| 摘 要： | 利用GLM模型对12个表达序列标签(expressed sequence tag,EST)标记的基因型与鲤耐低温性状进行相关性分析,然后使用OneMap软件将这些EST标记进行连锁定位研究,并通过Blast x搜索引擎对这些候选EST进行注释。结果显示,EST标记CC009(P<0.05)和CC115(P<0.01)与鲤鱼耐低温性状显著相关;12个EST标记中有8个标记分别连锁定位到6个连锁群中,其中与耐低温相关的CC009和CC115分别定位到鲤连锁图谱的第38号连锁群和第2号连锁群;蛋白质数据库同源性比对发现,CC009与斑马鱼(Danio rerio)尿嘧啶激酶1(uridine-cytidine kinaseI)的同源性高达94%;而CC115为原绿球藻(Prochlorococcus marinus str)的假定糖基转移酶(putative glycosyl transferase)的同源性为56%。

| Abstract: | Expressed sequence tags (ESTs) are parts of complementary DNAs (cDNAs) with certain gene function.It provides us more information than other neutral markers. The association of EST markers with phenotypes can increase our understanding of the biochemical pathways and mechanisms affecting economically important traits. In this study, 12 candidate EST markers isolated from the cold-induced brain cDNA of common carp (Cyprinus carpio L.) were conducted the correlation analysis of marker and cold tolerance trait... |
