Triple hab1-1abi1-2abi2-2 (triple abi2-2) and hab1-1abi1-2pp2ca-1 (triple pp2ca-1) mutants show partial constitutive up-regulation and down-regulation of ABA-responsive genes in the absence of exogenous ABA. A, Venn diagrams. Number of ABA-responsive genes that show up-regulation and down-regulation in triple mutants in the absence of exogenous ABA. B, Expression of RAB18 and RD29B in triple mutants with respect to wild type. qRT-PCR analyses were made in triplicate on RNA samples of 2-week-old seedlings that were either mock or 10 μm ABA-treated for 3 h. Numbers indicate the expression level of the RAB18 and RD29B genes under mock (−) or ABA treatment (+) in each mutant genotype with respect to the wild type (value 1). C, Comparison of GO categories for ABA-responsive genes in ABA-treated wild type versus triple mutants in the absence of exogenous ABA.
