萝卜叶绿体rbc L基因定位及ctDNA基因文库的构建
A VARIANCE ANALYSIS METHOD FOR DETECTING AND ESTIMATING LINKAGE BETWEEN MOLECULAR MARKERS AND QUANTITATIVE TRAIT LOCI
【摘要】 用改进的高离子强度法分离的萝卜叶绿体(ct)经SDS60℃裂解,抽提的ctDNA只需简单纯化即可用于酶切分析.萝卜ctDNA用4种限制性内切酶BamHⅠ,PstⅠ,HindⅢ和EcoRⅠ分别进行单酶完全酶解,推算其分子量和长度分别为82.5×106和125kb.以Nicktranslation标记的异源探针rbcL基因与ctDNAEcoRⅠ片段进行杂交,初步定位在E11片段(1.7kb)上.以BluescriptM13为载体构建了萝卜ctDNAEcoRⅠ基因文库
【Abstract】 The analysis of Variance was proposed to detect and estimate linkage between a marker locus and quantitative trait loci(QTL) in different populations. Linkage of wide compatibility genes in rice was determined to a molecular marker locus using this method.
