MetabolomicsLegume rhizodeposition promotes nitrogen fixation by soil microbiota under crop diversification

Biological nitrogen fixation by free-living bacteria and rhizobial symbiosis with legumes plays a key role in sustainable crop production. Here, we study how different crop combinations influence the interaction between peanut plants and their rhizosphere microbiota via metabolite deposition and ...

MetabolomicsArsenic-induced enhancement of diazotrophic recruitment and nitrogen fixation in Pteris vittata rhizosphere
Heavy metal contamination poses an escalating global challenge to soil ecosystems. Hyperaccumulators play a crucial role in environmental remediation and resource recovery. The enrichment of diazotrophs and resulting nitrogen accumulation promoted hyperaccumulator growth and facilitated phytoremedia...

MetabolomicsCoupled nitrogen fixation and substrate stabilization drive ecological strategy shifts during microbial succession

Background:

Primary succession is predicted to proceed through shifts from stress-tolerant to competitive to cooperative ecological strategies as resource availability increases, yet molecular evidence for these transitions in microbial systems remains limited. Here, we used an integrated m...

TranscriptomicsRhizobium etli CFN42 wild type transcriptional profiling was compared between free living and symbiosis conditions
Rhizobium etli is a bacteria that fix nitrogen in symbiotic activity with Phaseolus vulgaris, the common bean plant. In order to accomplish this nitrogen reduction a especial environment is induced in nodules such that gene expression of bacteroid suffer a significant change with respect to its wild...

TranscriptomicsTranscription profiling of G sulfurreducens GGS nitrogen fixation
G. sulfurreducens (ATCC #51573) was obtained from the laboratory culture collection of Dr. Derek Lovley. Cells were grown under strict anaerobic conditions at 30 °C in chemostats, as previously described (for more information see Esteve-Núñez, A., M. M. Rothermich, M. Sharma, and D. R. Lovley. 2004....

ProteomicsProteomic analysis dissects the impact of nodulation and biological nitrogen fixation on Vicia faba root nodule physiology
Symbiotic nitroegn fixation in functional (Fix+) and non-functional (Fix-) nodules of Vicia faba infected with Rhizobium leguminosarum was investigated using label-free shotgun tandem MS. Proteins involved in symbiotic nitrogen fixation and maintenance of the symbiosis were identified.

TranscriptomicsOverproduction of indole-3-acetic acid in free-living rhizobia mimics physiological conditions required for nitrogen fixation inside root nodules
Background: The overproduction of the main auxin indole-3-acetic acid (IAA) in Sinorhizobium meliloti RD64 leads to beneficial effects both in free-living rhizobium and in host plant during symbiosis. These effects could be related to alteration in gene expression induced by IAA. Preliminary studies...
