ABA signalling: a messenger's FIERY fate.
There is considerable circumstantial evidence that the Ca(2+)-mobilizing second messenger IP(3) is involved in plant responses to the drought hormone abscisic acid. More direct evidence for this has now come from studies in which endogenous IP(3) levels have been manipulated in plants.
