The ... -
Freeing Aspergillus fumigatus of Polymycovirus Infection Renders It More Resistant to Competition with Pseudomonas aeruginosa Due to Altered Iron-Acquiring Tactics
Patil, Rutuja H.; Kotta-Loizou, Ioly; Palyzová, Andrea; Pluháček, Tomáš; Coutts, Robert H. A.; Stevens, David A.; Havlíček, Vladimír (2021-06-22)A virus-free (VF) A. fumigatus isolate has been shown to be resistant in competition with Pseudomonas as compared to the isogenic line infected with Aspergillus fumigatus polymycovirus 1 (AfuPmV-1), and this phenotype was ... -
Identification and sequence determination of a new chrysovirus infecting the phytopathogenic fungus Dothistroma septosporum
Shah, Unnati A.; Daudu, John O.; Filippou, Charalampos; Tubby, Katherine V.; Coutts, Robert H. A.; Kotta-Loizou, Ioly (2023-04-18)A new double-stranded (ds) RNA mycovirus has been identified in isolate Ds752-1 of the phytopathogenic fungus Dothistroma septosporum, the causal agent of Dothistroma needle blight, also known as red band needle blight or ... -
