• [Display omitted] •Abiotic stresses concurrently trigger ABA and Ca2+ signals.•These ABA and Ca2+ signals convergently modulate common targets.•ABA and Ca2+ signaling components form an intricate signaling network.•Consequences of ABA and Ca2+ signaling result from complex signal integration.•PP2C type phosphatases are master regulators of ABA and Ca2+ signaling. Abiotic stresses simultaneously trigger an increase in the level of the plant hormone abscisic acid (ABA) and in the concentration of cytosolic calcium. Subsequent signaling cascades convey stomata regulation and transcriptional responses. Increasing evidence points to direct interrelations of both signaling systems on multiple levels of information processing. In this context, protein phosphatases 2Cs of the clade A appear to function as master regulators of both ABA and calcium signaling. In this review, we focus on informative examples for convergence of ABA and calcium signaling on common target proteins and discuss emerging concepts, consequences and open questions about the integration of calcium and ABA signaling.
