Biosynthesis and function of rhizobacterial secondary metabolites in plant abiotic stress tolerance

Rhizobacterial strains (RK1, RT2, RT3) produced diverse bioactive secondary metabolites detected by GC-MS. Proline was the most abundant metabolite, acting as a key osmoprotectant under drought stress. RT3 strain significantly enhanced lettuce drought tolerance compared to other treatments. Inoculated plants showed higher survival rates and fresh biomass after rewatering. Specific metabolites such as proline, glycine, and vitamins contributed to improved plant stress resilience.

Abstract

Rhizobacterial strains (RK1, RT2, RT3) produced diverse bioactive secondary metabolites detected by GC-MS. Proline was the most abundant metabolite, acting as a key osmoprotectant under drought stress. RT3 strain significantly enhanced lettuce drought tolerance compared to other treatments. Inoculated plants showed higher survival rates and fresh biomass after rewatering. Specific metabolites such as proline, glycine, and vitamins contributed to improved plant stress resilience.
