AFLP markers suggest low population genetic differentiation of the black rockfish Sebastes schlegelii

Publication date: April 2015 Source:Biochemical Systematics and Ecology, Volume 59 Author(s): Hui Zhang , Xiumei Zhang , Zhiqiang Han , Tianxiang Gao AFLP markers were used to investigate the population genetic differentiation among populations of Sebastes schlegelii from China and Japan. A total of 405 bands were amplified for 180 individuals from 9 populations by 3 pairs of selective primers. S. schlegelii exhibited high Nei's gene diversity with an average value of 0.29 for all populations. No significant genealogical branches or clusters corresponding to sampling localities were detected by UPGMA tree. The results of AMOVA analysis and pairwise F ST values showed no genetic divergence among different geographic populations. The result of STRUCTURE demonstrated all populations of S. schlegelii examined in the study shared one single gene pool.
