简介
- Mutualisms with new host lineages can provide symbionts with novel ecological opportunities to expand their geographical distribution, thereby leading to evolutionary diversification. Because ectomycorrhizal (ECM) fungi provide ideal opportunities to test the relationship between host shifts and diversification, we tested whether mutualism with new host lineages could increase the diversification rates of ECM fungi.
- Using a Bayesian tree inferred from 23 027‐base nucleotide sequences of 80 single‐copy genes, we tested whether the diversification rate had changed through host‐shift events in the monophyletic clade containing the ECM fungal genera Strobilomyces and Afroboletus.
- The results indicated that these fungi were initially associated with Caesalpinioideae/Monotoideae in Africa, acquired associations with Dipterocarpoideae in tropical Asia, and then switched to Fagaceae/Pinaceae and …
