Fungal dynamics and lignocellulose depolymerization in Pinus koraiensis: impact of longhorn beetle infestation.

ABSTRACT: Xylophagous insects, like Monochamus saltuarius significantly affect tree-stem-associated microbial communities and pose major threats to forest ecosystems. As a vector for the pinewood nematode (Bursaphelenchus xylophilus) and a wood-boring pest, M. saltuarius infests various Pinus species. Yet, the interactions between M. saltuarius-associated fungi and the endophytic fungi of its host tree, Pinus koraiensis, remain uncharacterized. In this study, high-throughput sequencing was used to characterize fungal communities within infested and uninfested host trees. Endophytic fungi with lignocellulose-depolymerizing potential were identified, and their enzymatic activity was experimentally assessed. A significant reduction in fungal diversity was detected in infested samples, indicating that M
