Herein the members of Subcommittee on Taxonomy Rhizobia and Agrobacteria International Committee Systematics Prokaryotes review recent developments in rhizobial agrobacterial taxonomy propose updated minimal standards for description new species (and genera) these groups. The essential requirements (minimal standards) a are (1) genome sequence at least proposed type strain (2) evidence differentiation from other based comparisons. It is also recommended that (3) genetic variation within...
ABSTRACT We applied a multilocus phylogenetic approach to elucidate the origin of serradella and lupin Bradyrhizobium strains that persist in soils Western Australia South Africa. The selected belonged different randomly amplified polymorphic DNA (RAPD)-PCR clusters were distinct from RAPD inoculant strains. Phylogenetic analyses performed with nodulation genes ( nodA , nodZ nolL noeI ), housekeeping dnaK recA glnII atpD 16S-23S rRNA intergenic transcribed spacer sequences. Housekeeping gene...
A Rhizobium meliloti DNA region, determining nodulation functions common in different species, has been delimited by directed Tn5 mutagenesis and its nucleotide sequence determined. The data indicates three large open reading frames with the same polarity coding for proteins of 196, 217 402 (or 426) amino acid residues, respectively. We suggest existence nod genes on this which were designated as nodA, B C, Comparison R. B, C sequences those from leguminosarum, reported accompanying paper,...
ABSTRACT Bradyrhizobium strains isolated in Europe from Genisteae and serradella legumes form a distinct lineage, designated clade II, on nodulation gene trees. Clade II bradyrhizobia appear to prevail also the soils of Western Australia South Africa following probably accidental introduction with seeds their lupine hosts. Given this potential for dispersal, we investigated isolates originating range native New World lupines, based phylogenetic analyses ( nodA , nodZ noeI ) housekeeping atpD...
Given that several, mainly endemic South African Genisteae genera occupy basal positions in legume phylogenetic trees, this region of Africa is considered a primaeval centre diversification tribe. Despite the importance evolution, almost all studies have focused on rhizobia nodulating species their centres diversity either Mediterranean Basin or Americas. Therefore, study aimed to identify and characterize rhizobial strains associated with Argyrolobium native areas Grassland biome Great...
Abstract Aims Ultramafic/serpentine soils constitute a stressful environment with many plant growth constrains such as lack of macronutrients and high levels potentially toxic metals. We considered the adaptive strategy Lotus corniculatus L.-rhizobia symbiosis to Ni, Co Cr stress conditions. Methods L. nodulating rhizobia from ultramafic soil were isolated, identified tested for nitrogen fixation, metal tolerance promoting abilities. The structural immunocytochemical analyses root nodules...
Vachellia karroo (formerly Acacia karroo) is a wide-spread legume species indigenous to southern Africa. Little known regarding the identity or diversity of rhizobia that associate with this plant in its native range South The aims study were therefore: (i) gather collection associated V. from wide geographic locations and biomes; (ii) identify isolates infer their evolutionary relationships rhizobia; (iii) confirm nodulation abilities by using them inoculation assays induce nodules under...
Bradyrhizobium comprises a diverse group of bacteria with various lifestyles. Although best known for their nodule-based nitrogen-fixation in symbiosis legumes, select bradyrhizobia are also capable photosynthesis. This ability seems to be rare among rhizobia, and its origin evolution these remain subject substantial debate. Therefore, our aim here was investigate the distribution photosynthesis using comparative genomics representative genomes from closely related taxa families...
The fucosyltransferase NodZ is involved in the biosynthesis of nodulation factor nitrogen-fixing symbiotic bacteria. It catalyzes alpha1,6 transfer l-fucose from GDP-fucose to reducing residue synthesized Nod oligosaccharide. We present structure protein Bradyrhizobium expressed Escherichia coli and crystallized presence phosphate ions two crystal forms. enzyme arranged into domains nearly equal size. Although falls one broad class (GT-B) with other two-domain glycosyltransferases, topology...
Rhizobia, which enter into symbiosis with legumes, can also interact non-legumes and promote plant growth. In this paper, we explored the effects of nickel (Ni, 200 µM) on Arabidopsis thaliana (Col-0) inoculated growth-promoting (PGP) rhizobia nodulating ultramafic Anthyllis vulneraria. The isolated PGP strains tolerant to Ni were identified as Rhizobium sp. Bradyrhizobium isolates highly differed in their abilities resistance. Without Ni-stress, plants most grew better had higher...
A genetic element that allows the positive selection of different genomic rearrangements was used to analyze DNA amplification in Rhizobium leguminosarum biovar phaseoli. Discrete amplifiable regions (amplicons) were detected genome model strain CFN42, including chromosome and several large plasmids. Amplicons mobilized into Escherichia coli using a approach involves introduction an origin replication active E. conjugal transfer genome. The strategy can be valuable tool for studies on...
Prokaryotic organisms are exposed in the course of evolution to various impacts, resulting often drastic changes their genome size. Depending on circumstances, same lineage may diverge into species having substantially reduced genomes, or such whose genomes have undergone considerable enlargement. Genome reduction is a consequence obligate intracellular lifestyle rendering numerous genes expendable. Another effective population size and limited possibility gene acquirement via lateral...
