摘 要: | 微卫星DNA是重复单位少于6个核苷酸的简单重复序列。在大部分真核细胞的基因组中有着广泛分布,呈孟德尔式遗传。以此为基础发展起来的SSR标记是一种共显性分子标记,遗传多态性丰富。本文着重介绍近年来SSR技术应用在大豆遗传图谱构建、基因研究、品种鉴定和分子标记辅助育种等方面取得的进展,并初步预测该方法在大豆研究中的发展方向。

Abstract: | Microsatellite DNA can be defined as relatively short runs of tandemly repeated DNA with repeat lengths of 6 bp or less. It is widely distributed in most eukaryotic genomes, following Mendelian inheritance. The SSRs are multiallelic codominant genetic markers. This paper reviewed the progress of the marker applied to genome mapping, gene analysis, genotype identification and marker_assisted selection in soybean breeding in recent years, meanwhile, the author predicted the future development of this technology in soybean research. |
