The hormone abscisic acid (ABA) mediates plant development and adaptation to environmental stresses ABA-dependent transcription factors are central regulators of ABA signaling Here we report on the identification of the ABA-induced transcriptional repressor Arabidopsis zinc-finger protein 2 (AZF2) as ABA signaling component We isolated azf2-1 mutants lacking AZF2 full-length transcripts that were hypersensitive to ABA during seed germination In line with a function of AZF2 in seed germination and seedling development AZF2-promoter activi
