Signal Mediators in the Implementation of Jasmonic Acid’s Protective Effect on Plants under Abiotic Stresses

Abstract

Plant cells respond to stress by activating signaling and regulatory networks that include plant hormones and numerous mediators of non-hormonal nature. These include the universal intracellular messenger calcium, reactive oxygen species (ROS), gasotransmitters, small gaseous molecules synthesized by living organisms, and signal functions such as nitrogen monoxide (NO), hydrogen sulfide (H2S), carbon monoxide (CO), and others. This review focuses on the role of functional linkages of jasmonic acid and jasmonate signaling components with gasotransmitters and other signaling mediators, as well as some stress metabolites, in the regulation of plant adaptive responses to abiotic stressors. Data on the involvement of NO, H2S, and CO in the regulation of jasmonic acid formation in plant cells and its signal transduction were analyzed. The possible involvement of the protein components of jasmonate signaling in stress-protective gasotransmitter effects is discussed. Emphasis is placed on the significance of the functional interaction between jasmonic acid and signaling mediators in the regulation of the antioxidant system, stomatal apparatus, and other processes important for plant adaptation to abiotic stresses.

Preharvest Elicitors as a Tool to Enhance Bioactive Compounds and Quality of Both Peel and Pulp of Yellow Pitahaya (Selenicereus megalanthus Haw.) at Harvest and during Postharvest Storage

“…Methyl jasmonate (MeJA) is a volatile hormone derived from jasmonic acid involved in a wide range of plant functions, acting as a signal in response to abiotic stresses and modulating the biosynthesis of other plant growth regulators [31,32]. Plants synthesize this hormone in defence against biotic and abiotic stresses but also modulate fruit growth and ripening [33]. The higher TA and firmness and the lower TSS in MeJA-treated pitahaya may be attributed to the ripening-retarding effects of MeJA and a delay in the senescence process.…”

Nitric Oxide: Functional Interaction With Phytohormones and Applications in Crop Production

“…Jasmonic acid (JA) is a phytohormone involved in the regulation of plant resistance to biotic (primarily necrotrophic pathogens and insect pests) and many abiotic stressors (Wasternack, 2007;Santino et al, 2013;Wasternack, Hause 2013;Kolupaev et al, 2023b).…”

“…The mechanisms of NO synthesis through minor pathways also remain unclear, as well as how these pathways contribute to NO signaling functions (Saha et al, 2015;Kumar, Ohri, 2023). In recent years, much attention has been paid to the functional interaction of nitric oxide with phytohormones, which is associated with its participation in transmitting hormonal signals to the genetic apparatus, as well as its ability to induce the formation of signals that activate the synthesis of some phytohormones (Singhal et al, 2021;Shang et al, 2022;Kolupaev et al, 2023b;Ullah et al, 2024). The mechanisms of such phenomena are still poorly understood and information about them is scattered.…”

Response of Wheat Seedlings With Different Drought Tolerance to Melatonin Action Under Osmotic Stress

“…In addition to the classical "drought hormone" abscisic acid (ABA) (Jogawat et al, 2021), the role of other groups of hormones-salicylic acid (Singh et al, 2021;Rouhnezhad et al, 2023), jasmonates (Kolupaev et al, 2023b), and brassinosteroids (Ribeiro et al, 2019) -in drought adaptation has been intensively studied over the past two decades. Also in recent years, knowledge of the plant functions of neurotransmitters, which were previously discovered and studied in mammals, has been intensively accumulated.…”
