  1. The comparison was done with Klebsiella pneumoniae as reference and other rhizobial strains with fully sequenced genomes. Kp, Klebsiella pneumoniae; BTAi1, Bradyrhizobium sp. BTAi1; CFN42, R. etli CFN42; CIAT899, R. tropici CIAT 899; CCGE501, R. mesoamericanum CCGE501; STM3625, R. mesoamericanum STM3625; CCGE502, R. grahamii CCGE502; Bd, Bradyrhizobium diazoefficiens USDA110; Ml, Mesorhizobium loti MAFF303099; Em, Ensifer meliloti 1021 and Rl 3841, Rhizobium leguminosarum sv. viciae 3841. In rhizobia, FixU functionally replaces NifT. Modified and updated from [56].
