TLDR Enterobacter sp. SA187 helps tomato plants grow better in salt and heat by boosting stress-related responses.
The study shows that inoculating tomato plants with Enterobacter sp. SA187 significantly improves their growth and tolerance to salt and heat stress. SA187-colonized plants exhibit increased biomass, better ion balance, higher chlorophyll content, and enhanced antioxidant enzyme activity. Under salt stress, leaf weights increased by over 97%, and under heat stress, by over 68%. The Na+/K+ ratio improved, and chlorophyll content rose by over 41% under salt stress and 65% under heat stress. Gene expression analysis revealed upregulation of stress-related genes, indicating that SA187 enhances stress tolerance by modulating gene expression and physiological responses. This suggests SA187's potential as a biostimulant for improving crop tolerance and productivity in challenging environments.
