These isolates had cultural characteristics on YMA quite similar to Azorhizobium caulinodans (alkalinization, scant extracellular polysaccharide production, fast or intermediate growth rate). They exhibited a high similarity of phenotypic and genotypic characteristics among themselves and to a lesser extent with A. caulinodans. DNA:DNA hybridization and 16SrRNA sequences support their inclusion in the genus Azorhizobium, but not in the species A. caulinodans. The name A. doebereinerae is proposed, with isolate UFLA1-100 ( ¼ BR5401, ¼ LMG9993 ¼ SEMIA 6401) as the type strain. -

Since then the taxonomy of bacteria has been revolutionized several times. At present, 30 phyla belong to the domain “Bacteria”, which includes over 9600 species. Unlike many eukaryotes, bacteria lack complex morphological characters and practically phylogenetically informative fossils. It is partly due to these reasons that bacterial taxonomy is complicated. -

Bradyrhizobium Ivorense Sp. Nov. As a Potential Local Bioinoculant for Cajanus Cajan Cultures in Côte D’Ivoire
TAXONOMIC DESCRIPTION Fossou et al., Int. J. Syst. Evol. Microbiol. 2020;70:1421–1430 DOI 10.1099/ijsem.0.003931 Bradyrhizobium ivorense sp. nov. as a potential local bioinoculant for Cajanus cajan cultures in Côte d’Ivoire Romain K. Fossou1,2, Joël F. Pothier3, Adolphe Zézé2 and Xavier Perret1,* Abstract For many smallholder farmers of Sub- Saharan Africa, pigeonpea (Cajanus cajan) is an important crop to make ends meet. To ascertain the taxonomic status of pigeonpea isolates of Côte d’Ivoire previously identified as bradyrhizobia, a polyphasic approach was applied to strains CI-1B T, CI- 14A, CI- 19D and CI- 41S. Phylogeny of 16S ribosomal RNA (rRNA) genes placed these nodule isolates in a separate lineage from current species of the B. elkanii super clade. In phylogenetic analyses of single and concatenated partial dnaK, glnII, gyrB, recA and rpoB sequences, the C. cajan isolates again formed a separate lineage, with strain CI- 1BT sharing the highest sequence similarity (95.2 %) with B. tropiciagri SEMIA 6148T. Comparative genomic analyses corroborated the novel species status, with 86 % ANIb and 89 % ANIm as the highest average nucleotide identity (ANI) values with B. elkanii USDA 76T. Although CI- 1BT, CI- 14A, CI- 19D and CI- 41S shared similar phenotypic and metabolic properties, growth of CI- 41S was slower in/on various media. Symbiotic efficacy varied significantly between isolates, with CI- 1BT and CI- 41S scoring on the C. cajan ‘Light- Brown’ landrace as the most and least proficient bacteria, respectively. Also proficient on Vigna radiata (mung bean), Vigna unguiculata (cowpea, niébé) and additional C. -

Functional Genomics Approaches to Studying Symbioses Between Legumes and Nitrogen-Fixing Rhizobia
Review Functional Genomics Approaches to Studying Symbioses between Legumes and Nitrogen-Fixing Rhizobia Martina Lardi and Gabriella Pessi * ID Department of Plant and Microbial Biology, University of Zurich, CH-8057 Zurich, Switzerland; [email protected] * Correspondence: [email protected]; Tel.: +41-44-635-2904 Received: 9 April 2018; Accepted: 16 May 2018; Published: 18 May 2018 Abstract: Biological nitrogen fixation gives legumes a pronounced growth advantage in nitrogen- deprived soils and is of considerable ecological and economic interest. In exchange for reduced atmospheric nitrogen, typically given to the plant in the form of amides or ureides, the legume provides nitrogen-fixing rhizobia with nutrients and highly specialised root structures called nodules. To elucidate the molecular basis underlying physiological adaptations on a genome-wide scale, functional genomics approaches, such as transcriptomics, proteomics, and metabolomics, have been used. This review presents an overview of the different functional genomics approaches that have been performed on rhizobial symbiosis, with a focus on studies investigating the molecular mechanisms used by the bacterial partner to interact with the legume. While rhizobia belonging to the alpha-proteobacterial group (alpha-rhizobia) have been well studied, few studies to date have investigated this process in beta-proteobacteria (beta-rhizobia). Keywords: alpha-rhizobia; beta-rhizobia; symbiosis; transcriptomics; proteomics; metabolomics; flavonoids; root exudates; root nodule 1. Introduction Nitrogen fixation in agricultural systems is of enormous agricultural importance, as it increases in situ the fixed nitrogen content of soil and can replace expensive and harmful chemical fertilizers [1]. For over a hundred years, all of the described symbiotic relationships between legumes and nitrogen-fixing rhizobia were confined to the alpha-proteobacteria (alpha-rhizobia) group, which includes Bradyrhizobium, Mesorhizobium, Methylobacterium, Rhizobium, and Sinorhizobium [2]. -
Stem-Nodulating Nitrogen-Fixing Bacterium Isolated from Sesbania Rostrata

Representative organisms from the different clusters were investigated further, together with possibly related organisms, by performing comparative gel electrophoresis of whole-cell proteins and by performing deoxyri- bonucleic acid (DNA)-DNA and DNA-ribosomal ribonucleic acid (rRNA) hybridizations. 3H-labeledrRNA was prepared from Sesbunia stem- and root-nodulating bacterial strain ORS 571T (T = type strain); [14C]rRNA from Bradyrhizobium japonicum NZP 5549T was also used. The following conclusions were drawn: (i) the Sesbania root-nodulating bacterial strains are genuine rhizobia; (ii) the Sesbania stem- and root-nodulating strains are quite different from Rhizobium and Bradyrhizobium, and thus they constitute a separate rRNA subbranch on the Rhodopseudomonas palusfris rRNA branch in rRNA superfamily IV; and (iii) the closest relative of these organisms is Xanthobacfer, but they are phenotypically and genotypically sufficiently different from the latter genus to deserve a separate generic rank. -

PhoD and PhoX alkaline phosphatases and AcpA acid phosphatase are produced by microorganisms in response to phosphorus limitation in the environment. In this thesis, the current knowledge of the prevalence of phoD and phoX in the environment and of their taxonomic distribution was assessed, and new molecular tools were developed to target the phoD and phoX alkaline phosphatase genes in soil microorganisms. -
