Scholarcy highlights

  • Plant hybridization is common and important in ecological and economic contexts, little is known about the impact of plant hybridization on ectomycorrhizal fungal communities in natural habitats
  • (1) Cross type influenced EMF composition, with communities on hybrids being distinct from their parents
  • (2) Cross type influenced the composition of hyphal exploration types important for soil resource foraging, contact and short distance exploration types were dominant on all cross types
  • (3) Cross type had a marginal influence on EMF colonization, with P. angustifolia highest and P. fremontii lowest
  • These results highlight the potential for tree hybridization to structure belowground communities in heterogeneous natural ecosystems
