The simple gas ethylene profoundly influences plants at nearly every stage of growth and development. In the past ten years, the use of a genetic approach, based on the triple response phenotype, has been a powerful tool for investigating the molecular events that underlie these effects. Several fundamental elements of the pathway have been described: a receptor with homology to bacterial two-component histidine kinases (ETR1), elements of a MAP kinase cascade (CTR1) and a putative transcription factor (EIN3). Taken together, these elements can be assembled into a simple, linear model for ethylene signalling that accounts for most of the well-characterized ethylene mediated responses.
简单气体乙烯几乎在植物生长和发育的每个阶段都对其产生深刻影响。在过去十年中,基于三重反应表型的遗传学方法一直是研究这些效应背后分子事件的有力工具。该信号通路的几个基本元件已被描述:与细菌双组分组氨酸激酶具有同源性的受体(ETR1)、丝裂原活化蛋白激酶级联反应的元件(CTR1)和一个假定的转录因子(EIN3)。这些元件共同构成了一个简单的乙烯信号线性模型,该模型解释了大多数已充分表征的乙烯介导的反应。
