Abstract: The complete mitochondrial genomes of Trichoderma sp. strains DL1-3 (29,197 bp), KC1-1 (27,631 bp), and PAR10 (29,122 bp), isolated from grapevine leaves, were obtained. All strains contained 25 or 26 tRNA genes, two rRNA genes, and 15 core mitochondrial protein coding genes. Phylogenetic trees made with housekeeping region and mitochondrial sequences placed these strains in the T. harzianum clade, with DL1-3 and PAR10 as potential novel species, and KC1-1 identified as a strain of T. harzianum. This suggests that complete mitochondria genome comparisons provide valuable information in resolving questions of species identification, including putatively identifying those that are novel.
