EIN3/EIL1 transcription factors are the key regulators of ethylene signaling that sustain a variety of plant responses to ethylene. Since ethylene regulates multiple aspects of plant development and stress responses, its signaling outcome needs proper modulation depending on the spatiotemporal and environmental conditions. In this review, we summarize recent advances on the molecular mechanisms that underlie EIN3/EIL1-directed ethylene signaling in Arabidopsis. We focus on the role of EIN3/EIL1 in tuning transcriptional regulation of ethylene response in time and space. Besides, we consider the role of EIN3/EIL1-independent regulation of ethylene signaling.
EIN3/EIL1转录因子是乙烯信号传导的关键调节因子，维持植物对乙烯的多种反应。由于乙烯调节植物发育和应激反应的多个方面，其信号传导结果需要根据时空和环境条件进行适当调节。在本综述中，我们总结了拟南芥中EIN3/EIL1介导的乙烯信号传导分子机制的最新进展。我们重点关注EIN3/EIL1在时空上调节乙烯反应转录调控中的作用。此外，我们还考虑了乙烯信号传导中不依赖EIN3/EIL1的调节作用。
