Elementary effects for models with dimensional inputs of arbitrary type and range: Scaling and trajectory generation (2023)
Journal Article
Rutjens, R. J., Band, L. R., Jones, M. D., & Owen, M. R. (2023). Elementary effects for models with dimensional inputs of arbitrary type and range: Scaling and trajectory generation. PLoS ONE, 18(10), Article e0293344. https://doi.org/10.1371/journal.pone.0293344

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
Collis, H. L., Owen, M. R., & Band, L. R. (2023). Long-distance hormone transport via the phloem. Journal of Theoretical Biology, 562, Article 111415. https://doi.org/10.1016/j.jtbi.2023.111415

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...

Frontiers in Plant Science, 13, Article 1010165. https://doi.org/10.3389/fpls.2022.1010165

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...

Journal of Theoretical Biology, 558, Article 111337. https://doi.org/10.1016/j.jtbi.2022.111337

During the SARS-CoV2 pandemic, epidemic models have been central to policy-making. Public health responses have been shaped by model-based projections and inferences, especially related to the impact of various non-pharmaceutical interventions. Accom...

Modeling root loss reveals impacts on nutrient uptake and crop development (2022)
Journal Article
Schäfer, E. D., Owen, M. R., Band, L. R., Farcot, E., Bennett, M. J., & Lynch, J. P. (2022). Modeling root loss reveals impacts on nutrient uptake and crop development. Plant Physiology, 190(4), 2260-2278. https://doi.org/10.1093/plphys/kiac405

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...

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...
