aging

2 articles

Aging in plants refers to the genetically regulated processes of cellular senescence and developmental decline that occur over a plant's lifespan, from leaf yellowing to whole-plant deterioration. Unlike animals, many perennial plants exhibit remarkable longevity and can even display negligible senescence, making them valuable models for studying the molecular mechanisms that govern biological aging. Understanding plant aging has direct implications for crop yield, stress tolerance, and the development of interventions that could extend productive lifespan in agricultural species.
