Due to global climate change, abiotic stresses are affecting plant growth, productivity, and the quality of cultivated crops. Stressful conditions disrupt physiological activities suppress defensive mechanisms, resulting in stress-sensitive plants. Consequently, plants implement various endogenous strategies, including hormone biosynthesis (e.g., abscisic acid, jasmonic salicylic brassinosteroids, indole-3-acetic cytokinins, ethylene, gibberellic strigolactones) withstand stress conditions. Combined or single disrupts normal transportation solutes, causes electron leakage, triggers reactive oxygen species (ROS) production, creating oxidative Several enzymatic non-enzymatic defense systems marshal a plant’s antioxidant defenses. While responses protective role system have been well-documented recent investigations, interrelationships among hormones, neurotransmitters (NTs, such as serotonin, melatonin, dopamine, acetylcholine, γ-aminobutyric acid), defenses not well explained. Thus, this review discusses advances transgenic metabolic developments, potential interaction hormones with NTs response tolerance mechanisms. Furthermore, we discuss current challenges future directions (transgenic breeding genome editing) for improvement using modern molecular tools. The involved regulating systems, networks, abiotic-induced also discussed.

Climate change and abiotic stress factors are key players in crop losses worldwide. Among which, extreme temperatures (heat cold) disturb plant growth development, reduce productivity and, severe cases, lead to death.
