“…It was noteworthy that R. anhuiense CCBAU 23252 T , R. hidalgonense FH14 T , R. laguerreae FB206 T , Rlv USDA 2370 T , R. ruizarguesonis UMP1133 T and R. sophorae CCBAU 03386 T displayed identical rrs sequences, which was consistent with previous reports [22,24,55,75]. The isolate VFEP82 formed a distinct cluster with Rhizobium cauense CCBAU 101002 T , which was originally isolated from the herbaceous legume Kummerowia stipulacea in China [35], and they showed a 99.77% rrs similarity. The analysis of the rrs gene could not assign the studied strains at the species level, which was in agreement with the general view that the rrs gene is an insufficient phylogenetic marker for species delineation [16].…”

The genetic diversity and phylogeny of fast-growing rhizobia isolated from root nodules of Vicia faba grown in different geographical regions of Greece were assessed. Although Rhizobium leguminosarum sv. viciae is the most common symbiont of Vicia spp. in European soils, there is no available information on native rhizobia nodulating faba bean in Greece. Seventy bacterial strains were isolated and grouped into sixteen distinct profiles based on BOX-PCR fingerprinting. The phylogenetic affiliation was further defined by sequence analysis of the rrs and multilocus sequence analysis (MLSA) of three housekeeping genes (recA, atpD and gyrB). Fifty-eight isolates were affiliated with recently described genospecies gsF-2, represented by R. laguerreae FB206 T , whereas six isolates were closely related to gsB and two isolates might belong to gsA. Two isolates assigned to R. hidalgonense and another two non-nodulating strains could not be assigned to any validly defined species and possibly belong to a new rhizobial lineage. Interestingly, R. laguerreae strains were commonly found at all sampling sites, suggesting that they could be the main symbionts of faba beans in Greek soils. According to the phylogenies of two symbiosisrelated genes (nodC and nifH), all nodulating isolates belonged to symbiovar (sv.) viciae harboring four distinct nodC gene haplotypes and they were grouped into two clades together with strains assigned to R. laguerreae and genospecies of R. leguminosarum isolated from other countries and continents. This is the first report that R. hidalgonense strains belong to sv. viciae. No correlation was observed between the nodC haplotypes, geographic origin and chromosomal background of the isolates in the study.

Root-Nodule Bacteria of Legumes Growing in Semi-Arid African Soils and Other Areas of the World

In Africa, arid and semi-arid soils are characterized by a diverse occurrence of plants including nodulated legumes which are adapted to the prevailing and often harsh environmental conditions. Such soils also harbour a large diversity of indigenous rhizobial symbionts (comparable to legume diversity) and other bacterial endophytes that have a potential to be developed into elite strains to be used as inoculum. However, very few studies have investigated the diversity of root-nodule bacteria on African soils, the main reason being that funds for research are often lacking. Discoveries of new rhizobial species are to be expected from different soil ecologies that are likely to be inhabited by various types of microorganisms. It is concluded that the semi-arid and arid African soils have rhizobia that is possibly as equally diverse as their host legumes. Research in these areas is likely to find novel species with a great potential for use in agricultural systems.
