Effect of microbial biofertilizer on proteomic profiling, antioxidant enzyme and andrographolide content in Andrographis paniculata Burm.f Nee. under drought stress

Microbial biofertilizers were investigated for their ability to mitigate drought stress and enhance resilience in Andrographis paniculata. High-performance liquid chromatography (HPLC) analysis revealed that microbial biofertilizer significantly increased andrographolide content, a key bioactive compound, even under drought stress.
