Ethylene perception and responses: From prokaryotes to plants
Brad M. Binder
Ethylene was the first gaseous biological signaling molecule discovered. Plants biosynthesize ethylene in response to various cues to regulate growth, development, and responses to various stresses. However, its role in other organisms is less clear. Receptors for ethylene have been identified in plants and cyanobacteria. In land plants, responses to ethylene are mediated by a family of receptors. While these receptors have overlapping roles in the control of some traits, it is clear that they have also become sub-functionalized. Details about this sub-functionalization and cross-talk to other hormones will be presented. Additionally, the roles of ethylene receptors in a cyanobacterium and proteobacterium will be presented.
