Definition of the symbiovar viciae in the species Rhizobium azibense and biogeographic implications. Arch Microbiol 2023; 205:18.

Abstract
Vicia faba L. (faba bean) is a legume cultivated worldwide which commonly establishes effective symbiosis with the symbiovar viciae of species from the Rhizobium leguminosarum phylogenetic group. However, on the basis of the rrs, recA, and atpD gene phylogenies, in this work we identified a strain named EFBRI 42 nodulating V. faba as Rhizobium azibense. This is the first report on the nodulation of Vicia by R. azibense which commonly nodulates P. vulgaris and to date encompasses strains harboring the nodC genes typical of the symbiovars gallicum and phaseoli. However, the strain EFBRI 42 carries a nodC gene typical of the symbiovar viciae for which we report here by the first time this symbiovar in R. azibense. This finding showed the existence of symbiotic genes horizontal transfer events during the coevolution of R. azibense with P. vulgaris and V. faba in their respective distribution centers of Mesoamerica and the Middle East.

Abstract
Grain legumes play a significant role in smallholder farming systems in Africa because of their contribution to nutrition and income security and their role in fixing nitrogen. Biological Nitrogen Fixation (BNF) serves a critical role in improving soil fertility for legumes. Although much research has been conducted on rhizobia in nitrogen fixation and their contribution to soil fertility, much less is known about the distribution and diversity of the bacteria strains in different areas of the world and which of the strains achieve optimal benefits for the host plants under specific soil and environmental conditions. This paper reviews the distribution, characterization, and commercialization of elite rhizobia strains in Africa.

Ilahi H, Hsouna J, Ellouze W, Gritli T, Chihaoui SA, Barhoumi F, Najib Elfeddy M, Bachkouel S, Ouahmane L, Tambong JT, Mnasri B. Phylogenetic study of rhizobia nodulating pea (Pisum sativum) isolated from different geographic locations in Tunisia. Syst Appl Microbiol 2021; 44:126221. [PMID: 34119907 DOI: 10.1016/j.syapm.2021.126221] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 05/12/2021] [Accepted: 05/24/2021] [Indexed: 11/28/2022]
Abstract
Nodulated Pisum sativum plants showed the presence of native rhizobia in 16 out of 23 soil samples collected especially in northern and central Tunisia. A total of 130 bacterial strains were selected and three different ribotypes were revealed after PCR-RFLP analysis. Sequence analyses of rrs and four housekeeping genes (recA, atpD, dnaK and glnII) assigned 35 isolates to Rhizobium laguerreae, R. ruizarguesonis, Agrobacterium radiobacter, Ensifer meliloti and two putative genospecies. R. laguerreae was the most dominant species nodulating P. sativum with 63%. The isolates 21PS7 and 21PS15 were assigned to R. ruizarguesonis, and this is the first report of this species in Tunisia. Two putative new lineages were identified, since strains 25PS6, 10PS4 and 12PS15 clustered distinctly from known rhizobia species but within the R. leguminosarum complex (Rlc) with the most closely related species being R. indicum with 96.4% sequence identity. Similarly, strains 16PS2, 3PS9 and 3PS18 showed 97.4% and 97.6% similarity with R. sophorae and R. laguerreae, respectively. Based on 16S-23S intergenic spacer (IGS) fingerprinting, there was no clear association between the strains and their geographic locations. According to nodC and nodA phylogenies, strains of Rlc species and, interestingly, strain 8PS18 identified as E. meliloti, harbored the symbiotic genes of symbiovar viciae and clustered in two different clades showing heterogeneity within the symbiovar. All these strains nodulated and fixed nitrogen with pea plants. However, the strains belonging to A. radiobacter and the two remaining strains of E. meliloti were unable to nodulate P. sativum, suggesting that they were non-symbiotic strains. The results of this study further suggest that the Tunisian Rhizobium community is more diverse than previously reported.

Analysis of the Interaction between Pisum sativum L. and Rhizobium laguerreae Strains Nodulating This Legume in Northwest Spain. PLANTS 2020; 9:plants9121755.

