Proposed model of DREB1A-regulated AtTPPF drought-response network. Under well-watered conditions, DREB1A is in “OFF” position. Under drought stress, expression of DREB1A is induced to bind to DRE/CRT motif in promoter of AtTPPF, thereby activating AtTPPF transcription. Increased expression of TPPF most likely affects T6P signal, which may be a causal factor in the increase of soluble sugars, which function as osmotic protectors and scavengers of reactive oxygen species in the shoot apical meristem. This helps young leaves survive under long-term drought conditions
