A hypothetical model for the signalling role of JA, SA, ABA, and H2O2 in the regulation of stomatal aperture in abi1-1 during water deficit, heat stress, and a combination of water deficit and heat stress. Dotted lines indicate hypothetical interactions. Solid lines and arrows indicate positive and negative regulation based on published literature, respectively. Abbreviations: ABA, abscisic acid; JA, jasmonic acid; NO, nitric oxide; SA, salicylic acid; SLAC1, SLOW ANION CHANNEL-ASSOCIATED 1.
