Reducing production of type B trichothecenes by Fusarium graminearum on cereals is necessary to control contamination, prevent yield reduction and protect human and animal health. Thus, an understanding of how trichothecene biosynthesis is induced is essential. The effect of ambient pH on fungal growth, toxin biosynthesis and expression of TRI genes was studied during in vitro liquid culture of F. graminearum on minimal medium. Fungal development stopped at day 3 after a sharp pH drop in the… CONTINUE READING
