Expression of duplicate F3'5'H s in berry skin of four cultivars across eight developmental stages. Transcript levels are normalised to the expression of Ubiquitin. Bars indicate standard error of three biological replicates. Stacked panels share the same x-axis, reported below the bottom panel. The panel at the bottom right-hand corner reports significant differences between relative abundance of copy-specific transcripts across all developmental stages, within each cultivar. Colour scale from red to yellow indicates decreasing levels of gene expression, separated by a Student-Newman-Keuls test. Different letters indicate significant differences (P < 0.05).
