Genetic differentiation in Palaemon septemtrionalis between populations of two rivers examined by newly developed short tandem repeat markers

抄録

We developed short tandem repeat markers for Palaemon septemtrionalis and tested their utility for analysing population genetics. Six markers were selected for their genotyping ability and suitability for population genetic analyses, and the genetic differences between two populations from different rivers were evaluated using these markers. The pairwise fixation index value between the two populations was 0.01756 (P=0.036), weak but statistically significant, suggesting a low level of genetic differentiation between the two populations. Although the results were not fully conclusive, we are confident these markers can be utilised for investigating the genetic population structure of P. septemtrionalis.
