Figure 3From: Transcriptome profiling of the feeding-to-fasting transition in chicken liverPrincipal Component Analysis (PCA) of the gene selection. The gene variables for the PCA were scaled to give them the same importance. A: individual factor map; B: gene factor map, only the genes highly correlated to the first two components are indicated (r > 0.7). The gene color was determined according to their HCA cluster (cl.i = cluster i).Back to article page
