Which tree family was initially associated with the lineages of Strobilomyces and Afroboletus?
Caesalpinioideae
What factor is suggested to have driven a burst in the diversification of ECM genera?
Major host-shift events
Which type of host trees in Eurasian regions triggered a rapid radiation of the ECM fungi?
Fagaceous
What type of trees were Strobilomyces and Afroboletus initially associated with in African regions?
Caesalpinioideae
How many species of ectomycorrhizal fungi are estimated globally?
20,000 - 25,000 species
Which fungal group do the majority of ectomycorrhizal fungi belong to?
Basidiomycota
Which of the following is NOT a family of trees associated with ectomycorrhizal fungi?
Arecaceae
What is the role of chemical signals in the association between mycorrhizal fungi and plant roots?
Aiding in the establishment of mutualism
What characteristic distinguishes generalist ectomycorrhizal fungi from specialists?
They form associations with many different plant families
Why is it important for plant roots to distinguish between beneficial and harmful microbes?
To ensure mutualistic relationships and avoid pathogens
What is the lateral branching pattern in roots of plants with ECM associations called?
Heterorhizy
Why do short roots normally grow much more slowly than long roots in plants with ECM associations?
To allow ECM fungi time to form an association
What may create conditions for speciation in ECM fungi as they encounter different environmental conditions?
Host shifts during association formation
Which paper provides evidence that ECM diversification rates increased during hostshift events within the Strobilomyces– Afroboletus clade?
Sato, H., Tanabe, A.S., & Toju, H. (2017). Host shifts enhance diversification of ectomycorrhizal fungi
Which category of host plants do Strobilomyces and Afroboletus fungi belong to?
Fagaceae/Pinaceae
What indicates rapid diversification when observing a phylogenetic tree like the one described in the text?
The appearance of many species across a short horizontal interval
