Regulation of Stomatal Tropism and Infection by Light in Cercospora zeae-maydis: Evidence for Coordinated Host/Pathogen Responses to Photoperiod?
Figure 2
Effects of light on cercosporin biosynthesis and conidiation of C. zeae-maydis.
A, Conidia (105) were spread on 0.2× PDA medium, and the plates were incubated for four days in constant white light, blue light (400–530 nm), red light (600–700 nm), or darkness. Cercosporin accumulated in the medium as a dark red pigment. B, Conidiation and cercosporin were measured after four days in cultures grown on V8-agar and 0.2× PDA, respectively.
