Rhizobiales are Alphaproteobacteria with many distinctive model organisms, including the animal pathogens Brucella and Bartonella, the plant pathogen and natural genetic engineer Agrobacterium, the plant symbiont Sinorhizobium, and the metabolically diverse Rhodopseudomonas.

2015年2月9日 · Rhizobiales are well-studied associates of plants; they commonly exert beneficial functions for their hosts by providing various nutrients, phytohormons as well as precursors for essential plant metabolites (Ivanova et al., 2000; Delmotte et al., 2009; Verginer et al., 2010).

2018年5月22日 · Rhizobiales comprises not only nitrogen-fixing bacteria, such as Rhizobium spp. and Bradyrhizobium spp., but also members of the genus Methylobacterium, which is known to be endosymbiotic and ...

Rhizobia are a paraphyletic group of soil-borne bacteria that induce nodule organogenesis in legume roots and fix atmospheric nitrogen for plant growth. In non-leguminous plants, species from the Rhizobiales order define a core lineage of the plant ...

2021年2月16日 · The bacterial order of Rhizobiales (Alpha class of the Proteobacteria phylum) is a taxonomically wide group that currently harbors 15 families, within which, few species possess the capability of engaging nitrogen-fixing symbiotic relationships with legume plants. The order is overtly polyphyletic.

Rhizobia are Gram-negative, free-living soil bacteria, which can induce formation of root (or sometimes stem) nodules on legume plants. Inside these structures, they are able to fix atmospheric nitrogen and convert it into plant available compounds [1–3].

2023年1月10日 · Rhizobiales members are overrepresented in the core root microbiome of terrestrial plants, and here we report a genome-wide transposon-sequencing of rhizoplane fitness genes of beneficial...

2018年1月30日 · Rhizobia are some of the best-studied plant microbiota. These oligotrophic Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts. Rhizobia must exist in soil and...

2014年11月11日 · Rhizobiaceae is a family of Rhizobiales order into Alphaproteobacteria class that presents genera associated with soil and planta hosts. Rhizobium is the type genus and encompasses the largest number of species into the family.

Rhizobium and Bradyrhizobium (class of the Alphaproteobac- teria, order of the Rhizobiales) are Gram-negative nitrogen-fixing bacteria that occur either as free-living soil bacteria or in interaction with the roots of leguminous plants. Cohabitation leads to the development of root nodules.
