Separation of Arabidopsis genotypes from gene expression profiles. PCA score plot showing the complete dataset obtained from the transcriptomics analyses using DNA microarrays of rosette leaves of plants grown in the field of oePsbS (oe), wild-type (wt) and npq4 (4) Arabidopsis genotypes. The first two components from the PCA analysis is shown, 1 and 2 denote the two replicates of each genotype, each replicate containing RNA from a pool of plant individuals.
