FIG. 7.

Box plots of percent mature perithecia formed by self-fertilization of wild-type G. zeae and pheromone precursor gene ppg1 and ppg2 and pheromone receptor gene pre1 and pre2 deletion mutants of G. zeae. There are three independent transformants for each class. ppg1-ect is an ectopic-insertion mutant shown as a control. Each box plot shows the 75th and 25th percentiles (upper and lower borders of the box), the median (a solid line within a box), the mean (a dotted line within a box), the 90th and 10th percentiles (upper and lower horizontal lines outside of the box), and outliers (black circles). Box plots with asterisks indicate significant difference from the wild type by Dunnett's test.
