Jasmonic acid (JA) or methyl jasmonate (MeJA) are master regulators of plant development and stress response against pathogens and environmental fluctuations. Thus, JA is an important stress-associated phytohormone that can promote various defense interactions, regulate stomatal openness, synthesis of antimicrobial substances, or plant cell reprogramming. Numerous studies also demonstrated that plants thriving under environmental fluctuations stresses are linked to the JA response, revealing that JA application can alleviate the damage of abiotic stress by improving plant tolerance. Therefore, jasmonic acid and amino acid conjugate (JA-Ile) represent stress hormones that improve crop resilience under environmental fluctuations. In addition, JA modulates the plant growth and developmental stages by regulating the crosstalk between JA and the main plant hormone groups, balancing plant development
