Cytokinin-auxin crosstalk in cell type specification.
Köln, Germany. In Trends Plant Sci, May 2015
Similarly to auxin, local cytokinin synthesis and response gradients are instructive, and the roles of ARABIDOPSIS RESPONSE REGULATOR 7/15 (ARR7/15) and the negative cytokinin response regulator ARABIDOPSIS HISTIDINE PHOSPHOTRANSFER PROTEIN 6, as well as auxin signalling via MONOPTEROS/BODENLOS, are functionally conserved across different developmental processes.
Auxin triggers a genetic switch.
Tübingen, Germany. In Nat Cell Biol, 2011
Here, we demonstrate by experimental and computational analyses that the Arabidopsis ARF protein MONOPTEROS (MP) controls its own expression and the expression of its AUX/IAA inhibitor BODENLOS (BDL), with auxin acting as a threshold-specific trigger by promoting the degradation of the inhibitor.
Transcriptional regulation of vascular cell fates.
Tokyo, Japan. In Curr Opin Plant Biol, 2010
The positive feedback loop typically shown in auxin-flow-MONOPTEROS-(HD-ZIP IIIs)-PIN1-auxin-flow in procambial precursor cell determination and VND7-ASL/LBD-VND7 in xylem vessel cell determination, may be a crucial mechanism that determines vascular cell fates, which occurs in stages.
Hormonal control of the shoot stem-cell niche.
Heidelberg, Germany. In Nature, 2010
Whereas ARR7 and ARR15 expression in the shoot apical meristem (SAM) is induced by cytokinin, auxin has a negative effect, which is, at least in part, mediated by the AUXIN RESPONSE FACTOR5/MONOPTEROS (MP) transcription factor.
