May play a role in the regulation of shoot development, downstream of photomorphogenic activation (Probable). Acts as negative regulator of abscisic acid (ABA) signaling during germination and early seedling development (PubMed:24808098). Highly expressed in the shoot apex, including the apical meristem, developing leaves and developing vascular system. Induced by white light in dark-grown seedlings. Seeds over-expressing ZFP1 are insensitive to inhibition of germination by abscisic acid (ABA).
