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… CONTINUE READING
