Figure 2From: A newly-developed community microarray resource for transcriptome profiling in Brassica species enables the confirmation of Brassica-specific expressed sequencesPrincipal Component Analysis of gene expression in the four genotypes. Microarray datasets for each of the individual samples subjected to analysis by three principal components. The proportions of the total variation explained by principal components 1, 2 and 3 are 22.1%, 13.6% and 10.1%, respectively.Back to article page
