PLETHORAs shape Arabidopsis phyllotaxis through modulation of patterning robustness and accelerated inflorescence development

New Phytologist, Volume 249, Issue 1, Page 495-511, January 2026.
Summary Phyllotaxis is the arrangement of lateral organs on a stem axis, which in Arabidopsis follows a spiral pattern. We previously described that loss of three PLETHORA (PLT) transcription factors shifts the phyllotactic spiral to novel metastable patterns, but the mechanism behind these shifts remained unclear.

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

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 ...

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

New 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,

Mycelial dynamics in arbuscular mycorrhizal fungi

New Phytologist, Volume 249, Issue 2, Page 691-713, January 2026.
Summary Arbuscular mycorrhizal fungi (AMF), similar to other filamentous fungi, develop extensive hyphal networks collectively known as mycelia. AMF mycelia are complemented by a variety of specialized structures such as spores, vesicles, and auxiliary cells, which together form integrated and functionally diverse AMF networks.
