Genome Sequence of the Alphaproteobacterium Blastochloris sulfoviridis DSM 729, Which Requires Reduced Sulfur as a Growth Supplement and Contains Bacteriochlorophyll b

The genome sequence of Blastochloris sulfoviridis is 3.85 Mb with a GC content of 68%. Its nearest relative is B. tepida (average nucleotide identity [ANI], 91.5%), followed by B. viridis (ANI, 83%). According to ANI and whole-genome-based phylogenetic analysis, the nearest relatives of Blastochloris are Rhodoplanes and Rhodopseudomonas, confirming the recognition of distinct genera.

Complete Genome Sequence of the Bacteriochlorophyll b -Producing Photosynthetic Bacterium Blastochloris viridis

We report the complete genome sequence of the purple photosynthetic bacterium Blastochloris viridis belonging to α- Proteobacteria . This is the first completed genome sequence of a phototroph producing bacteriochlorophyll b . The genome information will be useful for further analysis of the photosynthetic energy conversion system and bacteriochlorophyll pigment biosynthesis.
