Phylogenetic tree based on the CrtB sequences and constructed by using the neighbor-joining method (22). Bootstrap values (5), expressed as percentages of 1,000 replications, are given at the branching points. P, Proteobacteria; F, Flavobacteria; a, bicyclic carotenoid; b, acyclic carotenoid; c, monocyclic carotenoid. GenBank accession numbers are as follows: AF218415, Bradyrhizobium sp. strain ORS278; D58420, A. aurantiacum; Y15112, Paracoccus marcusii; U62808, Flavobacterium sp.; M87280, E. herbicola EHO10; M90698, E. herbicola 557; D90087, E. uredovora; AF195122, R. sphaeroides; X52291, Rhodobacter capsulatus; U87626, Rubrivivax gelatinosus; Z211955, Myxococcus xanthus.
