Twenty-four novel microsatellites for the endangered Chinese sturgeon ( Acipenser sinensis Gray, 1835).

The Chinese sturgeon ( Acipenser sinensis) is an endemic and critically endangered species in China. In this study, a total of 24 polymorphic microsatellite loci were isolated and characterized using Illumina sequencing for A. sinensis. The number of alleles (Na) per locus ranged from 2 to 6 (mean 4.04), mean expected heterozygosities (He), Shannon-Wiener Diversity Indices (SW) and evenness (E) per locus ranged from 0.235 to 0.786 (mean 0.62), from 0.396 to 1.608 (mean 1.13), and from 0.060 to 0.213 (mean 0.13), respectively. Exact tests revealed that nine loci showed significant (P < 0.01) deviation from Hardy-Weinberg equilibrium (HWE). Cross amplification was tested in congeneric species A. schrenskii, A. baerii, A. dabryanus and Huso dauricus. The new microsatellite markers described herein will be useful for further studies on genetic variation, parentage analysis, and conservation management. [ABSTRACT FROM AUTHOR]
