摘要： 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, Delta BcMtp1 showed increased sensitivity to osmotic stress, oxidative stress, and cell wall biogenesis inhibitors. In the pathogenicity assay, Delta BcMtp1 displayed compromised virulence on various host-plant tissues. The BcMtp1 deletion mutant phenotype was rescued by transforming the wild-type BcMtp1 variant into the mutant. Together, these data indicate that BcMtp1 is critical for vegetative development, asexual reproduction, stress tolerance, and virulence of B. cinerea.
