植物激素乙烯调节生长和发育以及应激反应。本文综述了最近的发现，支持乙烯信号转导模型，涉及重叠和非重叠的乙烯受体家族成员的作用。乙烯受体在调节植物生长，病原菌反应和发展的作用进行了讨论。提出了受体可以共同和独立调节下游反应的机制。植物激素乙烯调节生长和发育以及对生物和非生物胁迫的反应。在过去的几十年中，参与乙烯信号转导的关键元件已被确定通过遗传方法，这些元件定义了一个途径，从最初的乙烯在内质网的感知延伸到核内的转录调控的变化。在这里，我们提出了我们目前的乙烯信号转导的理解，侧重于最近的发展，支持一个模型与重叠和非重叠的作用，乙烯受体家族的成员。我们认为，证据支持这种模式的受体家族内的亚功能化，然后讨论这种亚功能化可能发生的机制。为此，我们考虑受体相互作用在调节其信号输出的重要性，以及这种相互作用如何在受体家族中变化。此外，我们认为有证据表明，乙烯信号输出的受体涉及磷酸化依赖和磷酸化独立的机制。我们的结论与目前的乙烯信号转导的整体背景下放置的乙烯受体的信号模型。
The plant hormone ethylene regulates growth and development as well as stress responses. This review focuses on recent discoveries that support a model for ethylene signal transduction that involves overlapping and non-overlapping roles for members of the ethylene receptor family. The roles of ethylene receptors in regulating plant growth, pathogen responses, and development are discussed. Mechanisms are proposed by which receptors can modulate downstream responses together and independently. The plant hormone ethylene regulates growth and development as well as responses to biotic and abiotic stresses. Over the last few decades, key elements involved in ethylene signal transduction have been identified through genetic approaches, these elements defining a pathway that extends from initial ethylene perception at the endoplasmic reticulum to changes in transcriptional regulation within the nucleus. Here, we present our current understanding of ethylene signal transduction, focusing on recent developments that support a model with overlapping and non-overlapping roles for members of the ethylene receptor family. We consider the evidence supporting this model for sub-functionalization within the receptor family, and then discuss mechanisms by which such a sub-functionalization may occur. To this end, we consider the importance of receptor interactions in modulating their signal output and how such interactions vary in the receptor family. In addition, we consider evidence indicating that ethylene signal output by the receptors involves both phosphorylation-dependent and phosphorylation-independent mechanisms. We conclude with a current model for signalling by the ethylene receptors placed within the overall context of ethylene signal transduction.
