Research Progress on Plant Leaf Abscission
摘要
Abstract
Plant abscission is an active and highly regulated physiological process that occurs either as part of normal development or in response to environmental stimuli.It serves as an adaptive mechanism that enables plants to cope with environmental changes.Leaf abscission is closely related to the formation and degradation of the abscission zone and is tightly regulated by phytohormone signaling.These processes are controlled by complex genetic regulatory networks.This review synthesizes recent advances in understanding the mechanisms of leaf abscission from cytological,histological,physiological,biochemical,and molecular perspectives.By integrating key research findings,it provides a comprehensive overview of the regulatory framework underlying plant leaf abscission.Furthermore,it offers theoretical insights and methodological references to guide future studies on leaf abscission in forage grasses.关键词
