Abstract: Auxin has long been identified to play a critical role in regulating various activities of plant growth and development. However, systematic and in-depth understanding of these regulations is still lacking. Recently, the verification of the nucleic auxin signaling pathway has thrown light on research in this field. The hormone ethylene is involved in fruit ripening and the stress response of plants; its signaling pathway has been partially elucidated. Increasing data show that the effects of ethylene on plants are largely connected to the participation of auxin. In this review, we summarize the research advances in auxin and ethylene signaling and discuss the role of auxin in the triple response of ethylene. Difficulties in unraveling their relationship and possible ways of resolving them are also proposed.
