Abstract

As the last stage of leaf development, the initiation and progression of leaf senescence are tightly controlled by genetic programing and coordinated by both internal and external factors. Plant hormone is one of the important internal factors that affect leaf senescence. It is widely acknowledged that ethylene, abscisic acid, salicylic acid, jasmonic acid and brassinosteroids accelerate leaf senescence, while cytokinin and gibberellin delay leaf senescence. It was generally believed that auxin negatively regulates leaf senescence, but more and more recent studies show that auxin is a positive regulator of leaf senescence. This review aims to summarize the research progress in this field and to lay a foundation for a better understanding towards the function of auxin in leaf senescence regulation.
