Identification of catalase as an early up-regulated gene in Beauveria bassiana and its role in entomopathogenic fungal virulence.

Highlights: [•] Catalases are involved in stress tolerance and infection in entomopathogenic fungi. [•] CatE7 gene was identified in B. bassiana via suppression subtractive hybridization. [•] The catalase gene (catE7) was homologous to monofunctional fungal catalases. [•] A transgenic strain over-expressing BbcatE7 displayed enhanced virulence. [Copyright &y& Elsevier]
