Bacterial and fungal communities associated with Tuber magnatum-productive niches.

摘要: Abstract Truffles are hypogeous ectomycorrhizal fungi of ecological interest for forestry in soils the northern hemisphere, and economical relevance food markets worldwide. The molecular mechanisms that control truffle body formation largely unknown, as well environmental factors likely involved. Among latter, it has been hypothesized soil‐borne communities may have an impact on production. To address this question, we investigated bacterial fungal resident productive versus adjacent non‐productive grounds white Tuber magnatum by using PCR‐DGGE. Although were generally highly similar across all samples within grounds, profiles did cluster according to productivity circumscribed niches, a Moraxella osloensis population appeared be associated with sites. Fungal revealed several populations, yet showed no obvious patterns relation productivity, although Mortier...
