Biochemical Pathway and Perception The biosynthesis of ethylene begins with the amino acid methionine, which is converted through a series of enzymatic steps involving SAM synthetase and ACC synthase to produce 1-aminocyclopropane-1-carboxylic acid (ACC). During pathogen invasion, ethylene often works synergistically with jasmonic acid to activate defense genes.
Ethylene Function Receptor Signaling Pathway and Its Role in Plant Stress Response
Cross-talk between ethylene and brassinosteroids or gibberellins fine-tunes growth adjustments, ensuring that developmental decisions balance resource allocation and environmental cues. Often referred to as the aging hormone, ethylene is unique among plant hormones because of its volatility and its ability to act as a signaling molecule at extremely low concentrations.
Response to Biotic and Abiotic Stress Under stress conditions such as drought, flooding, or pathogen attack, ethylene function becomes a critical coordinator of defense and adaptation. In some species, it can trigger the transition from vegetative to reproductive growth, ensuring that flowering coincides with favorable environmental conditions.

ACC is then oxidized by ACC oxidase to yield ethylene, a reaction that requires oxygen and iron. Applications in Agriculture and Horticulture Manipulation of ethylene function is a cornerstone of modern horticultural practice.
