Source Description
UniprotDEVELOPMENTAL STAGE: Specifically expressed in the hypophysis of the majority of early globular embryos, approximately one round of cell division after the 16-cell stage, but never at the 16-cell stage itself. After the division of the hypophysis, it is detected in the upper lens-shaped cell that gives rise to the QC, but not in the lower daughter cell that gives rise to the central root cap. Subsequently, in heart stage and bent cotyledon stage embryos, it is detected in the four cells of the QC, which are the direct descendants of the lens-shaped cell. Also expressed in patches of cells that appeared associated with the vascular primordium of the cotyledons. This expression is strongest in late heart stage embryos and then gradually decreases. {ECO:0000269|PubMed:14711878}.
UniprotTISSUE SPECIFICITY: Specifically expressed in the central cells of a quiescent center (QC) of the root. {ECO:0000269|PubMed:14711878}.

Function -- GeneRIF ? help Back to Top
  1. Importantly, both WOX5 and WUS maintain stem cells in either a root or shoot context.
    [PMID: 17429400]
  2. The MKO1 gene plays an important role in the maintenance of the root apical meristem proliferative capacity and indeterminate root growth, which apparently acts independently of the SCR/SHR and WOX5 regulatory pathways.
    [PMID: 21744091]
  3. Studies indicate that the shoot and root meristems are promoted by WUSCHEL (WUS) and WOX5.
    [PMID: 22076631]
  4. WOX5-IAA17 feedback circuit is essential for the maintenance of auxin gradient in the root tip.
    [PMID: 23939433]
  5. WOX5 restrains cell division in the cells of the quiescent center, thereby establishing quiescence. In contrast, WOX5 and CYCD3;3/CYCD1;1 both promote cell proliferation in the nascent columella.
    [PMID: 25127220]
  6. ROW1 is essential for quiescent centre maintenance and for stem cell niche development through the repression of WOX5 in the proximal meristem.
    [PMID: 25631790]
  7. Results show that ACR4 phosphorylates WOX5 through four phosphorylation sites within the WOX5 protein sequence.
    [PMID: 25756623]
  8. WOX5 signals from the quiescent centre to promote columella stem cell (CSC) fate, while CLE40 is secreted from the differentiated columella cells to promote differentiation.
