Mycoviruses mediate mycotoxin regulation in Aspergillus ochraceus [PDF]

open access: yesEnvironmental Microbiology, 2018
Summary To date, no demonstration of a direct correlation between the presence of mycoviruses and the quantitative or qualitative modulation of mycotoxins has been shown. In our study, we transfected a virus‐free ochratoxin A (OTA)‐producing isolate of Aspergillus ochraceus ...
