Complete sequence of mitochondrial DNA of Gracilaria edulis (Rhodophyta)

Abstract

Herein, the complete Gracilaria edulis mitogenome was determined and analysed. The complete G. edulis mitogenome length was 25,708 bp. The mitogenome contains 50 genes, including 24 protein-coding, two rRNA, and 23 tRNA genes and one unidentified open reading frame (ORF). Of the 24 protein-coding genes, 23 (95.83%) ended with the TAA stop codon, and one (4.17%) with TAG (rpl20). All protein-coding genes in G. edulis were concluded to use the start codon ATG. Mitogenome phylogenetic analysis revealed that G. edulis clustered together with G. changii and G. salicornia. The complete mitogenome sequence provided herein would help understand Gracilaria evolution.
