Genome-wide survey reveals the Microsatellite characteristics and phylogenomic relationships of Dictyosoma burgeri (Zoarcales, Perciformes)

Dictyosoma burgeri widely distributed in the coastal water of China, Korea and Japan, while its phylogenomic and microsatellite DNA features have been poorly understood. Herein, we provide a new genome, D. burgeri, using the next-generation sequencing. About 632 Mb was assembled with GC contents of 42.09 %, leading to be prediction of 59,252 protein-coding gene models. Phylogenomic analyses show that D. burgeri is closely related with the Cebidichthys violaceus using 298 single copy genes of genomes, while D. burgeri is closely related with the genus Pholis based on 13 protein-coding genes of mitogenomes. A total of 689,658 simple sequences repeats (SSRs) were identified, and dinucleotide microsatellite motifs (accounting for 57.35 %) was the most abundant, followed with mononucleotide microsatellite motifs (accounting for 31.30 %). These results will help to obtain genetic information of D. burgeri and lay a theoretical basis as well as reference for genome-wide analyses.
