Molecular Evolutionary Systematics of the Rhizobiaceae
1998The 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
1998Rhizobiaceae 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.

Antonie van Leeuwenhoek, 1998
We demonstrated that the representatives of the family Rhizobiaceae possess, instead of one single 23S rRNA molecule, three different sets of 23S-like rRNA fragments with sizes of about: 135 b and 2.6 kb (set 1); 135 b, 400 b, and 2.2 kb (set 2); 135 b and two molecules of about 1.3 kb (set 3). In two of the fragmentations, intervening sequences--IVS I

Sequence Diversity of the Plasmid Replication Gene repC in the Rhizobiaceae
Plasmid, 2000The 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 ...

The Symbiotic Plasmids of theRhizobiaceae
2014The Leguminosae, with around 18,000 species, is the largest plant family on Earth; its ecological success owes much to the existence of nitrogen-fixing symbioses with prokaryotes. These symbioses occur mainly with members of the Rhizobiaceae family (belonging to the a-proteobacteria).

Unusual organization of the 23S rRNA genes in the Rhizobiaceae
Soil Biology and Biochemistry, 1997Abstract 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).

The Rhizobiaceae Bacteria Transferring Genes to Higher Plants
2019The 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 ...

Taxonomy of rhizobia and agrobacteria from the Rhizobiaceae family in light of genomics
Systematic and Applied Microbiology, 2015Phylogenomic 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.

[Lipopolysaccharides of rhizobiaceae: structure and biosynthesis].
Revista latinoamericana de microbiologia, 2007The lipopolysaccharides (LPS) are major components of the outer membrane of Gram negative bacteria and, because of their location, are important mediators in the interaction between these bacteria and their environment and other organisms. The alpha-Proteobacterial family Rhizobiaceae includes the rhizobia and agrobacteria, microorganisms which ...

Opines and Opine-Like Molecules Involved in Plant-Rhizobiaceae Interactions
1998The first reports on opines date back to the midfifties, when Morel (1956) and Lioret (1956) independently presented their results on, respectively, the metabolism of arginine and the identification of unusual amino acids in Agrobacterium-induced crown gall tumors, at a meeting of the French Society for Plant Physiology.
