Fluctuations in auxin levels depend upon synchronicity of cell divisions in a one-dimensional model of auxin transport (2023)
Journal Article

Auxin is a well-studied plant hormone, the spatial distribution of which remains incompletely understood. Here, we investigate the effects of cell growth and divisions on the dynamics of auxin patterning, using a combination of mathematical modelling...

In silico evidence for the utility of parsimonious root phenotypes for improved vegetative growth and carbon sequestration under drought (2022)
Journal Article

Drought is a primary constraint to crop yields and climate change is expected to increase the frequency and severity of drought stress in the future. It has been hypothesized that crops can be made more resistant to drought and better able to sequest...

Modeling root loss reveals impacts on nutrient uptake and crop development (2022)
Journal Article

Abstract Despite the widespread prevalence of root loss in plants, its effects on crop productivity are not fully understood. While root loss reduces the capacity of plants to take up water and nutrients from the soil, it may provide benefits by decr...

Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development (2021)
Journal Article

During plant development, a precise balance of cytokinin is crucial for correct growth and patterning, but it remains unclear how this is achieved across different cell types and in the context of a growing organ. Here we show that in the root apical... Read More about Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development.

A network of transcriptional repressors modulates auxin responses (2020)
Journal Article

The regulation of signalling capacity, combined with the spatiotemporal distribution of developmental signals themselves, is pivotal in setting developmental responses in both plants and animals. The hormone auxin is a key signal for plant growth and... Read More about A network of transcriptional repressors modulates auxin responses.

Inference of the Arabidopsis lateral root gene regulatory network suggests a bifurcation mechanism that defines primordia flanking and central zones (2015)
Journal Article

A large number of genes involved in lateral root (LR) organogenesis have been identified over the last decade using forward and reverse genetic approaches in Arabidopsis thaliana. Nevertheless, how these genes interact to form a LR regulatory network...
