Figure 3. Venn diagrams showing the number of differentially expressed genes in pairwise temperature comparisons as determine by the DESeq2 analyses (FDR=0.05) for the heat-tolerant B. calycifloruss.s. (A) and the heat-sensitive B. fernandoi (B). Blue color (C) represents control treatment, orange color (M) represents mild heat treatment, and red color (H) represents high heat treatment. Up- and down- regulation is defined from the perspective of the higher temperature over the lower one.
