Abstract

We sequenced and analysed the complete mitogenome of Gracilaria tenuistipitata. The complete G. tenuistipitata mitogenome is 25,819 bp long, containing 50 genes, including 24 protein-coding genes, one intron, two rRNA genes, 23 tRNA genes, and one unidentified open reading frame. Twenty-three of the 24 (95.83%) protein-coding genes ended with the TAA stop codon, and one (4.17%) with TAG (rps3 gene). All protein-coding genes in G. tenuistipitata were found to contain the start codon ATG. Phylogenetic analysis revealed that G. tenuistipitata clustered with G. chilensis. The complete mitochondrial genome sequence provided here should be useful for elucidation of Gracilaria evolution.

Keywords: Gracilaria tenuistipitata; mitogenome; phylogenetic tree.
