Fig. 1From: Characterization of the transcriptional divergence between the subspecies of cultivated rice (Oryza sativa)Principle component analysis of markers and gene expression matrices. The top four principle components from PCA analysis of the genotypic data are pictured in A and B to illustrate the divergence of the major subpopulations in rice. The panels in C and D summarize PCA of expression data. PVE: percent variation explained by each componentBack to article page
