Xylem colonization of tomato by azorhizobium caulinodans ORS571 [PDF]
Tomato seedlings growing aseptically in Murashige and Skoog Medium were inoculated with Azorhizobium caulinodans ORS571 (pXLGD4), carrying the lacZ reporter gene. By microscopic analyses of inoculated tomato roots, it has been demonstrated that the xylem of tomato roots can be colonized by Azorhizobium. We discuss whether this colonization of the xylem

Symbiotic legume nodules employ both rhizobial exo- and endo-hydrogenases to recycle hydrogen produced by nitrogen fixation. [PDF]
BACKGROUND: In symbiotic legume nodules, endosymbiotic rhizobia (bacteroids) fix atmospheric N(2), an ATP-dependent catalytic process yielding stoichiometric ammonium and hydrogen gas (H(2)).

Role and Regulation of Poly-3-Hydroxybutyrate in Nitrogen Fixation in Azorhizobium caulinodans
An Azorhizobium caulinodans phaC mutant (OPS0865) unable to make poly-3-hydroxybutyrate (PHB), grows poorly on many carbon sources and cannot fix nitrogen in laboratory culture.

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]
The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...

Patterns of Pectin Methylesterase Transcripts in Developing Stem Nodules of Sesbania rostrata
Differential display was applied to the early stages of the interaction between the tropical legume Sesbania rostrata and its microsymbiont Azorhizobium caulinodans ORS571.

Calcium spiking patterns and the role of the calcium/calmodulin-dependent kinase CCaMK in lateral root base nodulation of Sesbania rostrata [PDF]
Nodulation factor (NF) signal transduction in the legume-rhizobium symbiosis involves calcium oscillations that are instrumental in eliciting nodulation.

Identification of a New Inducible Nodulation Gene inAzorhizobium caulinodans
The narrow host range bacterial strain Azorhizobium caulinodans ORS571 induces the formation of nitrogen-fixing nodules on the root and stem of the tropical legume Sesbania rostrata. Here, a new flavonoid-inducible locus of ORS571 is described, locus 4.

7,4'-Dihydroxyflavanone is the major Azorhizobium nod gene-inducing factor present in Sesbania rostrata seedling exudate [PDF]
Exudate from Sesbania rostrata seedlings contains signaling compounds that induce the common nodABC operon of the bacterial symbiont Azorhizobium caulinodans ORS571.
