leaf se·nes·cence
Definitions related to leaf senescence:
-
The last stage of leaf development in which the leaf cells undergo an ordered process of disassembly of organelles and changes in gene expression and metabolism. During leaf senescence the chloroplasts breakdown and metabolism switches from photosynthesis to converting growth-phase accumulated materials into exportable nutrients for seed development, in annual plants; or to the stems and roots to be stored for the next season, in perennials.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
The process that occurs in a leaf near the end of its active life that is associated with the dismantling of cell components and membranes, loss of functional chloroplasts, and an overall decline in metabolism.Gene Ontology DictionaryGene Ontology Consortium, 2021
