We present the genome sequence of Rhizobium sp. strain CCGE510, a nitrogen fixing bacterium taxonomically affiliated with the R. leguminosarum-R. etli group, isolated from wild Phaseolus albescens nodules grown in native pine forests in western Mexico. P. albescens is an endangered bean species phylogenetically related to P. vulgaris. In spite of the close host relatedness, Rhizobium sp. CCGE510 does not establish an efficient symbiosis with P. vulgaris. This is the first genome of a Rhizobium symbiont from a Phaseolus species other than P. vulgaris, and it will provide valuable new insights about symbiont-host specificity.
