Current status and challenges of ecological studies on ectomycorrhizal fungi of the genus Rhizopogon

Abstract

Ectomycorrhizal fungi play an important role in forest ecosystems. In recent years, forest ecosystems have been subjected to unprecedented pressure due to changes in the natural environment, including climate change, and anthropogenic influences. Forest trees establish symbiotic relationships with a diverse range of ectomycorrhizal fungi possessing various ecological characteristics. Understanding the individual traits of these fungal species is crucial for predicting adaptation to future environmental changes. DNA information has brought many benefits to mycology and has greatly contributed to the ecology of ectomycorrhizal fungi. This review provides an overview of previous research focusing on the genus Rhizopogon and introduces the author's research findings as a case study in alpine ecosystems. Furthermore, this review discussed current challenges and future research directions in the ecological studies of ectomycorrhizal fungi.
