Differential regulation of toxoflavin production and its role in the enhanced virulence of Burkholderia gladioli.

abstract：:A large number of effector candidates have been identified recently in powdery mildew fungi. However, their roles and how they perform their functions remain unresolved. In this study, we made use of host-induced gene silencing and confirmed that the secreted barley powdery mildew effector candidate, CSEP0055, contrib...
