Enhanced Symbiotic Performance by Rhizobium tropici Glycogen Synthase Mutants [PDF]
, 2001 We isolated a Tn5-induced Rhizobium tropici mutant that has enhanced capacity to oxidize N,N-dimethyl-p-phenylendiamine (DMPD) and therefore has enhanced respiration via cytochrome oxidase.

Environmental Microbiology, Volume 27, Issue 1, January 2025.Legumes release flavonoids into the soil, which are detected by the rhizobial NodD protein, initiating the transcription of nod genes for Nod Factors (NF) synthesis. We found that removing the NodD regulatory domain results in a constantly active protein (NodDFI), which independently activates NF biosynthesis genes without flavonoids. ABSTRACT Rhizobia

Ameba-associated Microorganisms and Diagnosis of Nosocomial Pneumonia
Emerging Infectious Diseases, 2006 To elucidate the role of ameba-associated microorganisms (AAMs) as etiologic agents of pneumonia, we screened for Legionella spp., Parachlamydia acanthamoeba, Afipia sp., Bosea spp., Bradyrhizobium spp., Mesorhizobium amorphae, Rasbo bacterium ...

Environmental Microbiology, Volume 26, Issue 2, February 2024.Plant–microbe interactions are strongly influenced by chemically complex root exudates. Using the rhizobia‐legume symbiosis as model system, we demonstrate the importance of motility and chemotaxis at different stages, such as rhizobial competition or nodulation dynamics and development.

Nod factors thin-layer chromatography profiling as a tool to characterize symbiotic specificity of rhizobial strains : application to Sinorhizobium saheli, S. teranga, and Rhizobium sp. strains isolated from Acacia and Sesbania [PDF]
, 1996 Rhizobia isolated from #Acacia$ or #Sesbania$ belong to several taxonomic groups, including the newly described species #Sinorhizobium saheli$, #Sinorhizobium teranga$, and the so-called cluster U.

Frontiers in Plant Science, 2016 Several studies have shown that plant hormones play important roles during legume-rhizobia symbiosis. For instance, auxins induce the formation of nodule-like structures (NLS) on legume roots in the absence of rhizobia.

Evidence for functional differentiation of duplicatednifHgenes inAzorhizobium caulinodans [PDF]
FEMS Microbiology Letters, 2007 Azorhizobium caulinodans is a symbiotic diazotroph that contains duplicated nifH genes. This study focused on the biological sense behind the duplication. In-frame deletion mutants of nifH1 and nifH2 were constructed in order to analyze nitrogen fixation activity, both in symbiosis and in free-living conditions. Symbiotic nitrogen fixation activity was

Nod Factor Perception During Infection Thread Growth Fine-Tunes Nodulation
Molecular Plant-Microbe Interactions, 2007 Bacterial nodulation factors (NFs) are essential signaling molecules for the initiation of a nitrogen-fixing symbiosis in legumes. NFs are perceived by the plant and trigger both local and distant responses, such as curling of root hairs and cortical ...
