Abstract
The genetic diversity of bacterial communities associated with mycorrhizal and nonmycorrhizal roots of Medicago truncatula was characterized by two approaches. Firstly, phylogenetic analysis was performed on 164 partial 16S rRNA gene-intergenic spacer (IGS) sequences from operational taxonomic units previously shown to be preferentially associated with mycorrhizal roots. These sequences were distributed into three branches corresponding to Comamonadaceae, Oxalobacteraceae and Rubrivivax subgroups. Most sequences were obtained from mycorrhizal roots, indicating the preferential association of the corresponding families with mycorrhizal roots. A second phylogenetic analysis was performed on the partial 16S rRNA gene-IGS sequences of 173 isolates among a large collection of isolates, from mycorrhizal and nonmycorrhizal roots, belonging to Comamonadaceae and Oxalobacteraceae on the basis of their positive hybridization with a partial 16S rRNA gene-IGS probe obtained in this study. Sequence analysis confirmed the affiliation of 166 isolates to Comamonadaceae and seven to Oxalobacteraceae. Oxalobacteraceae isolates were more abundant in mycorrhizal (five) than in nonmycorrhizal (two) roots, whereas Comamonadaceae isolates were more abundant in nonmycorrhizal (109) than mycorrhizal roots (57). Further analysis of Comamonadaceae isolates by BOX-PCR showed that the genetic structure of culturable populations belonging to this family differed significantly in mycorrhizal and nonmycorrhizal roots, as indicated by distributions in different BOX types, differences being significantly explained by BOX types only including isolates from mycorrhizal roots. These data are discussed in an ecological context.
