Earth observation reveals reduced winter wheat growth and the importance of plant available water during drought (2025)
Journal Article
Sjulgård, H., Graf, L. V., Colombi, T., Hirte, J., Keller, T., & Aasen, H. (in press). Earth observation reveals reduced winter wheat growth and the importance of plant available water during drought. Biogeosciences, 22(5), 1341-1354. https://doi.org/10.5194/bg-22-1341-2025

Drought poses increasing challenges to global food production. Knowledge about the influence of drought on crop development and the role of soil properties for crop drought severity is important in drought risk analysis and for mitigating drought imp...

Root Circumnutation Reduces Mechanical Resistance to Soil Penetration (2024)
Journal Article
Leuther, F., Iseskog, D., Keller, T., Larsbo, M., Pandey, B. K., & Colombi, T. (2025). Root Circumnutation Reduces Mechanical Resistance to Soil Penetration. Plant, Cell and Environment, 48(2), 1608-1620. https://doi.org/10.1111/pce.15219

Root circumnutation, the helical movement of growing root tips, is a widely observed behaviour of plants. However, our mechanistic understanding of the impacts of root circumnutation on root growth and soil exploration is limited. Here, we deployed a...

Root plasticity vs. elasticity – When are responses acclimative? (2024)
Journal Article
Colombi, T., Pandey, B. K., Chawade, A., Bennett, M. J., Mooney, S., & Keller, T. (2024). Root plasticity vs. elasticity – When are responses acclimative?. Trends in Plant Science, 29(8), 856-864. https://doi.org/10.1016/j.tplants.2024.01.003

Spatiotemporal soil heterogeneity and the resulting edaphic stress cycles can be decisive for crop growth. However, our understanding of the acclimative value of root responses to heterogeneous soil conditions remains limited. We outline a framework...
