Leaf senescence represents the final stage of plant development, involving nutrient redistribution and cellular degradation. Ethylene, a gaseous hormone, plays a pivotal role in regulating this process. Despite extensive research, gaps persist in understanding ethylene's contribution to leaf senescence comprehensively. This review synthesizes existing literature to elucidate ethylene's signalling cascade, interaction with other hormones, and response to environmental stress. Key findings highlight the nuanced relationship between ethylene, leaf age, and environmental factors, emphasising the need for further investigation to optimize plant health and agricultural productivity.
