HY5 regulates anthocyanin biosynthesis by inducing the transcriptional activation of the MYB75/PAP1 transcription factor in Arabidopsis
Abstract
Several positive transcription factors regulate Arabidopsis anthocyanin biosynthesis. HY5, a component of light‐signaling pathways, and PAP1, an R2R3‐MYB transcription factor, share common regulatory targets on anthocyanin biosynthesis genes. The epistatic interactions between the two transcription factors are currently unknown. To address this problem, we analyzed crosses between hy5 and pap1 mutants (hy5pap1) or pap1D overexpressors (hy5pap1D), performed chromatin immunoprecipitation‐qPCR, and determined the PAP1 promoter region through deletion analysis. The results show that HY5 regulates PAP1 expression via direct binding to G‐ and ACE‐boxes in the promoter region, which suggests bifurcate regulation of anthocyanin biosynthesis by HY5 via transcriptional activation of PAP1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
