abstract = {Mutualisms with new host lineages can provide symbionts with novel ecological opportunities for expanding their geographic distribution, thereby leading to allopatric speciation. Although ectomycorrhizal (ECM) fungi provide ideal opportunities for testing the relationship between host shift and diversification, their diversification history itself remains uninvestigated. By targeting the ECM fungal genera Strobilomyces and Afroboletus, we here test whether mutualism with new host lineages can increase the symbiont?s diversification rate. Using a Bayesian tree inferred from 23,100-base nucleotide sequences of 80 single-copy genes, we tested whether the diversification rate of the two genera had changed with host category and ancestral host states. The results indicated that these fungi were initially associated with Caesalpinioideae/Monotoideae in Africa, acquired associations with Dipterocarpoideae in tropical Asia after the India-Eurasia collision, and then switched to Fagaceae/Pinaceae and Nothofagaceae/Eucalyptus. Fungal lineages associated with Fagaceae/Pinaceae were inferred to have the diversification rate almost four times larger than those with Caesalpinioideae/Monotoideae, and almost twice larger than those with Dipterocarpoideae or Nothofagaceae/Eucalyptus. Our study suggest that host shift, especially to Fagaceae/Pinaceae in the middle Palaeogene, can provide ecological opportunities for the allopatric speciation of these fungi, supposedly representing an important scenario for diversification history of ECM fungi.}
