The gaseous plant hormone ethylene plays crucial roles in many aspects of plant growth, development and stress responses. Ethylene signaling is initiated upon its binding to the ethylene receptors. Since the cloning of the first ethylene receptor ETR1 from Arabidopsis , efforts have been made in elucidation of ethylene receptor organization, signaling, and receptor-interacting proteins in higher plants. However, the update information about the ethylene receptors, receptor interacting proteins and their regulatory functions and molecular mechanisms has not been well scrutinized and discussed. Critical questions regarding the confusing or contradictory responses and phenotypes have been barely answered. This article gave an overview of the current progress in the identification, regulatory functions and possible molecular mechanisms of the ethylene receptors and receptor-interacting proteins in ethylene signaling and responses. The novel findings of the crosstalk between ethylene signaling and the other plant hormones were integrated into the review article. Questions and future research directions about the key components in the regulation of ethylene signaling were also proposed and emphasized. The update message may greatly facilitate comprehensive understanding of the ethylene signaling and molecular regulations in higher plants.

高等植物乙烯受体及受体相关蛋白的调控功能及分子机制

气态植物激素乙烯在植物生长、发育和胁迫反应的许多方面起着至关重要的作用。乙烯信号在其与乙烯受体结合后启动。自从从拟南芥中克隆出第一个乙烯受体 ETR1 以来，已经在阐明高等植物中乙烯受体的组织、信号传导和受体相互作用蛋白方面做出了努力。然而，关于乙烯受体、受体相互作用蛋白及其调节功能和分子机制的更新信息尚未得到很好的审查和讨论。关于令人困惑或矛盾的反应和表型的关键问题几乎没有得到回答。本文概述了鉴定的当前进展，乙烯受体和受体相互作用蛋白在乙烯信号和反应中的调节功能和可能的分子机制。乙烯信号与其他植物激素之间串扰的新发现被整合到评论文章中。还提出并强调了乙烯信号调控关键成分的问题和未来研究方向。更新信息可能会极大地促进对高等植物乙烯信号和分子调控的全面了解。还提出并强调了乙烯信号调控关键成分的问题和未来研究方向。更新信息可能会极大地促进对高等植物乙烯信号和分子调控的全面了解。还提出并强调了乙烯信号调控关键成分的问题和未来研究方向。更新信息可能会极大地促进对高等植物乙烯信号和分子调控的全面了解。
