A second‐generation genetic linkage map for bighead carp (Aristichthys nobilis) based on microsatellite markers

Abstract: SummaryBighead carp (Aristichthys nobilis) is an important aquaculture fish worldwide. Genetic linkage maps for the species were previously reported, but map resolution remained to be improved. In this study, a second-generation genetic linkage map was constructed for bighead carp through a pseudo-testcross strategy using interspecific hybrids between bighead carp and silver carp. Of the 754 microsatellites genotyped in two interspecific mapping families (with 77 progenies for each family), 659 markers were as… Show more

“…A second-generation linkage map of bighead carp has been constructed recently (Zhu et al 2014), using 659 polymorphic microsatellites which were mainly developed from bighead carp and silver carp genomes. The flanking sequences (with an average length of about 2,000 bp) of the 659 microsatellites were used for sequence homology searches against the genomes of five model fishes (zebrafish, medaka, fugu, tetraodon and three-spined stickleback) and four food fishes (Nile tilapia, common carp, grass carp and silver carp) using BLASTn under default settings in NCBI.…”

“…Of the total 486 loci (data not shown) with significant hits against at least one of the five model fish genomes, 4 (0.8 %) matched all five species, 6 (1.2 %) matched four species, 20 (4.1 %) matched three species, and 50 (10.3 %) (Zhu et al 2014) in genomes of zebrafish, tetraodon, medaka, three-spined stickleback, fugu, common carp, Nile tilapia, silver carp and grass carp and their phylogenetic relationship based on COII sequences. The neighborjoining tree of the species analyzed in this study was constructed through the software Mega 4.0 with a bootstrap of ×10,000, and COII sequences of silver carp (FJ827138.1), bighead carp (FJ827140.1), grass carp (NC_018134.1), common carp (FJ655382.1), zebrafish (NC_002333.2), medaka (NC_012975.1), three-spined stickleback (AP002944.1), Nile tilapia (NC_013663.1), fugu (AJ421455.1), tetraodon (AP006046.1) and human (NC_012920.1) were downloaded from NCBI matched two species; in other words, 80 of the 486 loci (16.5 %) matched at least two model fishes.…”

“…However, natural populations of bighead carp have seriously declined during recent decades due to ongoing human activities such as overfishing and pollution. Worse still, unscientific artificial releasing and frequent flooding may lead to a mixture of natural and cultured individuals, which has resulted in in-breeding depression and reduction of growth performance (Liu et al, 1997;Zhu et al, 2014). Furthermore, the traditional selective breeding program is inefficient in bighead carp because of its relatively long generation interval (about 4-5 years).…”

“…Hence, it's necessary to deploy MAS program and accelerate the breeding program for bighead carp. Although some genetic and genomic resources have been developed in bighead carp, such as microsatellite markers Guo et al, 2013a;Zhu et al, 2013a), the first and second generation genetic linkage map (Liao et al, 2007;Zhu et al, 2014), microsatellite-centromere mapping and comparative genomics , the genetic architecture of economic traits remains unknown.…”
