Journal ArticleDOI
Root gravitropism requires lateral root cap and epidermal cells for transport and response to a mobile auxin signal
Ranjan Swarup,Eric M. Kramer,Paula Perry,Kirsten Knox,H. M. Ottoline Leyser,Jim Haseloff,Gerrit T.S. Beemster,Rishikesh P. Bhalerao,Malcolm J. Bennett +8 more
TL;DR: It is concluded that gravitropic curvature in Arabidopsis roots is primarily driven by the differential expansion of epidermal cells in response to an influx-carrier-dependent auxin gradient.
Journal ArticleDOI
Auxin transport through non-hair cells sustains root-hair development.
Angharad R. Jones,Eric M. Kramer,Eric M. Kramer,Kirsten Knox,Kirsten Knox,Ranjan Swarup,Malcolm J. Bennett,Colin M. Lazarus,H. M. Ottoline Leyser,Claire S. Grierson +9 more
TL;DR: Three-dimensional modelling of auxin flow in the root tip suggests that AUX1-dependent transport through non-hair cells maintains an auxin supply to developing hair cells as they increase in distance from theroot tip, and sustains root-hair outgrowth.
Journal ArticleDOI
Temporal repression of core circadian genes is mediated through EARLY FLOWERING 3 in Arabidopsis
Laura E. Dixon,Kirsten Knox,László Kozma-Bognár,Megan M Southern,Alexandra Pokhilko,Andrew J. Millar +5 more
TL;DR: It is demonstrated that ELF3 associates physically with the promoter of PSEUDO-RESPONSE REGULATOR 9 (PRR9), a repressor of CCA1 and LHY expression, in a time-dependent fashion, which reconciles the functions of ELf3 in the clock network during the night and points to further effects ofELF3 during the day.
Journal ArticleDOI
Data assimilation constrains new connections and components in a complex, eukaryotic circadian clock model
Alexandra Pokhilko,Sarah K. Hodge,Kevin Stratford,Kirsten Knox,Kieron D. Edwards,Adrian W Thomson,Takeshi Mizuno,Andrew J. Millar +7 more
TL;DR: The results suggest that the activation of important morning‐expressed genes follows their release from a night inhibitor (NI), and the model's feedback circuit is revised and now includes PSEUDO‐RESPONSE REGULATOR 7 (PRR7) and ZEITLUPE and gains robustness to parameter variation.
Journal ArticleDOI
AXR3 and SHY2 interact to regulate root hair development.
TL;DR: A general model for auxin signalling is suggested in which the modulation of the relative abundance of different Aux/IAA proteins can determine which down-stream responses are induced, and suggests that root hair initiation is controlled by the Relative abundance of SHY2 and AXR3 in a cell.
