Research Progress on Factors and Molecular Mechanisms Regulating Plant Organ Abscission

doi:10.11983/CBB24133

Abstract

Abstract: The organs abscission is a phenomenon in which parts of organs are separated from the body. It is an adaptive strategy evolved by plants in the process of growth and response to environmental changes, which ensures the normal growth and adaptation of plants to the environment. This process involves the formation of abscission zones, activation of specific signals, cell separation, and is significantly regulated by its own physiological processes and external environmental factors such as light, temperature, and humidity. In agricultural production, the abscission of plant organs directly affects crop yield. Studying the regulatory mechanism of plant organ abscission is crucial for improving crop yield. In recent years, significant progress has been made in the study of organ abscission mechanisms. The results show that the mechanism of organ abscission in plants is conservative, but there are also significant variation among different species.This review will delve into the physiological and biochemical mechanisms of plant organ abscission, analyze the specific effects of different environmental factors, and the specific roles played by hormones and enzymes in this process. The aim is to provide solid theoretical support and practical guidance for crop genetic breeding and agricultural production.

Key words: organ abscission, abscission zone, molecular mechanism, enzyme, phytohormone
