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.

Beitr�ge zur Taxonomie der Rhizobiaceae
Archiv f�r Mikrobiologie, 1968Durch Anwendung der DNA-DNA-Hybridisierungsmethode von McCarthy u. Bolton (1963) werden verwandtschaftliche Beziehungen zwischen der Gattung Agrobacterium und Rhizobium nachgewiesen. Auserdem ergeben sich Hinweise, die taxonomische Affinitaten einiger Blattsymbionten in Rubiaceae zu den Rhizobiaceae vermuten lassen.

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).

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

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.

Leech mycetome endosymbionts are a new lineage of alphaproteobacteria related to the Rhizobiaceae
Molecular Phylogenetics and Evolution, 2004Mycetomal 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.

Plasmids of the Rhizobiaceae and Their Role in Interbacterial and Transkingdom Interactions
2010Bacteria belonging to the Rhizobiaceae have more than a century now attracted scientific attention due to their ability to associate with plants and drastically affect plant development or well-being. Major role in the plant – microbe exchange that acts in host benefit or disease is played by indigenous plasmids of the bacteria, usually large in size ...

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 ...
