Abscisic acid (ABA) signalling pathways have been widely characterized in plants; whereas the function of ABA in animals is less well understood. However, recent advances show ABA production by a wide range of lower animals and higher mammals. This allows a new evaluation of ABA signalling pathways in different organisms in response to a common environmental stress such as UV-B. Here we propose that the induction of common signalling components, such as ABA, nitric oxide (NO) and Ca2+ in plant and animal cells in response to high doses of UV-B, suggests that the evolution of a general mechanism activated by UV-B is conserved in divergent multicellular organisms challenged by a changing common environment.
