Arabidopsis AtbHLH112 protein binds to the G-box and a novel motif GCG-box to regulate gene expression in response to abiotic stress

ABSTRACT: Plant basic helix-loop-helix (bHLH) proteins play essential roles in physiological and developmental processes and are also involved in abiotic stresses. However, their exact roles in abiotic stress are still not fully understood, and most of them have not been functionally characterised. In the present study, we characterised the functional role of AtbHLH112 in response to abiotic stress. A WRKY gene, AtWRKY66, can regulate the expression of the AtbHLH112 via binding to W-box motifs present in its promoter. AtbHLH112 is a nuclear-localised protein, and its nuclear localisation is increased upon exposure to NaCl, mannitol and ABA. In addition to binding to the G-box motif, AtbHLH112 is found to bind to a novel motif M-bM-^@M-^\GGGCCGGTCM-bM-^@M-^] (named the GCG-box) to regulate gene expre
