谷蛋白的40%,是小麦品质改良的主要目标之一。就LMW-GS的分类、LMW-GS编码基因染色体位点及结构特点、LMW-GS多肽链组成、Genbank注册的基因及分子标记的开发、不同LMW-GS对加工品质的影响等几个方面进行了系统论述,为低分子量麦谷蛋白亚基用于小麦品质改良提供了理论基础。
