Source Description
UniProtTranscription factor. Involved in epidermal cell fate specification. Negative regulator of trichome development, including endoreplication, by lateral inhibition involving intercellular interactions. Promotes the formation of hair developing cells (trichoblasts) in H position in root epidermis, probably by inhibiting non-hair cell (atrichoblasts) formation. {ECO:0000269|PubMed:10368181, ECO:0000269|PubMed:12356720}.

  1. The TRY protein has specific properties relevant for cluster formation and trichome density.

  2. Mutations in CPC or TRY delay flowering of cpl3 plants. A mutation in ETC1 did not further delay flowering but reduced plant size.
    [PMID: 23796522]
  3. AtMYC1 is negative regulator of TRY.
    [PMID: 23900543]
  4. Data show that TRANSPARENT TESTA GLABRA 2 (TTG2) is a specific activator of TRYPTICHON protein (TRY) by binding to W-boxes in a minimal promoter fragment of TRY.
    [PMID: 25304203]
  5. TRY, but not the related factor CPC, is responsible for the preferential SCM accumulation.
    [PMID: 25482776]
  6. In an intricate interplay between three partly redundant single R3 MYB proteins, CPC, ETC1, and TRY regulate several developmental, physiological and metabolic processes that are putatively located in different tissues.
