Mitochondrial DNA B Resour. 2024 Jun 10;9(6):716-719. doi: 10.1080/23802359.2024.2356131. eCollection 2024.

Abstract

The complete mitochondrial genome of Squamanita imbachii I. Saar, is unveiled in this research for the first time. It covers 76,643 base pairs (bp) and exhibits a guanine-cytosine (GC) content of 23%. The genome includes 14 conserved protein-coding genes, 1 DNA polymerase gene, 2 ribosomal RNA gene (RNS and RNL), 25 transfer RNA (tRNA) genes and 18 open reading frames (ORFs). Phylogenetic analysis, utilizing a mitochondrial gene dataset from 15 taxa across seven families within the Agaricales order, was conducted employing the maximum-likelihood (ML) approach. This analysis identified a close phylogenetic relationship between S. imbachii and Floccularia luteovirens (Alb. & Schwein.) Pouzar 1957, positioning both within the Squamanitaceae family.
