Genome Sequence of the Fungus Trichoderma asperellum SM-12F1 Revealing Candidate Functions of Growth Promotion, Biocontrol, and Bioremediation

Abstract

Trichoderma spp. are versatile probiotic fungi that are known to promote plant growth and disease resistance under biotic stress, abiotic stress, or both. They are often used to prevent plant diseases caused by pathogens, act as biofertilizers, and are used in mycoremediation. In our previous study, Trichoderma asperellum strain SM-12F1 was isolated from soils contaminated with arsenic (As), adjacent to a realgar mine. SM-12F1 promoted plant growth and was useful for biocontrol and bioremediation. However, the genomic sequence of this strain was not characterized. This study aimed to generate high-quality genome resources for T. asperellum SM-12F1, and to determine the genomic basis of mechanisms behind plant growth promotion, biocontrol, and bioremediation of As in soil. Genome data of this fungus will provide perspectives on the molecular basis underlying biocontrol activity and mycoremediation.[Figure: see text] Copyright © 2021 The Author(s).
