Bio-priming of soybean with Bradyrhizobium japonicum and Bacillus megaterium
<p>The data represent the impact of single and co-inoculation with<em> Bradyrhizobium japonicum</em> and <em>Bacillus megaterium</em> on seed germination and initial seedling growth of two soybean cultivars, under optimal and stressful conditions. Three laboratory tests,<em> i.e</em>., germination test, cold test, and accelerated aging test, were performed in order to evaluate seed quality and viability in relation to the applied bacterial treatments.</p> <p>The data are related to the publication of Miljakovic et al. (2022); doi: 10.3390/plants11151927</p>

Fig. 3 in Bradyrhizobium altum sp. nov., Bradyrhizobium oropedii sp. nov. and Bradyrhizobium acaciae sp. nov. from South Africa show locally restricted and pantropical nodA phylogeographic patterns
Fig. 3. Aheatmap illustrating the Average Nucleotide Identity (ANIb) similarity between Bradyrhizobium type strains within the B. elkanii supergroup. ANIb pairwise values were calculated using BLAST in JSpecies. Strains of the species investigated here are indicated in their respective colours. The black boxes around the strains highlight the strains investigated in this study and their closest relatives.
Fig. 2 in Bradyrhizobium altum sp. nov., Bradyrhizobium oropedii sp. nov. and Bradyrhizobium acaciae sp. nov. from South Africa show locally restricted and pantropical nodA phylogeographic patterns
Fig. 2. Cladogram inferred from the concatenated (atpD, dnaK, glnII, gyrB and rpoB) maximum-likelihood phylogeny. Only type strains from the B. elkanii supergroup were included in the analysis. Bradyrhizobium japonicum USDA6T was used as an outgroup. Bootstrap support values were inferred from 1000 replicates and only values greater than 60% are indicated in bold at the nodes, while branch lengths (i.e. indicative of the nucleotide substitutions per site) are shown below the branches. Strains of the species investigated here are indicated in their respective colours. For each taxon, the legume tribe, host and geographic location from where it was isolated is also listed, including their nodA clade affiliation. Bradyrhizobium species with no available nodA sequence is indicated as "na" under nodA Clade. The P and Cin brackets behind the Tribe indicate subfamily Papilionoideae or Caesalpinioideae, while Mindicates the Mimosoid Clade within the Caesalpinioideae. The closest town names from which the South African strains were isolated were also included under geographic location.
Fig. 1 in Bradyrhizobium altum sp. nov., Bradyrhizobium oropedii sp. nov. and Bradyrhizobium acaciae sp. nov. from South Africa show locally restricted and pantropical nodA phylogeographic patterns
Fig. 1. Individual maximum-likelihood phylogenies of atpD, dnaK, glnII, gyrB and rpoB housekeeping genes. These phylogenies only include Bradyrhizobium type strains from the B. elkanii supergroup, although the atpD phylogeny did not include B. ripae WT4T, B. erythrophlei CCBAU 53325T, and B. ferriligni CCBAU 51502T due to the lack of sequence data. In each phylogeny B. japonicum USDA6T was used as the outgroup. Strains of the species investigated in this study are indicated in colour. Bootstrap values were inferred from 1000 replicates and only those greater than 60% are shown on the nodes. The scalebars indicates nucleotide substitutions per site.
Data from: Metapopulation dominance and genomic-island acquisition of Bradyrhizobium with superior catabolic capabilities
Root nodule forming rhizobia exhibit a bipartite lifestyle, replicating in soil and also within plant cells where they fix nitrogen for legume hosts. Host control models posit that legume hosts act as a predominant selective force on rhizobia, but few studies have examined rhizobial fitness in natural populations. Here, we genotyped and phenotyped Bradyrhizobium isolates across >800km of the native Acmispon strigosus host range. We sequenced chromosomal genes expressed under free-living conditions and accessory symbiosis loci expressed in planta and encoded on an integrated 'symbiosis island'. We uncovered a massive clonal expansion restricted to the Bradyrhizobium chromosome, with a single chromosomal haplotype dominating populations, ranging >700km, and acquiring 42 divergent symbiosis island haplotypes, none of which were spatially widespread. For focal genotypes we quantified utilization of 190 sole-carbon sources relevant to soil fitness. Chromosomal haplotypes that were both widespread and dominant exhibited superior growth on diverse carbon sources, whereas these patterns were not mirrored among symbiosis island haplotypes. Abundance, spatial range, and catabolic superiority of chromosomal, but not symbiosis genotypes suggests that fitness in the soil environment, rather than symbiosis with hosts, might be the key driver of Bradyrhizobium dominance.
