The complete mitochondrial genome of Sargassum kjellmanianum (Sargassaceae) and phylogenetic analysis of Sargassum kjellmanianum (Sargassaceae)

Abstract

Sargassum kjellmanianum plays an important role in marine ecosystem and biological resource utilization. Here, we analyzed the characteristics and evolution of mitochondrial genome of S. kjellmanianum by paired-end sequencing. The complete mitogenome comprises a circular DNA molecule measuring 34,723 bp in length with 35 coding genes. The circular genome consisted of seven protein-coding genes, 25 tRNA genes, and three rRNA genes, with a total length of 26,553 bp. The overall A + T content was 63.43%, higher than the G + C content (36.57%). Phylogenetic analysis confirmed S. kjellmanianum was closely clustered with S. muticum.
