Congo red absorption and cellulose synthesis by Rhizobiaceae

Antonie Van Leeuwenhoek, 1986
Congo red uptake by Rhizobium colonies from yeast extract-mannitol-mineral salts-Congo red-agar plates was related with the cellulose content in the cell capsule of the bacteria.

Lipopolysaccharide structures from Agrobacterium and Rhizobiaceae species

Carbohydrate Research, 2008
This review reports and discusses the structural and the biological data available for the lipopolysaccharides from the Gram-negative bacterium Agrobacterium together with those of other related Rhizobiaceae species.

Soil Biology of the Rhizobiaceae

1998
The family Rhizobiaceae is comprised of six genera of plant-associating bacteria, Rhizobium, Bradyrhizobium, Sinorhizobium, Azorhizobium, Agrobacterium, and Phyllobacterium. A seventh genus, Mesorhizobium, has been proposed recently (Jarvis et al., 1997; Young and Haukka, 1996).

Molecular Evolutionary Systematics of the Rhizobiaceae

1998
The plant family Fabaceae (the Legume family), subdivided into three subfamilies, Mimosoideae, Ceasalpinioideae, and Papilionoideae, contains 674 genera (Gunn et al., 1992) with an estimated 16,000 to 19,000 species (Allen and Allen, 1980). The Fabaceae have worldwide distribution and their economic importance is second only to the Poaceae (the Grass ...

Attachment of Rhizobiaceae to Plant Cells

1998
Rhizobiaceae are a family of free-living soil bacteria. Thanks to special properties, these bacteria can escape from poor soil conditions by spending a part of their lifetime in or on a plant. During this stage of life, many of them are attached to the surface of plant cells.

Leech mycetome endosymbionts are a new lineage of alphaproteobacteria related to the Rhizobiaceae

Molecular Phylogenetics and Evolution, 2004
Mycetomal organs attached to the esophagus of hematophagous leeches which are known to harbor endosymbiotic bacteria were removed from three species in the leech family Glossiphoniidae. Anatomical observations indicated that placobdellid mycetomes are paired and caecate, inserting into the esophagus posterior to the proboscis.

Taxonomy of rhizobia and agrobacteria from the Rhizobiaceae family in light of genomics

Systematic and Applied Microbiology, 2015
Phylogenomic analyses showed two major superclades within the family Rhizobiaceae that corresponded to the Rhizobium/Agrobacterium and Shinella/Ensifer groups. Within the Rhizobium/Agrobacterium group, four highly supported clades were evident that could correspond to distinct genera.

The Rhizobiaceae Bacteria Transferring Genes to Higher Plants

2019
The family Rhizobiaceae includes several bacterial genera able to induce root or stem nodules, which can be beneficial for the plant, or hypertrophies, such as tumours, which cause plant damage. The members from genus Agrobacterium are well known by their ability to transfer genes to different plants originating tumours, and this feature has been ...

Unusual organization of the 23S rRNA genes in the Rhizobiaceae

Soil Biology and Biochemistry, 1997
Abstract The presence of intervening sequences (IVSs) in the 23S rRNA genes of rhizobia and the phenomenon of fragmentation of their matured 23S-like rRNA molecules are analysed. A novel IVS-IVS II, in the 23S rRNA gene of several rhizobial strains is described, which is located approximately at position 540 bp ( E. coli numeration).

Sequence Diversity of the Plasmid Replication Gene repC in the Rhizobiaceae

Plasmid, 2000
The repABC operon is essential for stable maintenance of some Rhizobiaceae plasmids and of pTAV320 from Paracoccus versutus. These plasmids are the largest described family of homologous, yet compatible replicons. The repC gene is essential for plasmid replication, and previous work identified four distinct sequence groups (repC1, repC2, repC3, and ...
