简介：表示顺序标注的普通鲤鱼(EST)为存在ofmicrosatellites，或简单顺序重复(SSR)被分析。在NCBIdbEST数据库，10612sequences的一个总数在2004年12月31日前被登记。2-6nucleotidemicrosatellites的完全的搜索导致了513包含SSREST的鉴定，为4.8%总数的财务。聚合分析显示包含SSREST的73个序列掉进27个组并且留下440EST是独立的。467唯一的包含SSREST的一个总数被识别。这些EST-SSRs包含了许多简单顺序类型，并且di-nucleotiderepeats和tri-nucleotiderepeats是最丰富的，为42.1%全部和27.9%的财务分别地。thedinucleotide重复，CA/TG是最丰富的，由GA/TC列在后面。BLASTx搜索证明SSRloci的that38.1%能与基因或蛋白质被联系知道或包含SSREST的未知function.BLASTx搜索也在zebrafishsequences上显示出点击的高频率(98/179)。
