Discriminate analyses of (a) S. flava and (b) S. graminum transcriptional profiles. Discriminate analysis (DA) was performed using principal components as covariates using the ‘prcomp’ function in R and JMP12 for DA. Principal components that explained 80% of the total variance in the data were used as covariates in the DA analysis. Red indicates BCK60 samples, blue indicates Summer, green indicates Kanlow, and black indicates starvation. The 12 and 24 h timepoints are represented by circles and triangles, respectively. Colored circles represent the 95% confidence intervals around the true mean for each treatment.
