Plants, like other sessile organisms, need to sense many different signals, and in response to them, modify their developmental programs to be able to survive in a highly changing environment. The multistep phosphorelay (MSP) in plants is a good candidate for a response mechanism that integrates multiple signal types both environmental and intrinsic in origin. Recently, ethylene was shown to control MSP activity via the histidine kinase (HK) activity of ETHYLENE RESPONSE 1 (ETR1)^1,2, but the underlying molecular mechanism still remains unclear.

AHK5 在拟南芥中介导 ETR1 启动的多步磷酸传递

植物与其他固着生物一样，需要感知许多不同的信号，并根据这些信号修改发育程序，以便能够在高度变化的环境中生存。植物中的多步磷继电器 (MSP) 是一种很好的响应机制候选者，该机制整合了多种来源的环境和内在信号类型。最近，乙烯显示出通过 ETHYLENE RESPONSE 1 (ETR1) ^1,2的组氨酸激酶 (HK) 活性控制 MSP 活性，但潜在的分子机制仍不清楚。
