“…), hydrogen peroxide (H 2 O 2 ), and hydroxyl radicals (HO • ) injuring the chloroplasts and mitochondria, is a significant indicator of oxidative damage in salinity [34]. These ROS disrupt the membranous structure and its cell permeability; thus, nutrient availability is reduced under salinity stress [35].…”

Plants undergo a wide range of morphological, cellular, anatomical, and physiological changes in response to salinity stress. However, plants produce some signaling molecules, usually known as phytohormones, to combat stress conditions. Salinity tolerance is a complex mechanism, whereas phytohormones have a central role in it. Phytohormone-mediated plant responses improve nutrient uptake, the source-sink relationship, and plant growth and development. Phytohormones triggers the specific gene expressions which are responsible for the modification of various plant mechanisms under salinity stress. This review summarized the most recent research findings about plant responses to salinity stress at physiological and molecular levels and discussed the probable function of several (abscisic acid, indole acetic acid, cytokinins, gibberellic acid, salicylic acid, brassinosteroids, ethylene, and triazoles) phytohormones and their interaction in modulating salinity stress. Further, the understanding of specific genes involved in phytohormonal regulation toward salinity tolerance is a key to developing breeding and transgenic approaches for meeting food demand under sustainable crop production.

Gamma-aminobutyric acid (GABA), a ubiquitous non-protein 4-carbon amino acid present in both prokaryotic and eukaryotic organisms. It is conventionally recognized as a neurotransmitter in mammals and plays a crucial role in plants. The context of this review centers on the impact of GABA in mitigating abiotic stresses induced by climate change, such as drought, salinity, heat, and heavy metal exposure. Beyond its neurotransmitter role, GABA emerges as a key player in diverse metabolic processes, safeguarding plants against multifaceted abiotic as well as biotic challenges. This comprehensive exploration delves into the GABA biosynthetic pathway, its transport mechanisms, and its intricate interplay with various abiotic stresses. The discussion extends to the nuanced relationship between GABA and phytohormones during abiotic stress acclimation, offering insights into the strategic development of mitigation strategies against these stresses. The delineation of GABA's crosstalk with phytohormones underscores its pivotal role in formulating crucial strategies for abiotic stress alleviation in plants.
