Abstract
Trichoderma Persoon (1794) is a genus of fungus found in soils and decaying wood all over the world. We present the assembly and annotation of the mitochondrial genome of Trichoderma cerinum Bissett, Kubicek & Szakacs (2003) and an assessment of the phylogeny of the group, discussing the loss and gain of shared genes in the evolutionary history of fungi. We downloaded the raw data of T. cerinum from the NCBI database and exported it to the Galaxy Europe platform, where we performed the mitogenome assembly using the NOVOplasty tool. We used three tools for annotation. The phylogeny was conducted with 12 Trichoderma species and the T. cerinum. Fusarium oxysporum was used as an outgroup. We got a circularized mitochondrial genome of 26,696 bp, with 15 protein-coding genes, 25 tRNAs, two rRNAs, two endonuclease sequences, and an orf40. This species contains only one intron in the cob gene. In our phylogenetic reconstruction, T. cerinum was recovered as a sister group of a clade containing Trichoderma lixii, Trichoderma afroharzianum, Trichoderma simmonsii, and Trichoderma harzianum.
