Applications in Agriculture and Horticulture Manipulation of ethylene function is a cornerstone of modern horticultural practice. From seed germination to fruit ripening and response to stress, this simple two-carbon molecule coordinates complex developmental programs that determine crop yield and quality.
Ethylene Function in Abiotic Stress Tolerance and Adaptation
Plants perceive ethylene through a family of receptors located on the endoplasmic reticulum membrane. In the nursery industry, it is employed to induce flowering in species like poinsettia and kalanchoe.
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. ACC is then oxidized by ACC oxidase to yield ethylene, a reaction that requires oxygen and iron.
Ethylene Function in Abiotic Stress Tolerance and Crop Improvement
Understanding this process has allowed the development of controlled atmosphere storage and the use of ethylene inhibitors like 1-MCP, which extend shelf life and reduce postharvest losses globally. Breeding programs increasingly focus on modifying ethylene sensitivity to improve lodging resistance in cereals and enhance drought tolerance in legumes, demonstrating the tangible benefits of understanding this pathway.
