Mitochondrial Genome Resource of a grapevine strain of Trichoderma harzianum, a potential biological control agent for fungal canker diseases

Abstract

Trichoderma spp. are commonly used as bioremediation agents, biological controls, and for making biofuels. Herein, a Trichoderma harzianum strain PAR3 was isolated from grapevine roots in central California, USA. As part of a larger whole genome sequencing effort, the mitochondrial genome (mitogenome) sequence was obtained for the PAR3 strain. The mitogenome is 27,631 bp containing genes of 14 core mitochondrial proteins, 25 tRNA, and two rRNAs and a GC% content of 27.55%. BLAST search using the PAR3 mitogenome as query against GenBank sequence database showed mitogenome MUT3171 (29,791 bp) of Trichoderma lixii was the most similar (Query Coverage = 99%; Percentage Identity=100.00%) with two major deletions, 1,339 bp and 821 bp. The PAR3 mitogenome sequence will provide a useful reference for comparing different Trichoderma strains from US and around the world.