Abstract
Pisum sativum L. (pea) is one of the most cultivated grain legumes in European countries due to the high protein content of its seeds. Nevertheless, the rhizobial microsymbionts of this legume have been scarcely studied in these countries. In this work, we analyzed the rhizobial strains nodulating the pea in a region from Northwestern Spain, where this legume is widely cultivated. The isolated strains were genetically diverse, and the phylogenetic analysis of core and symbiotic genes showed that these strains belong to different clusters related to R. laguerreae sv. viciae. Representative strains of these clusters were able to produce cellulose and cellulases, which are two key molecules in the legume infection process. They formed biofilms and produced acyl-homoserine lactones (AHLs), which are involved in the quorum sensing regulation process. They also exhibited several plant growth promotion mechanisms, including phosphate solubilization, siderophore, and indole acetic acid production and symbiotic atmospheric nitrogen fixation. All strains showed high symbiotic efficiency on pea plants, indicating that strains of R. laguerreae sv. viciae are promising candidates for the biofertilization of this legume worldwide.

Abstract
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 FB206T, 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 symbiosis-related 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.

Abstract
In this work, we analyzed the diversity of seventy-six bacteria isolated from Pea and faba bean nodules in two regions of Morocco. The molecular diversity was realized using the analysis of the sequences of 16S rRNA and six housekeeping genes (recA, glnII, atpD, dnaK, rpoB and gyrB) and two symbiotic genes (nodA and nodC). The phylogeny of the 16S rRNA gene sequences revealed that all strains belong to the genus Rhizobium, being related to the type strains of R. leguminosarum, R. laguerreae, R. indigoferae, R. anhuiense and R. acidisoli. The housekeeping genes phylogenies showed that some strains formed a subclade distinct from the rhizobial species that usually nodulate Vicia faba and Pisum sativum which are closely related to R. acidisoli FH23 with sequence similarity of 98.3%. Analysis of the PGPR activities of the different isolates showed that the strains related to R. laguerreae were able to solubilize phosphates and to produce siderophores and auxin phytohormone. However, R. acidisoli strain F40D2 was unable to solubilize phosphates although they produce siderophores and IAA. The phylogenetic analysis of the nodA and nodC sequences showed that all isolated strains were closely related with the strains of symbiovar viciae. The nodulation tests confirmed the ability to nodulate V. faba and P. sativum but not Cicer arietinum or Phaseolus vulgaris. Hence, in Morocco P. sativum is nodulated by R. laguerreae; whereas V. faba is nodulated by R. laguerreae and the symbiovar viciae of R. acidisoli which has been not previously described in this species.

Abstract
Nodulation and genetic diversity of native rhizobia nodulating Lathyrus cicera plants grown in 24 cultivated and marginal soils collected from northern and central Tunisia were studied. L. cicera plants were nodulated and showed the presence of native rhizobia in 21 soils. A total of 196 bacterial strains were selected and three different ribotypes were revealed after PCR-RFLP analysis. The sequence analysis of the rrs and two housekeeping genes (recA and thrC) from 36 representative isolates identified Rhizobium laguerreae as the dominant (53%) rhizobia nodulating L. cicera. To the best of our knowledge, this is the first time that this species has been reported among wild populations of the rhizobia-nodulating Lathyrus genus. Twenty-five percent of the isolates were identified as R. leguminosarum and isolates LS11.5, LS11.7 and LS8.8 clustered with Ensifer meliloti. Interestingly, five isolates (LS20.3, LS18.3, LS19.10, LS1.2 and LS21.20) were segregated from R. laguerreae and clustered as a separate clade. These isolates possibly belong to new species. According to nodC and nodA phylogeny, strains of R. laguerreae and R. leguminosarum harbored the symbiotic genes of symbiovar viciae and clustered in three different clades showing heterogeneity within the symbiovar. Strains of E. meliloti harbored symbiotic genes of Clade V and induced inefficient nodules.
