Next-generation sequencing yields the complete mitogenome of massive coral, Porites lutea (Cnidaria: Poritidae)

In this study, the complete mitogenome sequence of massive coral, Porites lutea (Cnidaria: Poritidae), has been sequenced by next-generation sequencing method. The overall base composition of Porites lutea mitogenome is 26.0% for A, 13.3% for C, 23.0% for G and 37.8% for T and have high AT content of 63.7%. The assembled mitogenome, consisting of 18 646 bp, has unique 13 protein-coding genes (PCGs), seven transfer RNAs and two ribosomal RNAs genes. The Porites lutea mitogenome has the common mitogenome gene organization and feature of scleractinian coral. Among 13 PCGs, ND5 and COX1 genes are interrupted by group I intron (11 130 and 971 bp, respectively). There are 13 genes embedded in ND5 group I intron (tRNA-Glu, ND1, CYTB, tRNA-Met, ND2, ND6, ATP6, ND4, 12S rRNA, COX3, COX2, ND4L and ND3), and two genes embedded in COX1 group I intron (tRNA-Ile and tRNA-Pro). The complete mitogenome provides essential and important DNA molecular data for further phylogenetic and evolutionary analysis for stony coral.
