摘      要：Two-component signal transduction is commonly used as a stimulus-response coupling mechanism to allow organisms such as eubacteria, archea, and a few eukaryotes to sense and respond to changes in many different environmental conditions （Stock et al., 2000）. Typically, the histidine protein kinase senses extracellular stimuli by autophosphorylation and transfers a phosphoryl group to the response regu- lator, resulting in activation of downstream proteins that elicit a specific response. In Arabidopsis plants, a multi-step two-component system is well established as a key element of plant hormone cytokinin signaling （To and Kieber, 2008）.
