Figure 2

Hierarchical cluster of 907 selected genes from the μPeach1.0 microarray (A) and 2548 selected genes from the 15 K apple microarray (B). Each gene was scaled to 1 to represent maximum expression to allow cluster separation by expression pattern. The colours for each of the groupings were chosen to differentiate the groups and do not relate to the peach and apple groupings. The yellow to red scale to the right of each figure is a colour scale representing the expression level of each gene as it relates to the highest time point of expression. The intense red represents the maximum time of expression and the yellow represents the lowest per cent of that maximum expression. As the genes are different in each of the array platforms, these scales can not be compared between the platforms.
