Unlabelled: has numerous two-component signaling systems (TCSs), many of which regulate the complex social behaviors of this soil bacterium. A subset of TCSs consists of NtrC-like response regulators (RRs) and their cognate histidine sensor kinases (SKs). We have previously demonstrated that a multi-component, phosphorelay TCS named NmpRSTU plays a role in social motility.

Soil salinization adversely impacts plant and soil health. While amendment with chemicals is not sustainable, the application of bioinoculants suffers from competition with indigenous microbes. Hence, microbiome-based rhizosphere engineering, focussing on acclimatization of rhizosphere microbiome under selection pressure to facilitate plant growth, exhibits promise.

To investigate the role of the RegSR-NifA regulatory cascade in the oxygen control of nitric oxide (NO) reduction in the soybean endosymbiont . We have performed an integrated study of expression and NO reductase activity in , , , , and mutants in response to microoxia (2% O) or anoxia. An activating role of RegR and NifA was observed under anoxia.

The effects of rhizosphere microorganisms on plant growth and the associated mechanisms are a focus of current research, but the effects of exogenous combined inoculation with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) on seedling growth and the associated rhizosphere microecological mechanisms have been little reported. In this study, a greenhouse pot experiment was used to study the effects of single or double inoculation with AM fungi () and two PGPR ( sp., sp.

The imbalanced soil nutrient status caused by the long-term monoculture of flue-cured tobacco are a concern. The tobacco-maize relay intercropping, widely used in Yunnan, may improve soil nutrients by enhancing the soil microbial community, but this remains unexplored. This study employed high-throughput sequencing technology to examine soil microbial diversity under tobacco monoculture and tobacco-maize relay intercropping, using the varieties Hongda and K326, respectively.
