FdUrd, 6-azauridine, miracil D, 5-fluorouracil, and cycloheximide inhibited photoinduced conidiation at the appropriate concentrations. Suppression of conidiation was greater when these inhibitors were added just before, rather than after, the photoinduction period. Actinomycin D and puromycin, both at 10−4 to 10−6 m, were ineffective. Incorporation of labelled precursors into nucleic acids and protein in the presence of FdUrd, miracil D, 5-fluorouracil and cycloheximide was greatly suppressed. The results suggest the involvement of nucleic acids and proteins in light-induced conidiation in B. cinerea. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-103-1-153
