Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Jul;27(4):2619-20. doi: 10.3109/19401736.2015.1041122. Epub 2015 Jun 29.

Abstract

Complete mitochondrial genome of Botryococcus braunii strain Showa was assembled and annotated. It contains 31 protein-coding genes, 23 tRNA genes and 3 rRNA (23S, 16S, 5S rRNA) genes. The 31 protein-coding genes include 5 atp genes, 3 cox genes, 9 nad genes, 12 ribosomal protein genes, cob and tatC genes. The presence of extra non-coding regions makes it currently the largest mitochondrial genome in Trebouxiophyceae. Phylogenetic analysis showed Botryococcus braunii strain Showa clustered into Trebouxiophyceae clade and had close genetic relationship with algae Coccomyxa sp. C-169.

Keywords: Botryococcus braunii; Trebouxiophyceae; mitochondrial genome.
