The fungus Fusarium graminearum produces a toxin, deoxynivalenol (DON), that can be found in cereal grains and processed food or feed. Here, Huang et al. study the regulation of DON biosynthesis and show that transcription factors TRI6 and TRI10 regulate each other’s expression and that of a long non-coding RNA which, in turn, downregulates a DON biosynthesis gene.
