Isolation and characterization of 55 SNP markers in Triplophysa (Hedinichthys) yarkandensis macroptera

Abstract

Triplophysa (Hedinichthys) yarkandensis macroptera is an endemic species in China, that is mainly distributed in Gansu Province. To date, research on this species has been very limited, focusing mainly on its taxonomy, without any available molecular markers. In the present study, we identified 55 SNP markers in T. (Hedinichthys) yarkandensis macroptera. The minor allele frequency ranged from 0.050 to 0.500, and the observed and expected heterozygosity ranged from 0.167 to 1.000 and 0.155 to 0.508, respectively. The polymorphic information content ranged from 0.141 to 0.375. Among these SNP markers, seventeen loci showed significant departures from Hardy-Weinberg equilibrium after Bonferroni correction. These novel SNP markers will be helpful for future studies on genetic management and population conservation in this species.
