This study identifies how root responses to mechanical heterogeneity depend on pore geometry and root-soil biomechanics using artificial substrates and imaging.

This study examines how root tip morphology affects mechanical efficiency and growth rate trade-offs in plants using a quantitative framework.

This study tracks Bacillus subtilis movement in soil to show how bacteria modify fluid pathways to enhance collective transport during root colonisation.

The paper shows that bacterial motility reduces surface tension in soil, enhancing water infiltration and rewetting.

The paper investigates how root exudates enhance water infiltration in dry soil, reducing evaporation and improving drought resistance in crops.

The paper develops a model incorporating rhizodeposits' effects on soil water transport and finds their impact on root water uptake varies with precipitation and root maturity.

The paper develops a microcosm fabrication platform for live microscopy of plant-soil systems, enabling controlled water content and observation of root-soil interactions.

This paper models how root systems affect soil water distribution during drought, showing that root architecture and preferential flow influence water retention and loss.

The paper develops a particle-based model to study how plant roots adjust tissue mechanical properties to grow in hard soil, finding that cell wall softening at the tip and changes in cell elongation zones are key mechanisms.

The paper develops a model that predicts how root system architecture affects soil water infiltration by incorporating preferential flow along root axes.
