VdPAT1 encoding a pantothenate transporter protein is required for fungal growth, mycelial penetration and pathogenicity of Verticillium dahliae
Published 2025-01-01“…In previous study, we identified a pantothenate transporter gene (VdPAT1) in V. dahliae which can be induced by root exudates from a susceptible cotton variety.MethodsIn this study, we generated VdPAT1 deletion mutants and complementary strain via homologous recombination by a PEG-mediated transformation method and used for the gene functional characterization.Results and discussionThe VdPAT1 deletion mutants displayed reduced colony growth, melanin production, spore yield and germination rate, showed abnormal mycelial branching and decreased ability of mycelial penetration and utilization of nutrients (carbon, amino acids and vitamin), leading to a lower pathogenicity. …”
