Regulation of Stomatal Tropism and Infection by Light in Cercospora zeae-maydis: Evidence for Coordinated Host/Pathogen Responses to Photoperiod?
Figure 5
CRP1 regulates appressorium formation and stomatal tropism in C. zeae-maydis.
A, leaves inoculated with wild type, the Δcrp1-24 mutant, and Δcrp1-40 mutant were observed with electron microscopy. Stomata are indicated with black arrows. B, ratio of appressoria formed per stomate encountered for the wild type and Δcrp1 mutants. Ratio was calculated by counting how many appressoria were formed by 100 arbitrarily selected hypha that had physically encountered a stomate.
