Linked Claims

Claim 1binding specificitysupports1998Source 1DOIPubMed

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
Claim 3mechanistic modelsupports1998Source 1DOIPubMed

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.
Claim 4mutant phenotypesupports1998Source 1DOIPubMed

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.
Claim 5regulatory rolesupports1998Source 1DOIPubMed

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
