The gaseous plant hormone ethylene modulates many internal processes and growth responses to environmental stimuli. Ethylene has long been recognized as a growth inhibitor, but evidence is accumulating that ethylene can also promote growth. Therefore, the concept of ethylene as a general growth inhibitor needs reconsideration: a close examination of recent literature can help to understand the two contrasting faces of growth control by ethylene. Here, we propose a hypothesis that integrates growth inhibition and growth stimulation into one biphasic ethylene response model. Focusing on photosynthesis and cell expansion, we highlight several mechanisms through which ethylene affects plant growth, thereby interacting with various other signal transduction routes.
气态植物激素乙烯调节许多内部过程以及对环境刺激的生长反应。长期以来，乙烯一直被认为是一种生长抑制剂，但越来越多的证据表明乙烯也能促进生长。因此，乙烯作为一种普遍的生长抑制剂这一概念需要重新审视：仔细研究近期文献有助于理解乙烯对生长控制的两种截然不同的作用。在此，我们提出一个假设，将生长抑制和生长刺激整合到一个双相乙烯反应模型中。以光合作用和细胞扩张为重点，我们强调了乙烯影响植物生长的几种机制，从而与各种其他信号转导途径相互作用。
