The Given

The genetic diversity and phylogeny of rhizobia isolated from nodules of 9 wild-growing Lathyrus L. species (Fabaceae) growing in Republic Bashkortostan were studied. It is shown that for the given plants is characteristic that the big variety of heterogeneous strains of root nodule bacteria. Nevertheless, it is revealed that the majority of them in phylogenetics are closely related to Rhizobium leguminosarum. However, some plant species are found out also nodule bacteria which were considered earlier unusual for Lathyrus. So, L. vernus L. Bernh. and L. sylvestris L. are found out a root nodule bacteria close to R. tropici, L. palustris L. — Agrobacterium sp., and L. gmelinii Fritsch all isolated with us bacteria from root nodules by the sequence of genes of 16S рРНК have appeared are closely related to Phyllobacterium myrsinacearum.

And Chemical Properties

Using a sand pouch-plant infection method, populations of several species of root-nodule bacteria (rhizobia) were enumerated in eighty soils collected throughout Poland. <em>Rhizobium leguminosarum</em> bv. <em>viciae</em> (symbionts of pea, faba bean, vetch) and <em>R. leguminosarum</em> bv. <em>trifolii</em> (symbionts of clover) were detected in 77 and 76 soils, respectively. Most of these soils contained moderate and high numbers of these species of the rhizobia. Symbionts of beans, <em>R. leguminosarum</em> bv.<em> phaseoli</em>, were assessed in 76 soils; of this number 15 soils had no detectable populations of bean rhizobia and in 40 soils high or moderate numbers of these bacteria were found. <em>Bradyrhizobium</em> sp. (<em>Lupinus</em>), root-nodule bacteria of lupine and serradella, were absent in 19 soils, out of 80 tested, and 34 soils were colonised by high or moderate populations of bradyrhizobia. <em>Sinorhizobium meliloti</em>, rhizobia nodulating alfalfa, were sparse in the examined soils; with 56 soil containing no detectable numbers of <em>S. meliloti</em> and only 6 soils harbouring high or moderate populations of this species. The estimated numbers of the rhizobia in the studied soils were also related to some physical and chemical properties of these soils.

Phenotypic Clustering

In this study, bacteria (8 species and 5 genera) belonging to the classes Betaproteobacteria, Gammaproteobacteria, and Sphingobacteria were isolated from root nodules of the multipurpose legume Clitoria ternatea L. and identified on the basis of partial 16S rRNA sequencing. The root nodule bacteria were subjected to phenotypic clustering and diversity studies using biochemical kits, including Hi-Media Carbokit™, Enterobacteriaceae™ identification kit, ERIC–PCR, and 16S ARDRA. All the strains showed growth on Ashby’s N-free media over 7 generations, indicative of presumptive nitrogen fixation and further confirmed by amplification of the nifH gene. None of the strains showed the capability to renodulate the host plant, neither alone nor in combination with standard rhizobial strains, which was further confirmed by the absence of nodC bands in PCR assay. The results clearly indicate the common existence of nonrhizobial microflora inside the root nodules of legumes, which were thought to be colonized only by rhizobia and were responsible for N2fixation in leguminous crops. However, with the recent discovery of nodule endophytes from a variety of legumes, as also observed here, it can be assumed that symbiotic rhizobia are not all alone and that these invasive endophytes belonging to various bacterial genera are more than just opportunistic colonizers of specialized nodule niche.
