Conserved spatial patterning of gene expression in independent lineages of C4 plants
New Phytologist, Volume 249, Issue 1, Page 24-38, January 2026.Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

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
