Isolation and characterisation of 17 microsatellite DNA loci from RAD reduced-representation genomes for Asian warty newts, genus Paramesotriton (Caudata: Salamandridae)

Abstract

Asian warty newts, genus Paramesotriton, are endemic to southern China and northern Vietnam. Despite the achievements in biodiversity, molecular systematics and biogeography of species in this genus, population genetic diversity studies are lacking due to the lack of economical and available genetic markers. In this study, we developed 17 highly polymorphic microsatellite loci from RAD simplified genomic data for the Asian warty newts, genus Paramesotriton and successfully completed cross-species amplification tests on 20 samples of four species of Paramesotriton. These microsatellite markers can be used as important tools to study population genetic structure, levels of gene flow, population differentiation, mating systems and landscape genetics within the genus Paramesotriton and, thus, to make scientific conservation decisions and actions for the conservation of these rare and endangered amphibians.
