Antioxidant Gene Expression. The gene expression levels across the rows are hierarchically clustered. Magenta cells represent significant positive expression changes, blue cells represent significant negative changes, and off white cells represent no change or no statistically significant change. The level of significance used was at P ≤ 0.05. Genes and metabolites are grouped according to MapMan bin or MapMan bin combined with cellular location. The figure is divided into panels: A, thioredoxins transcripts associated with plastids, B, thioredoxins associated with the endoplasmic reticulum (ER), C, thioredoxins transcripts with unknown or locations other than plastids or endoplasmic reticulum, D, catalases and dismutases transcripts, E, glutaredoxin Transcripts, and F, ascorbate-related transcripts.
