Gaseous signal molecules affect a range of physiological and developmental processes in plants and animals. Investigating the activities of the ethylene receptor in plants, Rodríguez et al. (p. 996) found that a copper ion serves as a critical cofactor. A similar protein in cyanobacteria, organisms thought to be related to the original precursors of plant chloroplasts, also binds ethylene. Comparison of the two proteins suggests a structure for the receptors.
