An arbuscular mycorrhiza from the 407‐million‐year‐old Windyfield Chert identified through advanced fluorescence and Raman imaging

open access: yesNew 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 ...

Memory in the wall: expanding our understanding of the roles of plant cell walls

open access: yesNew Phytologist, Volume 249, Issue 1, Page 56-72, January 2026.
Summary The plant cell wall, while providing mechanical support to cells, also dynamically adjusts its composition and structure in response to cellular and environmental cues. Recent findings indicate that plants exposed to cold stress alter the composition of cell wall polysaccharides and that this altered status primes the plants to overcome future,

Unraveling mannan biosynthesis in poplar and spruce: functional characterization of Cellulose Synthase‐Like family A (CSLA) genes

open access: yesNew Phytologist, Volume 249, Issue 1, Page 282-298, January 2026.
Summary Hemicelluloses are key chemical constituents of plant cell walls, influencing structure, strength, and interactions between cellulose and lignin. While xylan has been widely studied and shown to affect cell wall integrity, the function of mannan remains largely unexplored.
