Principle component analysis. Samples from the same experimental conditions tend to cluster together according to their gene expression profiles. The first principle component (PC1) appears to capture the differences of the gene expression profiles across the three experimental conditions (log-phase, T = 0 and T = 4), and the second component appears to capture the differences of the gene expression profiles among H37RV and MKR superspreader.
