Complete mitochondrial genome of a red calcified alga Calliarthron tuberculosum (Corallinales)

Abstract

454 GS FLX Titanium sequencing data were used to obtain the complete mitochondrial genome of Calliarthron tuberculosum (26,469 bp). The mitogenome contains 44 genes, including 2 ribosomal RNA, 19 transfer RNA, 5 ribosomal proteins, 1 ymf, 2 open reading frames (ORFs) and 16 genes involved in cellular respiration. The secY and rps12 are overlapped by 69 bp. rps3 and rpl16 also have a 45 bp overlapped region. Except for open reading frames near stem-loop region, the results show Calliarthron tuberculosum mtDNA has a high similarity with other Florideophyceae algae mitogenomes in gene synteny, structure and gene content. Phylogeny analysis indicates a close genetic relationship of Calliarthron tuberculosum with Sporolithon durum.
