Abstract

The filamentous fungus Talaromyces liani (Kamyschko) Yilmaz, Frisvad & Samson, 2014, has attracted considerable interest in biotechnology due to its diverse industrial applications and physiological characteristics. However, the mitochondrial genome of T. liani remains uncharacterized. Here, we present the complete mitochondrial genome of T. liani, comprising 38,000 bp with a GC content of 24.61%. This genome includes 15 core protein-coding genes, 4 independent ORFs, 6 intronic ORFs, 26 tRNAs, and 2 rRNA genes. Phylogenetic analysis using Bayesian inference (BI) revealed the evolutionary relationships among 15 fungi from Eurotiales, strongly supporting distinct clades and indicating that T. liani most closely related to T. pinophilus.
