FIG. 5.

Regulated expression of aflR and omtA in A. parasiticus (A) and A. oryzae (B). A. parasiticus NRRL 3386 (A) and A. oryzae NRRL 451 (B) grown at 29°C in PMS medium for 48 h were transferred to GMS medium and grown at 29 or 37°C for another 24 h. Fungal mycelia were harvested at the time of transfer (0 h) and after transfer (24 h). Western blot analysis and RPA were conducted as described in the legend to Fig. 3. The results are shown in the top panels. The accumulation of AFB₁ is shown in the bottom panels.
