Figure 2.

Effect of compactin on the relative expression of genes responsible for DON biosynthesis and regulation. The expression level for the untreated control was considered as 1.0. EL above or below 1.0 means up- or down-regulation, respectively. Blue bars indicate genes encoding biosynthetic enzymes; red bars indicate genes encoding regulation factors; yellow bar indicates the TRI12 gene encoding transport protein (TRI efflux pump); green bars indicate genes with unknown functions. Each bar is shown as M ± SD; * p < 0.05; ** p < 0.01.
