(a) Average number of photoreceptors per cell in MTB, phototrophic bacteria and nonphototrophic nonmagnetotactic bacteria within the family Rhodospirillaceae. Photoreceptors were sorted by the following types: cryptochrome, PYP, PHP, LOV and BLUF domain-containing proteins. (Note: the number represents the total number of a certain type of photoreceptor divided by the bacterial genome number). (b) Photoreceptors predicted from the completely sequenced MTB strains XM-1, MSR-1, AMB-1, QH-2, phototrophic bacteria strains S1 and SW and nonphototrophic nonmagnetotactic bacteria Az39 and B510. (c) Phylogenetic trees based on the PHY domain-containing photosensor protein sequences from the genomes of the Rhodospirillaceae family
