Abiotic stress significantly limits plant growth and production. Drought, in particular, is a severe constraint that affects agricultural productivity on global scale. Water induces plants set of morpho-anatomical (modification root leaf structure), physiological, biochemical (relative water content, membrane stability, photosynthesis, hormonal balance, antioxidant systems, osmolyte accumulation) changes mainly employed to cope with the drought stress. These strategies allow overcome unfavorable period limited availability. Currently, promising alternative available improve tolerance under conditions. The use osmotolerant growth-promoting rhizobacteria (PGPR) as inoculants can alleviate by increasing efficiency plant. PGPR drought, through morphology architecture system, production phytohormones, extracellular polysaccharides, ACC 1-(aminocyclopropane-1-carboxylate) deaminase, volatile chemicals, accumulation.

Salicylic acid (SA) and proline exhibit protective effects against a wide range of stresses. However, the combined impact SA on rice under drought stress is still unknown. Therefore, we investigated roles and/or in conferring tolerance rice. There were eight treatments comprising control (T1; 95-100% FC), 1.5 mM (T2), 2 (T3), 0.75 + 1 (T4), 45-50% FC (T5, stress), T5 (T6), (T7), (T8), two varieties: BRRI dhan66 dhan75. Drought significantly decreased plant growth, biomass, yield attributes, photosynthetic rate (Pn), stomatal conductance (gs), transpiration (Tr), pigments (chlorophyll carotenoids content), relative water content (RWC), membrane stability index (MSI), soluble sugar starch content, uptake N, P K+ roots shoots. Drought-induced oxidative form increased hydrogen peroxide (H2O2) production lipid peroxidation (MDA) was observed.

Drought poses a significant challenge, restricting the productivity of medicinal and aromatic plants. The strain induced by drought can impede vital processes like respiration photosynthesis, affecting various aspects plants' growth metabolism. In response to this adversity, plants employ mechanisms such as morphological structural adjustments, modulation drought-resistant genes, augmented synthesis secondary metabolites osmotic regulatory substances alleviate stress. Extreme water scarcity lead leaf wilting may ultimately result in plant death. cultivation management under stress conditions often differ from those other crops. This is because main goal with not only increase yield above-ground parts but also enhance production active ingredients essential oils. To elucidate these resistance plants, current review provides summary recent literature encompassing studies on morphology, physiology, biochemistry conditions.
