Abstract: Ethylene,a key endogenous phytohormone,is involved in multiple plants’ life activities,and plays an important role in regulating floral development and senescence. In flowers,researchers can affect the production of ethylene by regulating related genes of ethylene biosynthesis and its signal transduction,and further regulate the floral development process and aging process. Currently,studies on prolonging florescence by regulating endogenous ethylene are mainly applied to ornamental flowers,but few to medicinal or other flowers. This paper summarizes the models of ethylene biosynthesis and ethylene signal transduction pathway,interaction patterns of its related genes,and researches of cloning and regulating related genes involved in ethylene response mediating floral development and senescence in recent years. It is expected to apply studies which prolong plants’ florescence by regulating related genes of ethylene biosynthesis and signal transduction pathway to ornamental,medicinal and other flowers with short flowering period,and provide references for cultivating fine breeding of ornamental and medicinal flowers by regulating endogenous ethylene generation and transduction at genetic level.

Key words: ethylene biosynthesis, ethylene signal transduction, flower senescence, gene regulation
