利用ISSR和SSR分子标记构建北柴胡遗传图谱

Construction of genetic linkage map of Bupleurum chinense DC. using ISSR and SSR markers

  • 摘要:

    以北柴胡 (Bupleurum chinense DC.) 种内杂交所得的F196株植株为作图群体, 利用拟测交理论, 进行北柴胡遗传图谱构建。经父母本多态性筛选, 30ISSR (inter-simple sequence repeat, 内部简单重复序列) 44SSR (simple sequence repeat, 简单重复序列) 引物中筛选出28ISSR14SSR多态性引物。对F1代进行基因型和连锁分析, 初步构建了包含13个连锁群、80 (72ISSR8SSR) 位点的首张北柴胡遗传图谱。该图谱覆盖长度2 633.9 cM, 平均图距33.4 cM, 13个连锁群包含231个标记不等, 连锁群遗传距离15.41 295.7 cM。该图谱为北柴胡性状基因定位、图位克隆以及分子标记辅助选择育种等研究奠定了基础。

     

    Abstract:

    Molecular genetic map is a fundamental organizational tool for genomic research.  However, a genetic linkage map for Bupleurum chinense DC. has not been developed.  In this study, with the theory of pseudo-testcross, 96 F1 plants from an intraspecific cross of B. chinense were used as mapping populations.  Twenty eight ISSR (inter-simple sequence repeat) primers and 44 SSR (simple sequence repeat) primers were used to detect the polymorphisms between the parental plants, and of them, 28 ISSRs and 14 SSRs were selected to analyze the F1 populations.  The map consisted of 13 linkage groups which included 80 (72 ISSRs and 8 SSRs) loci, and covered 2 633.9 cM with an average density of 33.4 cM.  All 13 linkage groups consisted of 2 − 31 loci ranging in length from 15.4 − 1 295.7 cM.  This map will provide a basis for studies on gene mapping, map-based cloning and maker-assisted selection of important traits in B. chinense.
