Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics
New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Unlocking grass leaf development: foundations for tunable cereal design
New 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

New Phytologist, Volume 248, Issue 2, Page 690-705, October 2025.Summary Abscisic acid (ABA) induces stomatal closure, reducing transpirational water loss, a critical adaptation for agriculture under drought. However, ABA is often viewed cautiously as stomatal closure limits CO2 uptake for photosynthesis and growth.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition
American Journal of Botany, Volume 112, Issue 7, July 2025.Abstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐
