Popis: Numerous allelopathic plant secondary metabolites impact plant–microorganism interactions by injuring plant-associated beneficial bacteria and fungi. Fungi belonging to the genus Trichoderma positively influence crops, including benzoxazinone-containing maize. However, benzoxazinones and their downstream metabolites such as benzoxazolinone and phenoxazinones are often fungitoxic. Specimen Trichoderma viride F-00612 was found to be insensitive to 100-µM phenoxazinone and 500-µM benzoxazolinone. Screening of 46 additional specimens of ascomycetes revealed insensitivity to phenoxazinones among fungi that cause disease in benzoxazinone-producing cereal crops, whereas many other ascomycetes were highly sensitive. In contrast, most of the screened fungi were insensitive to benzoxazolinone. T. viride F-00612 was associated with bacteria and, thus, existed as a consortium. By contrast, Enterobacter species and Acinetobacter calcoaceticus were prominent in the original specimen, and Bacillus species predominated after antibiotic application. Prolonged cultivation of T. viride F-00612 in liquid medium and on Czapek agar in the presence of T. viride F-00612 consortium may contribute to the ability to manage benzoxazinone downstream products and facilitate BOA-6-OH degradation via nitration.
