水稻Wx 基因的等位变异及育种利用研究进展
Progress in the Allelic Variation of Wx Gene and Its Application in Rice Breeding
摘要
Abstract
The amylose content in endosperm is considered as the most important determinant influencing rice cooking and eating quality,and is quite different among rice cultivars.The Waxy (Wx )gene,controlling the synthesis of amylose in endosperm,is the major locus affecting rice quality.Up to now,several important Wx alleles had been identified,includingWx a ,Wx b ,wx ,Wx op ,Wx in ,Wx mq ,Wx mp andWx hp ,which might be the main reason for the wide diversity of rice grain quality.We reviewed the mainWx alleles and their effects on rice quality,as well as their application in rice breeding.Finally,the research perspective focusing on riceWx gene is also discussed.关键词
