Comparative Genomics Reveals Species-Specific Genes and Symbiotic Adaptations in Tricholoma matsutake.

ABSTRACT: Tricholoma matsutake, a highly valued ectomycorrhizal fungus, requires a symbiotic relationship with pine trees for growth, complicating its cultivation. This study presents a comprehensive comparative genomic analysis of Tricholoma species, with a focus on T. matsutake. Genomic data from 19 assemblies representing 13 species were analyzed to identify genus-, species-, and strain-specific genes, revealing significant evolutionary adaptations. Notably, T. matsutake exhibits a higher proportion of repetitive elements compared to other species, with retrotransposons like LTR Gypsy dominating its genome. Phylogenomic analyses showed that T. matsutake forms a monophyletic group closely related to T. bakamatsutake. Gene family expansion and contraction a
