Comparison of transcript expression profiles from 12 samples. A, Principal component analysis (PCA) of 12 samples; (B), Hierarchical clustering and correlation coefficient based on transcripts expression of each samples. Sample ID named following inbred line (B and I represented B73 and IL85 respectively) + treatment (CK and CD represented control and cold stress respectively) + replication
