Figure 2

Principal component analysis (PCA) plots generated with ggbiplot in R showing variation and clustering of samples in different groups. (A) PCA plot for samples at 2 dpi. (B) PCA plot for samples at 6 dpi. Horizontal and vertical axis show two principal components that respectively explain variation between different lines and that between different treatments. Sample clusters in different groups are circled with ellipses. Different groups are represented in different shapes and colors: Fayoumi (blue), Leghorn (red), NDV (triangle), Control (circle).
