Fub1 is required for the production of fusaric acid (FA) and its derivatives in Fusarium oxysporum. (A) The amounts of FA and fusarinolic acid (FnA) in cultures of the indicated strains, grown for 3 days on potato dextrose agar (PDA) or Czapek‐Dox agar (CDA), were quantified by liquid chromatography/tandem mass spectrometry and expressed as nanograms per millilitre of extract. (B) The quantification of beauvericin (Bea) and bikaverin (Bik) was performed as in (A). wt, wild‐type strain. Bars represent standard errors from two independent fungal cultures. *P < 0.05; **P < 0.001; ns, not significant.
