Tyrosinase plate assay. (A) Parent strain T1P11 and the reporter strain T11-76. Conidia from each strain were harvested and spread on both noninducing and chloramphenicol-containing plates. Conidia on noninducing plates were allowed to grow for 2 days at 30° while conidia on chloramphenicol-containing plates were allowed to grow for 3 days. Tyrosine solution was then added and pictures were taken after incubation with the solution for 24 hr. (B) As for A, but showing mutant isolate E3.
