From: Transcriptome profiles of Quercus rubra responding to increased O3 stress
Venn diagrams showing number of DEGs from two-year-old seedlings exposed to O3 treatments over time. Times of sampling (7 h, 14 days, and 28 days) are represented by 7 h, 14d, and 28d, respectively. Up- (red) or down-regulation (blue) patterns are also shown for O3 concentrations: A) 80 ppb, B) 125 ppb, and C) 225 ppb
