Decoding the Intricate Metabolic and Biochemical Changes in Plant Senescence: a focus on chloroplasts and mitochondria.

Background: Plant senescence is a genetically controlled process that results in the programmed death of plant cells, organs, or the entire plant. This process is essential for nutrient recycling and supports the production of plant offspring. Environmental stresses such as drought and heat can hasten senescence, reducing photosynthetic efficiency and significantly affecting crop quality and yield.
