High diversity in melanin levels is exhibited among strains from four worldwide populations. Gray values of 37 different Z. tritici strains from four different field populations across the world. The colors of the bars indicate the population to which the strains belong. Means and standard errors of the gray values were based on colonies grown for 7Â days. Some examples of Z. tritici strains illustrating the diversity in melanin accumulation are shown in the lower panel. The experiment was performed three times with similar results
