Overview
Ethylene (ETH, H2C=CH2), a gaseous phytohormone, is the first gaseous molecule found to function as a hormone. Since ethylene was initially known to stimulate adventitious root formation, there has been a great interest in exploring ethylene. Studies have found that ETH plays an important role in modulating plant growth and development throughout the plant life cycle, including seed germination, flower senescence, and fruit ripening and abscission. ETH is also involved in defense against pathogens or elicitor attacks, and responses to abiotic stresses like chemical exposure, hypoxia, wounding, freezing, chilling, nutrient availability, and flooding. Moreover, the ETH concentration may vary according to the plant species, developmental stage of the plant, and organ types such as flower, root, and leaf. It is very important to monitor and control ethylene emission in plants to accelerate plant growth and fruit freshness. Thus, there is a growing demand for simple, affordable, and accurate ETH analysis methods for measuring ETH concentrations.
