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.

Keywords: Sargassum kjellmanianum; mitochondrial genome; phylogenetic analysis.
