Ethylene is a gaseous signal sensed by plants and bacteria. The characterization of an ethylene signalling pathway affecting phototaxis in cyanobacteria implies that biotechnologically relevant ethylene synthesis may induce specific regulatory processes in the cell. Here, we provide data that ethylene mainly deactivates transcription from a promoter, which is under the control of a UV-A responsive two-component system.
