From: Profiling the venom gland transcriptomes of Costa Rican snakes by 454 pyrosequencing
Principal Component Analysis (PCA) of the Costa Rican snake venom gland transcriptomes (A, B) and the corresponding proteomes (C, D). Panels A and C show, respectively, the contributions to PC1 and PC2 of the different toxin families of the transcriptomes and the proteomes. Panels B and D, score plots displaying the segregation of the transcriptomes (B) and the proteomes (D) into different categories. In B, PC1 and PC2 contribute equally and together explain 65% of the observed transcriptome variability; in D, PC1 and PC2 explain 70% of the variability among proteomes.
