geNorm ranking of reference genes over a grape berry development series. 2003 pericarp series (□) and 2004 pericarp series (). Ranked genes are shown in Table 2. Initially, expression stabilities (M) are calculated for each gene and the average M for all genes is plotted. Then the least stable gene is eliminated from the set and new M values are calculated in an iterative process until only two genes remain.
