Unlocking grass leaf development: foundations for tunable cereal design

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1655-1676, November 2025.
Summary The grass leaf plays a critical role in global food security, generating the carbon stores in cereal grains, which provide > 50% of global calories. As the global population grows, there is an urgent need to increase food production using fewer resources and to develop more resilient agricultural systems to withstand variable climate conditions

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

open access: yesNew 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.
