Gene expression analyses after post-harvest treatments and in fruit from different cultivars. Four genes (cob, endoPG, CCR, and rab11) whose expression levels were decreased in woolly fruit, according to the macroarray data, were assayed by qPCR using cDNAs from different post-harvest treatments and cultivars. For peaches cv. O'Henry (O), the following samples were analysed: (c1) ripened and juicy fruit; (c2) cold-stored, non-ripened fruit; and (c3) cold-stored, ripened, and woolly. For peaches cv. Elegant Lady (E) and cv. Flamekist (F), samples from: (c1) ripened and juicy fruit and (c3) cold-stored, ripened, and woolly fruit were assayed. For each gene, the relative abundance of mRNA was normalized towards tubulin in the corresponding samples. The results are presented as a percentage of the highest value of relative abundance. Different letters between each treatment represent significant differences at P < 0.05 by LSD test.
