Polypores, or bracket fungi, are crucial to forest ecosystems. This study identified 4,026 species across 11 orders in the class Agaricomycetes, highlighting Polyporales and Hymenochaetales as most diverse. Asia hosts the most species, while tropical areas lead in species richness. Key findings indicate habitat-specific distributions, providing a basis for conservation efforts.

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are crucial secondary metabolites across various organisms. This study uncovers a subclass of leaderless RiPPs in fungi, challenging the traditional framework. Using bioinformatics and chemical analyses, researchers identified these abundant peptides in invasive Amanita phalloides, highlighting their potential role in the species' proliferation.

Pesticide residues, chemicals intended to repel pests, were found in 70% of soil samples from 373 European sites, according to a comprehensive survey. The presence of these residues significantly alters both taxonomic and functional soil biodiversity. The findings highlight a substantial impact on soil fungi, calling into question the ecological risk assessments of pesticides within soil ecosystems.

Carbon–phosphorus exchange rate constrains density–speed trade-off in arbuscular mycorrhizal fungal growth

2026-02-06
Proceedings of the National Academy of Sciences of the United States of America • Level 3 (24 panels)
Corentin Bisot, Loreto Oyarte Gálvez, Félix Kahane, Marije van Son, Bianca Turcu, Rob Broekman, Kai-Kai Lin, Paco Bontenbal, Max Kerr Winter, Vasilis Kokkoris, Stuart A. West, Christophe Godin, E. Kiers, Thomas S. Shimizu

Arbuscular mycorrhizal fungi form symbiotic relationships with plants, exchanging phosphorus for carbon, crucial for ecosystem productivity and climate regulation. This study utilized an automated pipeline to analyze fungal network growth, revealing how carbon-phosphorus exchange rates influence the density-speed trade-off in fungal growth, offering insights into symbiotic nutrient exchange dynamics.
