Tóm tắt

Two novel related Rhizobium species, Rhizobium grahamii sp. nov. and Rhizobium mesoamericanum sp. nov., were identified by a polyphasic approach using DNA–DNA hybridization, whole-genome sequencing and phylogenetic and phenotypic characterization including nodulation of Leucaena leucocephala and Phaseolus vulgaris (bean). As similar bacteria were found in the Los Tuxtlas rainforest in Mexico and in Central America, we suggest the existence of a Mesoamerican microbiological corridor. The type strain of Rhizobium grahamii sp. nov. is CCGE 502T ( = ATCC BAA-2124T  = CFN 242T  = Dal4T  = HAMBI 3152T) and that of Rhizobium mesoamericanum sp. nov. is CCGE 501T ( = ATCC BAA-2123T  = HAMBI 3151T  = CIP 110148T  = 1847T).
