Other claims from this paper (8)
- Observation 16S rDNA sequencing clustered the rhizobial isolates into four distinct groups.
- Observation Medicago sativa nodules contained only S. meliloti and R. leguminosarum.
- Observation Medicago falcata nodules hosted S. meliloti and Mesorhizobium spp.
- Observation Medicago lupulina was the only species whose nodules hosted all four rhizobial groups, including S. medicae.
- Observation This study is the first report of Mesorhizobium spp. associated with M. falcata nodules.
- Observation R. leguminosarum and two Mesorhizobium genospecies were identified as novel symbionts of Medicago spp.
- Association Differences in 16S rDNA sequence type composition were associated with Medicago species identity rather than geographic region.
- Observation Phylogenies of the chromosomal genes atpD, glnII and recA and of nifH were congruent.
