Figure 2.

(A) Ranked expression correlation between two data sets samples. Each dot depicts a gene in common between data sets, where x and y axes represents ranked expression of genes in samples from R. serpentina and C. roseus datasets, respectively. (B) Principal component analysis (PCA) plot depict that all samples are clustered according to plant species inside the 2-dimensional space indicating clear differences in expression profiles. Red and green data points correspond to R. serpentina and C. roseus samples, respectively.
