Venn diagram summary of differentially expressed genes identified in Chardonnay at three stages of ripening. Chardonnay whole bunches and densimetrically sorted berries were harvested at the 7-days before harvest (TH-7), theoretical harvest (TH) and 10-days after harvest (TH+10) stages during the 2005 and 2006 years. Comparisons of the expression profiles of TH versus TH-7 and TH+10 versus TH were made for whole bunches and densimetrically sorted berries. The total numbers of genes differentially expressed are indicated in respective circles (P < 0.05, ≥1.75-fold). The combined number of genes simultaneously up- or down-regulated is given in intersections between circles. Twelve genes were differentially expressed at all stages of late ripening; some genes were stage or sample type specific while others were overlapping in two stage or sample comparisons (for gene identity, see Tables 4, 5 and 6 and Additional files 1 and 2(Tables S1and S2)). WBB, whole bunch berries; DSB, densimetrically sorted berries.
