Unveiling the Unique Mitogenome Structure of <i>Phylloporus</i>: Implications for Phylogeny and Evolution in Boletaceae.

ABSTRACT: The genus Phylloporus (Boletaceae, Boletales) is a group of ectomycorrhizal fungi, distinguished from other members of Boletaceae by its unique lamellate hymenophore. Although some molecular data exist for this genus, its mitogenomic characteristics remain poorly understood. In our study, we sequenced, assembled, and annotated the complete mitogenomes of eight species representing seven major subclades of Boletaceae collected in Jiangxi Province, China, with a focus on four Phylloporus species. We found that Phylloporus mitogenomes are circular, ranging in size from 35,117 bp to 38,908 bp, and contain 14-15 core protein-coding genes (PCGs), 24-28 tRNA genes, and 2 rRNA genes. Our comparative analysis revealed that Phylloporus species share many features, such as
