Delta subclass HD-Zip proteins and a B-3 AP2/ERF transcription factor interact with promoter elements required for expression of the Arabidopsis cytochrome c oxidase 5b-1 gene.

Abstract excerpt

We have identified transcription factors that interact with a promoter region involved in expression of the Arabidopsis thaliana COX5b-1 gene, which encodes an isoform of the cytochrome c oxidase zinc binding subunit. Elements with the core sequence ATCATT, involved in induction by sugars, are recognized both in vitro and in one-hybrid assays in yeast by HD-Zip proteins from the delta subclass and, though less...
