Metabolic data of the first leaf (L1) and the third leaf (L3) of two oat (Avena sativa) cultivars: DY5 (stress sensitive) and BY14 (stress tolerant) at 52 days post sowing (DPS) under saline-alkali stress (implicated at 37 DPS).

Bacillus siamensis to restore the compromised amino acid and energy metabolism of Mesorhizobium metallidurans under saline alkali stress

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...

These findings suggest that B. siamensis BT 9 1 cross-feeds M. metallidurans YC-39 with these metabolites, rescuing the compromised branched-chain amino acid synthesis pathway and the TCA cycle in saline alkaline environments. Eventually, coinoculation with B. siamensis BT 9 1 and M. metalliduran...

Combined saline-alkali and cold stresses severely constrain plant growth at middle and high latitudes. Plants have evolved cross-adaptation mechanisms wherein exposure to one stress enhances resistance to another. However, the specific mechanisms driving cross-adaptation between saline-alkali and...

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...
