The Phylogenetic Tree Of The ‘Nod D’ Host-Specific Factor Is Incongruent With The Rhizobial Species Tree And Shows a Possible Hgt Event Between Highly Unrelated Rhizobial Bacteria

چکیده

Rhizobium is a symbiotic biological nitrogen-fixing (BNF) bacteria. and has high diversity in different geographical regions worldwide. The BNF associated with the legume trees tropical environments improves efficiency of nitrogen increases soil organic matter, fertility. consists Mesorhizobium, Sinorhizobium, Bradyrhizobium, species belonging to each genera infecting specific host. This host specificity dictated by several factors among which Nod D was secreted bacterium plays an important role. We investigated how gene sequences may have evolved confer specificity. constructed phylogenetic 16srRNA compared manually built tree. find that tree incongruent topology does not show any pattern correlative also uncover possible HGT between highly unrelated bacterial species. finding implications for development strains particular Agricultural purposes.
