GuaB Activity Is Required in Rhizobium tropici During the Early Stages of Nodulation of Determinate Nodules but Is Dispensable for the Sinorhizobium meliloti–Alfalfa Symbiotic Interaction [PDF]
, 2005 The guaB mutant strain Rhizobium tropici CIAT8999-10T is defective in symbiosis with common bean, forming nodules that lack rhizobial content. In order to investigate the timing of the guaB requirement during the nodule formation on the host common ...

Causes and consequences of bacterial local adaptation via MGEs in the plant microbiome
New Phytologist, EarlyView.Summary Adaptations that enable plant‐associated bacteria to fill disparate niches comprise a critical component of microbial diversity. Genes that confer locally adaptive bacterial traits, ranging from heavy metal resistance to pathogen or symbiont infectivity, often reside within mobile genetic elements (MGEs) that can move between genomes.

Roles of Predicted Glycosyltransferases in the Biosynthesis of the Rhizobium etli CE3 O Antigen [PDF]
, 2013 The Rhizobium etli CE3 O antigen is a fixed-length heteropolymer. The genetic regions required for its synthesis have been identified, and the nucleotide sequences are known.

Expression of Rhizobium meliloti nod genes in Rhizobium and Agrobacterium backgrounds [PDF]
Journal of Bacteriology, 1987 Rhizobium meliloti nod genes are required for the infection of alfalfa. Induction of the nodC gene depends on a chemical signal from alfalfa and on nodD gene expression. By using a nodC-lacZ fusion, we have shown that the induction of the R. meliloti nodC gene and the expression of nodD occur at almost normal levels in other Rhizobium backgrounds and ...

Rhizobial motility preference in root colonization of Medicago truncatula
New Phytologist, EarlyView.Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

BacS: An Abundant Bacteroid Protein in \u3cem\u3eRhizobium etli\u3c/em\u3e Whose Expression Ex Planta Requires \u3cem\u3enifA\u3c/em\u3e [PDF]
, 2003 Rhizobium etli CFN42 bacteroids from bean nodules possessed an abundant 16-kDa protein (BacS) that was found in the membrane pellet after cell disruption. This protein was not detected in bacteria cultured in tryptone-yeast extract.

Microbiological Reviews, 1995 Rhizobium, Bradyrhizobium, and Azorhizobium species are able to elicit the formation of unique structures, called nodules, on the roots or stems of the leguminous host. In these nodules, the rhizobia convert atmospheric N2 into ammonia for the plant. To establish this symbiosis, signals are produced early in the interaction between plant and rhizobia ...

Conserved Nodulation Genes in Rhizobium meliloti and Rhizobium trifolii [PDF]
Applied and Environmental Microbiology, 1985 Plasmids which contained wild-type or mutated Rhizobium meliloti nodulation ( nod ) genes were introduced into Nod − R. trifolii mutants ANU453 and ANU851 and tested for their ability to nodulate clover. Cloned wild-type and mutated R.
