Function of the Mitochondrial Transport Protein BcMtp1 in Regulating Vegetative Development, Asexual Reproduction, Stress Response, Fungicide Sensitivity, and Virulence of Botrytis cinerea.

ABSTRACT: In model fungi, mitochondrial transport proteins (MTPs), also known as "mitochondrial carriers" (MC), are known to facilitate the exchange of biochemical substances across the mitochondrial inner membrane. In this study, we characterized an MTP in Botrytis cinerea homologous to the known MTPs in Saccharomyces cerevisiae designated BcMtp1. The BcMtp1 deletion mutant phenotype was strikingly defective in vegetative development, conidiation, and sclerotia production. In addition, ΔBcMtp1 showed increased sensitivity to osmotic stress, oxidative stress, and cell wall biogenesis inhibitors. In the pathogenicity assay, ΔBcMtp1 displayed compromised virulence on various host-plant tissues. The BcMtp1 deletion mutant phenotype was rescued by transforming t
