Elementary effects for models with dimensional inputs of arbitrary type and range: Scaling and trajectory generation (2023)
Journal Article

The Elementary Effects method is a global sensitivity analysis approach for identifying (un)important parameters in a model. However, it has almost exclusively been used where inputs are dimensionless and take values on [0, 1]. Here, we consider mode...

Long-distance hormone transport via the phloem (2023)
Journal Article

Several key plant hormones are synthesised in the shoot and are advected within the phloem to the root tip. In the root tip, these hormones regulate growth and developmental processes, and responses to environmental cues. However, we lack understandi...

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...

Differential biosynthesis and cellular permeability explain longitudinal gibberellin gradients in growing roots (2021)
Journal Article

Control over cell growth by mobile regulators underlies much of eukaryotic morphogenesis. In plant roots, cell division and elongation are separated into distinct longitudinal zones and both division and elongation are influenced by the growth regula...

OpenSimRoot: widening the scope and application of root architectural models (2017)
Journal Article

© 2017 The Authors. New Phytologist © 2017 New Phytologist Trust OpenSimRoot is an open-source, functional–structural plant model and mathematical description of root growth and function. We describe OpenSimRoot and its functionality to broaden the b... Read More about OpenSimRoot: widening the scope and application of root architectural models.

Root hydrotropism is controlled via a cortex-specific growth mechanism (2017)
Journal Article

Plants can acclimate by using tropisms to link the direction of growth to environmental conditions. Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but whose molecular and cellular basis remains unclear...

Dynamic regulation of auxin oxidase and conjugating enzymes AtDAO1 and GH3 modulates auxin homeostasis (2016)
Journal Article

Auxin is a key hormone regulating plant growth and development. We combine experiments and mathematical modeling to reveal how auxin levels are maintained via feedback regulation of genes encoding key metabolic enzymes. We describe how regulation of...
