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

Functional Diversity of Neotropical Aquatic Hyphomycetes: Insights Into Environmental Drivers

Biotropica, Volume 57, Issue 6, November 2025.
Subtropical streams host diverse hyphomycete assemblages than tropical one's. Larger saprotrophs with diverse conidia shapes dominate in subtropical areas. Cold and oxygenated waters have a positive effect on functional diversity. Poor litter in tropical favored the dominance of wood saprotrophs and endophytes.
