|a Flower senescence is a fundamental aspect of the developmental trajectory in flowers, occurring after the differentiation of tissues and maturation of petals, and preceding the growth and development of seeds. It is accompanied by various alterations at the cytological, physiological, and molecular levels, similar to other forms of programmed cell death (PCD). It involves an intricate interplay of various plant growth regulators, with ethylene being the key orchestrator in ethylene-dependent petal senescence. Petal senescence mediated by ethylene is marked by various changes such as petal wilting, amplified oxidative stress, degradation of proteins and nucleic acids, and autophagy. Ethylene crosstalks with other growth regulators and triggers genetic and/or epigenetic reprogramming of genes during senescence in flowers. While our understanding of the mechanism and regulation of petal senescence in ethylene-sensitive species has advanced, significant knowledge gaps still exist, which demand critical reappraisal of the available literature on the topic. A deeper understanding of the various mechanisms and regulatory pathways involved in ethylene-dependent senescence has the capacity to facilitate a more precise regulation of the timing and site of senescence, thus leading to optimized crop yields, enhanced product quality, and extended longevity
