17 Questions
Where did lineages of Strobilomyces and Afroboletus initially associate with ECM hosts?
African hosts
Which region did Strobilomyces and Afroboletus later switch to after being associated with Dipterocarpoideae in tropical Asia?
Eurasian temperate trees
What major event is believed to have driven a burst in the diversification of ECM genera?
Host shifts to temperate host trees
Which host tree type in the Eurasian regions caused an expansion of the distribution range of ECM fungi?
Fagaceous trees
What led to a rapid radiation of the fungi according to the study?
Shifts to temperate host trees in Eurasian regions
How many species are estimated to belong to ectomycorrhizal (ECM) fungi globally?
20,000 - 25,000 species
Which fungal phyla do ectomycorrhizal (ECM) fungi predominantly belong to?
Basidiomycota
Which of the following is NOT a family of dominant trees associated with ectomycorrhizal (ECM) fungi?
Arecaceae
What distinguishes generalist mycorrhizal fungi from specialist ones?
Specialists have strong host preferences
How do mycorrhizal fungi respond to plant roots during association?
They respond to chemical signals emitted by plant roots
Why is biochemical 'crosstalk' between mycorrhizal fungi and plants essential?
To establish a mutualistic relationship
What is the lateral branching pattern in roots of most plants that have ECM associations called?
Heterorhizy
Why do short roots grow much more slowly than long roots in plants with ECM associations?
To allow ECM fungi time to form an association
What environmental change could potentially lead to increased diversification rates of ECM fungi?
Encountering different environmental conditions
From the paper mentioned, what effect did host shifts have on the diversification rates of ectomycorrhizal fungi?
Increased diversification rates
Which type of plants were part of the Fagaceae/Pinaceae host category for Strobilomyces and Afroboletus fungi?
Oak and Pine trees
What does rapid diversification on a phylogenetic tree indicate?
Many species evolving quickly
Explore the global species richness and associations of ectomycorrhizal (ECM) fungi with dominant trees in temperate and tropical forests. Learn about the families of trees commonly associated with these fungi and the diversity within Basidiomycota, Ascomycota, and non-Dikarya fungi.
