Transcription Factor Veracity: Is GBF3 Responsible for ABA-Regulated Expression of Arabidopsis Adh?

Assignment of particular transcription factors to specific roles in
promoter elements can be problematic, especially in systems such as the
G-box, where multiple factors of overlapping specificity exist. In the
Arabidopsis alcohol dehydrogenase (Adh) promoter, the G-box regulates
expression in response to cold and dehydration, presumably through the
action of abscisic acid (ABA), and is bound by a nuclear protein complex in
vivo during expression in cell cultures. In this report, we test the
conventional wisdom of biochemical approaches used to identify DNA binding
proteins and assess their specific interactions by using the G-box and a
nearby half G-box element of the Arabidopsis Adh promoter as a model
system. Typical in vitro assays demonstrated specific interaction of G-box
factor 3 (GBF3) with both the G-box and the half G-box element. Dimethyl
sulfate footprint analysis confirmed that the in vitro binding signature of
GBF3 essentially matches the footprint signature detected in vivo at the
G-box. Because RNA gel blot data indicated that GBF3 is itself induced by
ABA, we might have concluded that GBF3 is indeed the GBF responsible in
cell cultures for binding to the Adh G-box and is therefore responsible for
ABA-regulated expression of Adh. Potential limitations of this conclusion
are exposed by the fact that other GBFs bind the G-box with the same
signature as GBF3, and subtle differences between in vivo and in vitro
footprint signatures indicate that factors other than or in addition to
GBF3 interact with the half G-box element.
