Abstract

In this study, the complete mitogenome sequence of Galaxy Coral, Galaxea fascicularis (Cnidaria: Oculinidae), has been sequenced by next-generation sequencing method. The overall base composition of Galaxea fascicularis mitogenome is 24.9% for A, 14.0% for C, 24.3% for G and 36.8% for T and has low GC content of 38.3%. The assembled mitogenome, consisting of 18 751 bp, has unique 13 protein-coding genes (PCGs), three transfer RNAs and two ribosomal RNAs genes. The G. fascicularis mitogenome has the common mitogenome gene organization and feature of scleractinian coral. Among 13 PCGs, ND5 gene is interrupted by group I intron (12 022 bp). There are 12 genes embedded in ND5 group I intron (tRNA-Leu, ND1, CYTB, ND2, ND6, ATP6, ND4, 12S rRNA, COX3, COX2, ND4L and ND3). The complete mitogenome provides essential and important DNA molecular data for further phylogenetic and evolutionary analysis for stony coral.
