Phylogenetic tree of representatives nodD genes of some relevant rizobia. The branchs length represents the evolutionary lineages changing over time. The length of the brach represents the amount of changes and it is proportional to the number of nucleotide substitutions per site. The bar at the bottom of the figure provides a scale for the evolution. The numbers next to each node represent a measure of support for the node (between 0 and 1). A high value means that there is strong evidence that the sequences to the right of the node cluster together to the exclusion of any other. Phylogenetic tree was built as described in the Methods section. In this phylogenetic tree, nodD1 to nodD5 CIAT 899 correspond to Rhizobium tropici CIAT 899 nodD genes; nodD1 to nodD5 PRF 81 correspond to Rhizobium freirei PRF 81 nodD genes; nodD1 to nodD3 IE 4803 correspond to Rhizobium etli sv. phaseoli IE 4803 nodD genes; nodD1 to nodD3 1021 correspond to Sinorhizobium meliloti 1021 nodD genes; and nodD1 and nodD2 USDA 76 correspond to Bradyrhizobium elkanii USDA 76 nodD genes.
