摘要:

以甜樱桃‘红灯’为试材, 应用选择性扩增微卫星( SAM) 法分离、克隆了100个SSR序
列, 其中81个非重复, 可用。加上搜索数据库所获得的1个SSR序列, 一共82个序列用于特异引物的设计。仅从69个序列的77个基因座设计出特异引物。合成38对特异引物, 对其中的36个基因座进行检测。其中19对引物扩增出相应大小的片段, 另外8对引物扩增出非预期片段。最后, 以27个甜樱桃种质的基因组DNA为模板, 从27对可扩增出带的引物中, 筛选出多态性引物24对, 获得了24个甜樱桃基因座特异性SSR标记。

Abstract: A total of 100 sequenceswere isolated and cloned by SAM ( SelectivelyAmp li2
fiedMicrosatellite) and another one was obtained from the NCBI and EMBL databases. 82 SSR sequenceswere used to design the special primers at 77 loci from 69 fragments. Thirty-eight pairs of special primerswere synthesized, matchingwith 5′anchored degenerate SSR p rimer, to detect 36 SSR loci. 27 p rimer pairs amp lified clear and robust DNA fragment, of which nineteen pairs of SSR p rimers amp lified the corresponding SSR sequences and eight amplified the unexpected fragments. 24 polymorphic p rimer pairs were selected from the 27 p rimer pairs by using the genomic DNA of 27 sweet cherry germp lasm, and 24 locus-specific SSR markerswere obtained.
