Determinants in the sequence specific binding of two plant transcription factors, CBF1 and NtERF2, to the DRE and GCC motifs.

Abstract excerpt

Arabidopsis ERF proteins such as DREB1, DREB2, and CBF1 bind to the dehydration-responsive element (DRE), which has the sequence TACCGACAT. Mutation analyses reveal that a central 5 bp CCGAC core of the DRE is the minimal sequence motif (designated as the DRE motif in this paper), to which the ERF domain fragment of CBF1 (CBF1-F) binds specifically with a binding K(d) at the nanomolar level. In contrast, the ERF...
