Identification of sex determination locus in sea cucumber Apostichopus japonicus using genome-wide association study.

ABSTRACT:

Background

Sex determination mechanisms are complicated and diverse across taxonomic categories. Sea cucumber Apostichopus japonicus is a benthic echinoderm, which is the closest group of invertebrates to chordate, and important economic and ecologically aquaculture species in China. A. japonicus is dioecious, and no phenotypic differences between males and females can be detected before sexual maturation. Identification of sex determination locus will broaden knowledge about sex-determination mechanism in echinoderms, which allows for the identification of sex-linked markers and increases the efficiency of sea cucumber breeding industry.

Results

Here, we integrated assembly of a novel chromosome-level genome and resequencing of female and male populations to investigate the
