Disruption of a major facilitator superfamily transporter responsible for acetic acid efflux, increases the virulence of the insect pathogenic fungus Metarhizium rileyi
Highlights • Deficiency of MrMFS1 was confirmed to underlie to the accelerated growth. • No morphological or physiological alterations were observed upon deletion of MrMFS1 . • The deletion mutant exhibits enhanced stress tolerance and insecticidal activity. • MrMFS1 mediates the proton-coupled efflux of acetic acid.
