Complete mitochondrial genome of agar-producing red alga Gracilariopsis chorda (Gracilariales)

We sequenced the complete mitochondrial genome of Gracilariopsis chorda (Gracilariales, Rhodophyta), which is an agar-producing economic red algal species distributed in the northwest Pacific. The mitogenome is 26,534 bp in length with 27.7% GC content that consists of 52 genes including 26 protein-coding, 2 rRNA and 24 tRNA genes. We compared G. chorda mitogenome with that of recently published G. lemaneiformis. Nucleotide sequence similarity between these two mitogenomes was 99.82%, however, there was significant difference in length caused by trnR trnS and trnY genes missing in G. lemaneiformis.
