The plant hormone ethylene plays important roles in growth and development. Ethylene is perceived by a family of membrane-bound receptors that actively repress ethylene responses. When the receptors bind ethylene, their signaling is shut off, activating responses. REVERSION-TO-ETHYLENE SENSITIVITY (RTE1) encodes a novel membrane protein conserved in plants(More)
The plant ethylene receptor ETR1, which shows substantial sequence homology to typical bacterial histidine kinases, is involved in the coordination of several growth and development processes. Fluorescence polarization studies presented here demonstrate a specific interaction of ETR1 with the histidine-containing transfer protein AHP1, supporting the idea(More)
The ethylene receptor ethylene response 1 (ETR1) and the Arabidopsis histidine-containing phosphotransfer protein 1 (AHP1) form a tight complex in vitro. According to our current model ETR1 and AHP1 together with a response regulator form a phosphorelay system controlling the gene expression response to the plant hormone ethylene, similar to the(More)
