Phytohormone

Phytohormones, also known as plant endogenous hormones or plant natural hormones, are a class of organic compounds synthesized by specific tissues within plants that regulate plant physiological activities in minute quantities. These hormones modulate various physiological processes in plants by either promoting or inhibiting them, thereby controlling plant growth, development, environmental adaptation, and different stages of the plant lifecycle. The major classes of known phytohormones include six categories: auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Although these phytohormones are generally small, structurally simple molecules, their physiological effects are highly complex and diverse, influencing basic processes such as cell division, elongation, and differentiation. They also play a broad role in regulating important physiological phenomena such as germination, root formation, flowering, fruiting, sex determination, dormancy, and abscission^[1].

HY-N11420

Coronatine		98.40%
Coronatine is a plant growth regulator that mimicks the jasmonic acid-isoleucine conjugate (JA-Ile), targets the jasmonic acid receptor COI1, activates the jasmonic acid signaling pathway, thereby inhibiting salicylic acid (SA)-dependent defense responses. Coronatine antagonizes the stomatal closure, induces plant cell necrosis and chlorosis, interfers with plant hormone balance, thereby promoting pathogen infection.
