X‐ray micro‐CT imaging to study foliar water uptake mechanisms in plants with contrasting leaf topography

New Phytologist, Volume 248, Issue 2, Page 656-671, October 2025.
Summary Formation of an aqueous continuum from the leaf surface to the sub‐stomatal cavity is a key process, affecting the foliar entry of solutes, particles, and pathogens. However, the factors controlling the transition from a water droplet to the formation of a continuous water film remain poorly understood.

How the diversity in digestion in carnivorous plants may have evolved

New Phytologist, Volume 247, Issue 6, Page 2581-2590, September 2025.
Summary Carnivorous plants secrete digestive enzymes for prey degradation. Although carnivorous plants have a polyphyletic origin and evolved several times independently, they surprisingly co‐opted similar digestive enzymes during convergent evolution.

Climate adaptation in Populus trichocarpa: key adaptive loci identified for stomata and leaf traits

New Phytologist, Volume 247, Issue 6, Page 2647-2664, September 2025.
Summary We investigated adaptive genetic variation in Populus trichocarpa, a potential biofuel feedstock crop, to better understand how physiological traits may influence tolerance to water limitation. Our study focused on leaf and stomatal traits, given their roles in plant–water relations and adaptation. Using a diversity panel of over 1300 genotypes,
