Omics approaches to investigate pre-symbiotic responses of the mycorrhizal fungus Tulasnella sp. SV6 to the orchid host Serapias vomeracea

This research explores how orchid-associated fungi sense and respond to their host plants before they even make physical contact. Scientists used advanced molecular techniques to track changes in gene expression and chemical composition in Tulasnella fungal cells when exposed to orchid plants. The fungi showed significant metabolic preparation, increasing production of proteins and cellular membrane components, suggesting they are actively preparing for symbiosis. This study reveals that plant-fungus interactions begin through long-distance chemical communication before the organisms ever physically meet.

Genetic Characterisation of the Bacterial Microbiota Associating With a Strain of Epichloë Fungal Endophyte of Perennial Ryegrass and the Interaction With Its Paenibacillus Members

mycolabadmin

Researchers discovered that cultures of a fungal endophyte found in perennial ryegrass contain complex bacterial communities dominated by Paenibacillus bacteria. These bacterial cells live on the surface of fungal filaments and regulate each other’s populations through antagonistic interactions, with one strain (E300) acting as a keystone species that controls the community structure. Despite these dynamic bacterial changes, the fungal host’s growth remained unaffected, suggesting a balanced symbiotic relationship important for the grass’s agricultural performance.

Cellular anatomy of arbuscular mycorrhizal fungi

mycolabadmin

This comprehensive review explains the unique cellular structure of arbuscular mycorrhizal fungi, which form vast underground networks connecting plants to soil nutrients. These fungi are remarkable because their hyphae lack internal walls, allowing nutrients and organelles to flow freely throughout their continuous cytoplasm. By synthesizing current knowledge about how these fungi are organized and function at the cellular level, the authors highlight how this organization enables the complex nutrient exchange that supports plant growth and ecosystem health worldwide.
