Ethylene signaling pathway

Ethylene signal transduction and the control of juvenile to adult phase transitions in the leaf. The pathway for ethylene signal transduction involves positive and negative regulators that culminate in transcriptional regulation by the EIN3-like family of transcription factors. Among the ethylene-responsive genes are some that encode additional transcription factors such as those of the ethylene response factor (ERF) and ethylene response DNA-binding factor (EDF) families. The pharmacological agents aminoethoxyvinylglycine (AVG) and silver can be used to inhibit ethylene responses through their ability to target ethylene biosynthesis or the receptors, respectively. One effect of ethylene is to stimulate the juvenile to adult phase transition of leaves. The transcription factor FUS3 negatively regulates the effects of ethylene on this developmental process.

乙烯信号传导与叶片从幼年期向成年期转变的调控机制。乙烯信号传导途径涉及正负调控因子，最终通过EIN3样转录因子家族的转录调控实现。在乙烯响应基因中，包括一些编码额外转录因子的基因，如乙烯响应因子（ERF）和乙烯响应DNA结合因子（EDF）家族的基因。通过针对乙烯生物合成或受体的作用，药物制剂氨基乙氧基乙烯基甘氨酸（AVG）和银可以用于抑制乙烯反应。乙烯的一种效应是刺激叶片从幼年期向成年期的转变。转录因子FUS3对乙烯在此发育过程中的影响具有负向调控作用。
