Source Description
UniProtTranscription factor that promotes photomorphogenesis in the light and positively regulates fruit pigmentation and fruit nutritional quality. Probably acts downstream of the light receptor network and directly affects transcription of light-induced genes. {ECO:0000269|PubMed:15178762}.
Function -- GeneRIF ? help Back to Top
  1. Through binding to the promoter of ABI5, HY5 triggers enhanced photoprotection through induction of an apoplastic H2O2 burst that influences antioxidant status, cyclic electron flux(CEF), and nonphotochemical quenching(NPQ). This enhanced photoprotection allows shade leaves to avoid photoinhibition. [HY5]

  2. mediates CRY1a-induced anthocyanin biosynthesis
    [PMID: 29566255]
  3. Long hypocotyl 5 protein inhibits tomato growth and induces cold tolerance by integrating both light and temperature signaling.
