Phytohormones as Growth Regulators During Abiotic Stress Tolerance in Plants

Phytohormones (PHs) play crucial role in regulation of various physiological and biochemical processes that govern plant growth yield under optimal stress conditions. The interaction these PHs is for survival stressful environments as they trigger signaling pathways. Hormonal cross initiate a cascade reactions which finely tune the architecture help to grow suboptimal Recently, studies have highlighted such abscisic acid, salicylic ethylene, jasmonates responses toward environmental stresses. involvement cytokinins, gibberellins, auxin, relatively novel strigolactones brassinosteroids development has been documented normal recent identification first melatonin receptor opened door this regulatory molecule being considered new hormone. However, polyamines, are not PHs, included chapter. Various microbes produce secrete hormones helped plants nutrient uptake N, P, Fe. Exogenous use correcting deficiency abiotic This chapter focused on developments knowledge related their stresses anticipation, signaling, cross-talk, activation response mechanisms. In view capability producing hormones, we propose potential strategy crop management.
