摘要： Pareuchiloglanis sinensis (Siluriformes: Sisoridae) is an endemic and highland fish species which occurs only in some rivers of south-west China. In this study, the isolation and characterization of polymorphic microsatellite loci of this fish species by next-generation sequencing is described. A total of 9471 simple-sequence repeats (SSRs) were observed from RNA-seq data. One hundred and twenty primer pairs were chosen randomly and validated across 48 P. sinensis individuals collected from the Dadu river (a branch of the Yangtze river) of which 28 polymorphic microsatellite loci were detected. The number of alleles ranged from 2 to 14, with an average of seven alleles per locus. Twenty loci exhibited high polymorphism with the polymorphism information content (PIC) larger than 0.5. The mean observed and expected heterozygosity varied from 0.104 to 0.958 and 0.157 to 0.844, with an average of 0.583 and 0.613, respectively. The microsatellite markers characterized in the current study serve as a useful tool for the conversation genetic studies and population evaluation of P. sinensis.
