Results of pairwise differential expression analysis using only the samples collected in May 2012. A Results of exploratory PCA to qualitatively screen for differences between treatment groups. There was a clear qualitative difference between the control and L. daturaphila-induced samples driven by PC1. B Volcano plot showing the relationship between significance and fold-change for each gene in our D. wrightii genome annotation. A change of 2/-2 is marked for reference but was not used as a cutoff for any analysis. Significant genes (p < 0.05) are shown in red, non-significant genes in black
