Scaling Relations for Auxin Waves [PDF]
arXiv, 2022 We analyze an 'up-the-gradient' model for the formation of transport channels of the phytohormone auxin, through auxin-mediated polarization of the PIN1 auxin transporter. We show that this model admits a family of travelling wave solutions that is parameterized by the height of the auxin-pulse.

Spot dynamics in a reaction-diffusion model of plant root hair initiation [PDF]
SIAM Journal of Applied Mathematics, 78(1), 291-319, 2018, 2017 We study pattern formation in a 2-D reaction-diffusion (RD) sub-cellular model characterizing the effect of a spatial gradient of a plant hormone distribution on a family of G-proteins associated with root-hair (RH) initiation in the plant cell Arabidopsis thaliana.

Role of the Arabidopsis PIN6 Auxin Transporter in Auxin Homeostasis and Auxin-Mediated Development
PLoS ONE, 2013 Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone auxin are required for tissue-specific directional auxin transport and cellular auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important roles in developmental processes such as embryogenesis, organogenesis, vascular tissue differentiation, root ...

Auxin response factors are keys to the many auxin doors
New Phytologist, 2022 SummaryIn plants, most developmental programs depend on the action of auxin. The best described model of the auxin signaling pathway, which explains most, but not all, of the auxin transcriptional responses, relies on a de‐repression mechanism. The auxin/indole‐3‐acetic acid repressors (Aux/IAAs) interact with the auxin response factors (ARFs), the ...

Molecular Plant Pathology, Volume 24, Issue 2, Page 154-166, February 2023., 2023 Turnip crinkle virus capsid protein interacts with multiple RNA silencing pathway components that include SUPPRESSOR OF GENE SILENCING 3, as well as previously reported DRB4 and AGO2, to achieve efficient suppression of RNA silencing‐mediated antiviral defence. Abstract Most plant viruses encode suppressors of RNA silencing (VSRs) to protect themselves

Effect of medium-pH and MES on adventitious root formation from stem disks of apple [PDF]
, 2008 We have examined the effect of medium-pH on rooting using 1-mm slices cut from stems of apple microshoots. Before autoclaving, the pH of the rooting medium was set at various pH values between 4.5 and 8.0. During autoclaving, the pH drifted in particular

The clubroot pathogen Plasmodiophora brassicae: A profile update
Molecular Plant Pathology, Volume 24, Issue 2, Page 89-106, February 2023., 2023 The clubroot pathogen wants to conquer the world, and how better than through social media. This Plasmodiophora brassicae profile highlights how the growers are in a constant fight with this devastating pathogen. Art by C.‐É. Brochu. Abstract Background Plasmodiophora brassicae is the causal agent of clubroot disease of cruciferous plants and one of ...

The tetrazole analogue of the auxin indole-3-acetic acid binds preferentially to TIR1 and not AFB5 [PDF]
, 2018 Auxin is considered one of the cardinal hormones in plant growth and development. It regulates a wide range of processes throughout the plant. Synthetic auxins exploit the auxin-signalling pathway and are valuable as herbicidal agrochemicals. Currently, despite a diversity of chemical scaffolds all synthetic auxins have a carboxylic acid as the active ...

The Production of Cauliflower Microshoots using Curd Meristematic Tissues and Hypocotyl–derived Callus. [PDF]
, 2012 The capacity for microshoot production from cauliflower was investigated applying two different protocols. In the first, cauliflower curd meristematic tissue was used as a source of explants.
