为丰富普通荞麦（Fagopyrum esculentum Moench）的序列信息，挖掘有效的 SSR 标记，基于Hiseq 2000测序平台对普通荞麦的种子转录谱进行测序、分析，利用 Misa 软件进行 SSR 位点扫描，采用Primer 5．0引物设计程序对其中的300个 SSR 位点设计引物，随机挑选40对引物对19个普通荞麦品系进行遗传多样性分析。结果表明：测序共产生20508824条高质量的短序列（read），总长度为1889111004 bp，通过拼接最终获得54947条转录本（transcript）和36133个独立基因（unigene）。在2226个独立基因中发现了2666个 SSR 位点。有20对引物（占50％）能扩增出目标产物，其中，12对有多态性，多态性信息量（PIC）范围为0．10～0．93，平均为0．57，多态性程度高。%To enrich sequences information and develop mass SSR marker,the authors used Hiseq2000 to sequence and de novo assemble the seed transcriptome of F.esculentum.SSR motifs were identified using MISA 1.0 software and 300 primer pairs flanking EST-SSR loci were designed using Primer 5.0 software.A total of 20 508 824 high quality reads (total length 1,889,111,004 bp)were obtained comprising 54 947 transcripts and 36 133 unigenes.In total,2 666 SSRs were identified from 2 226 unigenes.Twenty (50%)out of 40 primer pairs selected at random yielded amplification products,of which 12 primer pairs showed polymorphism among 19 different common buckwheat varieties,and the PIC ranged from 0.10 to 0.93 with the mean value of 0.57.
