title: Convergence of the abscisic acid, CO2, and extracellular calcium signal transduction pathways in stomatal guard cells.
abstract: We show that guard cells from Arabidopsis thaliana plants carrying the abscisic acid-insensitive mutations abi1 and abi2 fail to respond to CO2 and extracellular calcium. This demonstrates that the signal transduction pathways for all three stimuli converge on, or close to, the ABI1 and ABI2 gene products.
