Abstract

We report here the complete chloroplast genome sequence of the strain BAC9706 of green microalga Chlorella vulgaris isolated from Lake Baikal. The chloroplast genome is a circular DNA molecule of 161,721 bp and contains 78 protein-coding genes, 33 tRNA genes, and 3 rRNA genes. Comparative analysis revealed a high level of conservation of gene content and gene order among other C. vulgaris strains with minor differences mainly associated with introns and non-coding regions. Phylogenetic analysis based on concatenated chloroplast protein-coding genes showed that strain BAC9706 clusters within the C. vulgaris clade with high bootstrap support. These results indicate that strain BAC9706 represents a Baikal ecotype of C. vulgaris rather than a new species.
