摘要: 选取家蚕attacin和alpha-amylase基因序列,设计特异性引物,在家蚕品系P50、C108和子一代 (F1) 中扩增。分别采用4种不同的限制性内切酶对扩增产物酶切,最后每个基因都获得了一个CAPs分子标记。依据所得的两个CAPs分子标记对12个品系的家蚕遗传多样性进行了初步研究,构建了其分子系统树。

Abstract: Cleaved amplified polymorphic sequence (CAPs) markers are based on PCR amplification of known genes, cDNA sequences or RAPD sequences. The PCR products are digested by restriction enzymes, generating the simple type of data as heterozygotes and homozygotes. Here we designed primers based on silkworm attacin and alpha-amylase genes,then digested the PCR products in silkworm strains P50, C108 and their progeny F1 using 4 different restriction enzymes respectively. Furthermore,the genetic diversity and phylogenetic relationship of 12 silkworm strains were investigated using the obtained two CAPs markers.
