Maize (Zea mays) is India's third-largest grain crop, serving as a primary food source for at least 30% of the population and sustaining 900 million impoverished people globally. The growing human has led to an increasing demand maize grains. However, cultivation faces significant challenges due variety environmental factors, including both biotic abiotic stresses. Abiotic stresses such salinity, extreme temperatures, drought, along with factors like bacterial, fungal, viral infections, have drastically reduced production quality worldwide. interaction between these complex; instance, stress can heighten plant's susceptibility pathogens, while overabundance pests exacerbate response stress. Given complexity interactions, comprehensive studies are crucial understanding how simultaneous presence affects crop productivity. Despite importance this issue, there lack data on combinations impact in key agricultural regions. This review focuses developing stress-tolerant varieties, which will be essential maintaining yields future. One promising approach involves use Plant Growth-Promoting Rhizobacteria (PGPR), soil bacteria that colonize rhizosphere interact plant tissues. Scientists increasingly exploring microbial strategies enhance maize's resistance Throughout process, insect microorganisms pose threats maize, diminishing quantity grain. Among various causing degradation, insects most prevalent, followed by fungal infections. also delves into latest advancements applying beneficial rhizobacteria across different agroecosystems, highlighting current trends offering insights future developments under normal conditions.

Drought and heat stress often co-occur in nature, their combined effects are a major driver of crop losses, causing more severe damage to plant metabolism than when they occur individually. This study investigates the responses three edamame cultivars (AGS429, UVE14, UVE17) drought (DH) stress, with emphasis on reactive oxygen species (ROS), antioxidative mechanisms cell wall modifications. Malondialdehyde (MDA), electrolyte leakage (EL), hydrogen peroxide (H2O2) were used measure oxidative membrane damage. The non-enzymatic (ascorbic acid, AsA) enzymatic (superoxide dismutase, ascorbate peroxidase (APX), guaiacol peroxidase, glutathione reductase) antioxidant determined spectrophotometrically. Cell biomass composition (cellulose, hemicellulose, lignin, phenols) was using Fourier transform Infrared Spectroscopy spectrophotometry. Ascorbate activity AsA content DH-stressed AGS429 at flowering strongly correlated reduced lipid peroxidation (r2 = -0.97 - 0.98). Cultivar UVE14 accumulated high under DH both growth stages, which, turn, positively associated total phenolic 0.97), APX activity, holocellulose, suggesting enhanced ROS-dependent polymerisation. On contrary, poor ROS quenching UVE17 led MDA accumulation (p ≤ 0.05), leading EL cellulose synthesis pod-filling -0.88). Therefore, physio-biochemical level, showed tolerance through modifications, while susceptible. Identifying key biochemical traits linked offers novel insights for breeding resilient cultivars.
