Disruption of CRP1 affects cercosporin biosynthesis.

A, Conidia (105) were spread on 0.2× PDA, and incubated for three days and seven days in constant white light. DAI = days after inoculation. B, Quantification of cercosporin biosynthesis in various light conditions. Cercosporin was measured from wild type and Δcrp1-24 cultures grown on 0.2× PDA in constant white, blue, red light and darkness for seven days.
