Sebacinales Everywhere: Previously Overlooked Ubiquitous Fungal Endophytes

摘要: Inconspicuous basidiomycetes from the order Sebacinales are known to be involved in a puzzling variety of mutualistic plant-fungal symbioses (mycorrhizae), which presumably involve transport mineral nutrients. Recently few members this fungal not fitting definition and commonly referred as ‘endophytes’ have raised considerable interest by their ability enhance plant growth increase resistance host plants against abiotic stress factors pathogens. Using DNA-based detection electron microscopy, we show that only extremely versatile mycorrhizal associations, but also almost universally present symptomless endophytes. They occurred field specimens bryophytes, pteridophytes all families herbaceous angiosperms investigated, including liverworts, wheat, maize, non-mycorrhizal model Arabidopsis thaliana. were habitats studied on four continents. We even detected these fungi herbarium originating pioneering trips North Africa 1830s/40s. No geographical or patterns detected. Our data suggest multitude interactions may arisen an ancestral endophytic habit specialization. Considering proven beneficial influence ubiquity, previously unrecognized universal hidden force ecosystems.
