Soil salinization severely restricts the growth and yield of crops. It is particularly urgent to find safe and effective measures to reduce soil salinity, improve the soil nutrient environment and achieve the improvement of saline-alkali soil. Beneficial microorganisms in the rhizosphere can acti...
Carbonate-type saline-alkaline stress severely constrains maize production; however, the synergistic response mechanisms between rhizosphere microorganisms and metabolites remain unclear. This study focused on maize fields in the carbonate chernozem region of the Songnen Plain in Northeast China....
Background
Soil salinization and alkalization severely threaten soybean growth and yield. Arbuscular mycorrhizal fungi (AMF), specifically Rhizophagus intraradices (Ri), enhance stress tolerance and soil quality, yet their mechanisms in regulating microbial-metabolite interactions during cr...
Metabolomics analysis revealed specific accumulation of amino acids, organic acids, carbohydrates, fatty acids and flavonoids in ZD compared with that in BM. The core differential metabolites associated with ZD stress resistance included isoleucine, fumaric acid, raffinose and isovitexin. In...
Diazotrophic cyanobacteria have a pivotal role in nitrogen fixation and soil fertility in paddy ecosystems, yet their responses to soil acidity stress (SAS) remain elusive. This study investigated the physiological and metabolic mechanisms underlying acid tolerance in diazotrophic cyanobacteria b...
