Journal ArticleDOI
OXI1 kinase is necessary for oxidative burst-mediated signalling in Arabidopsis.

TL;DR: It is shown that expression of an Arabidopsis thaliana gene (OXI1) encoding a serine/threonine kinase is induced in response to a wide range of H2O2-generating stimuli, and OXI1 is an essential part of the signal transduction pathway linking oxidative burst signals to diverse downstream responses.
Journal ArticleDOI
Clonal relationships and cell patterning in the root epidermis of Arabidopsis
Liam Dolan,Catherine M. Duckett,Claire S. Grierson,Paul Linstead,Katharina Schneider,Emily Lawson,Caroline Dean,Scott Poethig,Keith Roberts +8 more
TL;DR: Ectopic hairs are present in the ctr1 root epidermis suggesting that a Raf protein kinase may play a role in pattern formation/differentiation in theroot epider Mis and that ethylene may be a diffusible signal involved in specifying pattern in the root epidersmis.
Journal ArticleDOI
The Arabidopsis Rop2 GTPase is a positive regulator of both root hair initiation and tip growth.
TL;DR: It is concluded that the Arabidopsis Rop2 GTPase acts as a positive regulatory switch in the earliest visible stage in hair development, swelling formation, and in tip growth.
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
Genetic Interactions during Root Hair Morphogenesis in Arabidopsis
TL;DR: A genetic model for root hair morphogenesis is presented that defines the roles of each gene, and hypotheses about functional relationships between genes are suggested, and TIP1 and RHD3 are required much earlier in hair formation than previous studies have suggested.
