Research Progress on Factors and Molecular Mechanisms Regulating Plant Organ Abscission
摘要
Abstract
The organs abscission is a phenomenon in which parts of organs are separated from the body.It is an adap-tive 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 abscission zone formation,signal activation,cell separation,and is regulated by both internal(in vivo)physiological processes and external environmental factors including light,temperature,and humidity.In agricultural production,the abscission of plant organs directly affects crop yield.Understanding the regulatory mechanisms of plant organ abscission is greatly important for improving crop yield.In recent years,tremendous progress has been made in the study of organ abscission mechanisms.The studies showed that the mechanisms of organ abscission in plants are largely conservative between species,but also with sig-nificant variations.This review delved into the physiological and biochemical mechanisms of plant organ abscission,and summarized the effects of both the environmental factors and the hormones and enzymes in the process.The review provides a solid theoretical support and practical guidance for crop genetic breeding and agricultural production im-provement in connection with organ abscission.关键词
