A Novel Module Promotes Horizontal Gene Transfer in Azorhizobium caulinodans ORS571. [PDF]
Genes (Basel), 2022 Azorhizobium caulinodans ORS571 contains an 87.6 kb integrative and conjugative element (ICEAc) that conjugatively transfers symbiosis genes to other rhizobia. Many hypothetical redundant gene fragments (rgfs) are abundant in ICEAc, but their potential function in horizontal gene transfer (HGT) is unknown.

Azorhizobium caulinodans Chemotaxis Is Controlled by an Unusual Phosphorelay Network. [PDF]
J Bacteriol, 2022 Chemotaxis allows bacteria to move toward nutrients and away from toxins in their environment. Chemotactic movement provides a competitive advantage over nonspecific motion.

IDENTIFICATION AND CHARACTERIZATION OF A FUNCTIONAL NODD GENE IN AZORHIZOBIUM-CAULINODANS ORS571 [PDF]
Journal of Bacteriology, 1990 Azorhizobium caulinodans ORS571, a bacterium capable of nodulating roots and stems of the tropical legume Sesbania rostrata, has been shown to have no nodD-like gene located immediately upstream from its common nodABC locus. A clone carrying a functional nodD gene of strain ORS571 has now been isolated from a pLAFR1 gene library by screening for ...

Responses of Azorhizobium caulinodans to cadmium stress [PDF]
FEMS Microbiology Ecology, 2005 The symbiosis of Azorhizobium caulinodans and an annul legume Sesbania rostrata was recently found to be tolerant to cadmium pollution by an unknown mechanism. In this study, A. caulinodans ORS571 and ZY-20 showed much stronger tolerance to cadmium than a mutant ORS571-X15 and a common Rhizobium sp., with minimum inhibitory concentration values as high

A Chemotaxis Receptor Modulates Nodulation during the Azorhizobium caulinodans-Sesbania rostrata Symbiosis. [PDF]
Appl Environ Microbiol, 2016 ABSTRACT Azorhizobium caulinodans ORS571 is a free-living nitrogen-fixing bacterium which can induce nitrogen-fixing nodules both on the root and the stem of its legume host Sesbania rostrata .

Functional analysis of the fixNOQP region of Azorhizobium caulinodans [PDF]
Journal of Bacteriology, 1994 The deduced amino acid sequences of four open reading frames identified upstream of the fixGHI region in Azorhizobium caulinodans are very similar to the putative terminal oxidase complex coded by the fixNOQP operons from Rhizobium meliloti and Bradyrhizobium japonicum. The expression of the A.

Plant nodulation inducers enhance horizontal gene transfer of Azorhizobium caulinodans symbiosis island. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Pathogenic or symbiosis islands are mobile genetic elements that can provide recipient bacteria the capacity to establish intimate interactions with eukaryotic hosts. For example, legume symbionts have evolved via horizontal transfer of symbiotic plasmids or genomic islands.

Identification of cyclic intermediates in Azorhizobium caulinodans nicotinate catabolism [PDF]
Journal of Bacteriology, 1989 In wild-type Azorhizobium caulinodans ORS571, nicotinate served both as anabolic substrate for NAD+ production and as catabolic substrate for use as the N source. Catabolic enzyme activities were greatest from cultures grown with nicotinate as the N source and least when cultures were grown with ammonium as the N source. Vector insertion mutants unable

Azorhizobium caulinodans respires with at least four terminal oxidases [PDF]
Journal of Bacteriology, 1994 In culture, Azorhizobium caulinodans used at least four terminal oxidases, cytochrome aa3 (cytaa3), cytd, cyto, and a second a-type cytochrome, which together mediated general, respiratory electron (e-) transport to O2. To genetically dissect physiological roles for these various terminal oxidases, corresponding Azorhizobium apocytochrome genes were ...

The Hypoxia-Associated Localization of Chemotaxis Protein CheZ in Azorhizorbium caulinodans
Frontiers in Microbiology, 2021 Spatial organization of chemotactic proteins is important for cooperative response to external stimuli. However, factors affecting the localization dynamics of chemotaxis proteins are less studied.
