...Rumi Tominaga-Wada; Takuji Wada The CAPRICE ( CPC ) gene encodes a R3-type MYB transcription factor that promotes differentiation of root hair cells in Arabidopsis thaliana . Here, we have compared the functions of five CPC -homologous genes for epidermal cell differentiation using CPC promoter...

... morphogenesis and differentiation into proacini by suppressing Kit expression through the upregulation of the transcription factor MYB, and concomitantly increasing the expression of distal progenitor markers. In addition, WNT signaling at the early stage of SMG development promoted end bud cell proliferation...

... of the usual monocilium. Here we report that the transcription factor MYB, which promotes S phase and drives cycling of a variety of progenitor cells, is expressed in postmitotic epithelial cells of the mouse airways and ependyma destined to become MCCs. MYB is expressed early in multiciliogenesis...

... of PU.1 to inhibit important T-cell transcription factor genes such as Myb, Tcf7 and Gata3 in the absence of Notch signaling. We show that maintenance of Gata3 protein levels by Myb and Notch signaling is linked to the ability to retain T-cell identity in response to PU.1. Non-tissue culture treated...

... signals. Communication between the meristem and lateral organs is crucial for meristem maintenance and organ patterning, and organ boundaries are thought to be important for mediating this communication. Arabidopsis thaliana LATERAL ORGAN FUSION1 ( LOF1 ) encodes a MYB-domain transcription factor...

... in the Arabidopsis epidermis is regulated by a lateral inhibition mechanism that relies on interactions between transcription factors. However, it is unclear how temporal- or organ-specific differences in epidermal patterning are achieved. Here we identify TRICHOMELESS1 (TCL1) as a new and major single-repeat MYB...

Katzen Drosophila melanogaster possesses a single gene, Dm myb , that is closely related to the vertebrate family of Myb genes, which encode transcription factors that are involved in regulatory decisions affecting cell proliferation...

...Siau-Min Fung; Gary Ramsay; Alisa L. Katzen We have previously established that the single myb gene in Drosophila melanogaster , Dm myb , which is related to the proto-oncogene Myb , is required for the G 2 /M transition of the cell cycle and for suppression of endoreduplication in pupal wing cells...

This negative regulatory region contains a consensus binding site for the myb family of transcription factors. In vitro DNA-binding...
