Functional Description ? help Back to Top
Source Description
TAIREncodes transcription factor involved in photomorphogenesis. Regulates gibberellin biosynthesis. Activated by AGAMOUS in a cal-1, ap1-1 background. Expressed at low levels in developing stamens. Increased levels of ATH1 severely delay flowering in the C24 accession. Most remarkably, ectopically expressed ATH1 hardly had an effect on flowering time in the Col-0 and Ler accessions. ATH1 physically interacts with STM, BP and KNAT6 and enhances the shoot apical meristem defect of some of these genes suggesting a role in SAM maintenance. Nuclear localization is dependent upon interaction with STM.
UniProtTranscription factor which may be involved in the signal transduction pathway downstream of the COP1 gene. Controls floral competency as a specific activator of FLC expression. Is responsive of the nuclear import of SHOOT MERISTEMLESS (STM). {ECO:0000269|PubMed:17908157}.

  1. ATH1 controls floral competency as a specific activator of FLOWERING LOCUS C (FLC) expression.
    [PMID: 17908157]
  2. Data show that ATH1 modulates growth at the interface between the stem, meristem, and organ primordia and contributes to the compressed vegetative habit of Arabidopsis thaliana.
    [PMID: 18757555]
  3. combined lesions in ATH1, PNY and PNF result in a full phenocopy of shoot apical meristem loss-of-function mutants.
    [PMID: 19175771]
  4. The data indicate that the ATH1-KNAT2 complex acts redundantly with KNAT6, both of which are negatively regulated by BP during pedicel development.
    [PMID: 22140242]
  5. BOP1/2 gain-of-function in stems promotes expression of the boundary gene KNOTTED1-LIKE FROM ARABIDOPSIS THALIANA6 (KNAT6) and ARABIDOPSIS THALIANA HOMEOBOX GENE1 (ATH1).
