Age-dependent differential transcriptomic responses to infection. a Principal component analysis (PCA) of 8 and 16 dpp inoculated fruit at 0, 4, 24, and 48 hpi. b Number of differentially expressed genes in each of three within-age consecutive contrasts: 4 vs. 0 hpi, 24 vs 4 hpi, and 48 vs 24 hpi. c-e Venn diagrams comparing all significantly differentially expressed (adjusted P < 0.05, fold change ≥2) genes in 8 and 16 dpp inoculated fruit at (c) 4 vs. 0 hpi, (d) 24 vs 4 hpi, and (e) 48 vs 24 hpi. Counts in red and blue denote up- and downregulated genes, respectively. Blue and red highlighted areas represent shared- and inverted-differential-expression, respectively
