为红鱼制作了匿名和与基因相连的微卫星遗传连锁图谱，红鱼是一种重要的经济鱼类，为加强恢复和商业食用鱼生产而养殖。该图谱由486个微卫星组成(440个匿名微卫星，46个基因连锁)，跨越24条单倍体红鼓染色体对应的24个连锁群。产生的连锁图谱被用来确定红鼓和其他四个可获得基因组组合的外胚种之间共享同步性的区域。在红鼓和所有四个比较物种之间观察到了相当大的共性，并利用基于共性的作图方法在红鼓基因组中定位了另外80个基因和单态的、基因连锁的微卫星。该遗传连锁图谱将为红鱼养殖提供有价值的资源，特别是用于候选基因定位和定位数量性状基因座的方法。(C)2014爱思唯尔B.V.保留所有权利。
A genetic linkage map of anonymous and gene-linked microsatellites was generated for red drum, an economically important sciaenid fish cultured for both restoration enhancement and commercial food-fish production. The consensus map, based on linkage data combined from two full-sib families, consisted of 486 total microsatellites (440 anonymous, 46 gene-linked), and spanned 24 linkage groups corresponding to the 24 (haploid) red drum chromosomes. The linkage map generated was used to identify regions of shared synteny between red drum and four other percomorph species for which genome assemblies are available. Considerable synteny was observed between red drum and all four comparison species, and a synteny-based mapping approach was used to putatively localize an additional 80 genes and monomorphic, gene-linked microsatellites within the red drum genome. The genetic linkage map will be a valuable resource for red drum aquaculture, particularly for candidate-gene approaches to identify and map quantitative trait loci. (C) 2014 Elsevier B.V.
