Ectomycorrhizal fungi recruit hyphae-associated bacteria that metabolize thiamine to promote pine symbiosis.

ABSTRACT: Ectomycorrhizal fungi form symbiotic relationships with a wide range of terrestrial plants, acquiring carbohydrates for themselves and promoting nutrient uptake in their host plants. However, some ectomycorrhizal fungi cannot effectively obtain the thiamine necessary for growth from their host or synthesize it themselves. Ectomycorrhizal fungi can recruit hypha-associated microorganisms, which play a vital role in promoting nutrient absorption and ectomycorrhizal root formation, ultimately colonizing within fruiting bodies to form a unique bacterial microbiota. In this study, nontargeted metabolomics and whole-genome sequencing were employed to investigate the colonization characteristics of the hyphae-associated bacterium Bacillus altitudinis B4 on the mycelial surface of ectomycorrhizal
