Figure 4
Validation of array data using quantitative PCR (qPCR). Gene abbreviations are shown below each graph. Corresponding pathway is indicated after each abbreviation as phenylpropanoid P , lignin L or flavonoid F . Y-axis represents Log2-fold change relative to values (>0) obtained from the 87 days after bloom (DAB) reference sample. X-axis is DAB. Some of the genes were present only in the peach array, some only in the apple array (4-coumarate CoA ligase) some in both (cinnamoyl CoA reductase) and some are represented by multiple oligos (chalcone synthase). Data from the qPCR is shown as solid lines, apple array data as dotted lines and peach array data as dashed lines.
