To achieve this, we conducted whole-genome resequencing of 23 <i>N. laricinum</i> isolates collected from three major provinces-Heilongjiang, Inner Mongolia, and Jilin-that represent distinct climatic zones ranging from cold-temperate to relatively warmer regions.

Population structure analyses, including principal component analysis and phylogenetic tree, revealed clear genetic differentiation aligning with geographic origin and climate. Functional annotation (GO and KEGG) highlighted enrichment in metabolic, stress-response, and membrane transport pathways, suggesting potential adaptation to varied temperature regimes and environmental pressures. Moreover, region-specific variants-particularly missense and stop-gain mutations-were linked to genes involved in ATP binding, oxidoreductase activity, and cell division, underscoring the fungus's capacity for rapid adaptation.
