HY5 binds specifically to G-box DNA sequences and not to other examined light-responsive elements.
Quoted textsource-backed
In vitro DNA binding studies suggested that HY5 can bind specifically to the G-box DNA sequences but not to any of the other LREs present in the light-responsive promoters examined.
Phytochrome-mediated red light- and far-red light-reversible low-fluence induction of G-box-containing promoters is diminished in hy5 plants.
Quoted textsource-backed
the characteristic phytochrome-mediated red light- and far-red light-reversible low-fluence induction of the G-box-containing promoters was diminished specifically in hy5 plants
HY5 may directly interact with the G-box in promoters of light-inducible genes to mediate light-controlled transcriptional activity.
Quoted textsource-backed
These results suggest that HY5 may interact directly with the G-box in the promoters of light-inducible genes to mediate light-controlled transcriptional activity.
High-irradiance light activation of G-box-containing synthetic promoters and the RBCS-1A promoter is significantly compromised in the hy5 mutant.
Quoted textsource-backed
High-irradiance light activation of two synthetic promoters containing either the consensus G-box alone or the G-box combined with the GATA motif (another LRE) and the native Arabidopsis ribulose bisphosphate carboxylase small subunit gene RBCS-1A promoter, which has an essential copy of the G-box, was significantly compromised in the hy5 mutant.
HY5 is involved in light regulation of transcriptional activity of promoters containing the G-box.
Quoted textsource-backed
HY5 is constitutively nuclear localized and is involved in light regulation of transcriptional activity of the promoters containing the G-box
