Analysis of proteins differentially accumulated in mature and ripe fruit. a All 1663 proteins detected in mature (O1) and ripe (O2) fruit were used to perform a Principal Component Analysis (PCA), with PC1 segregating mature from ripe fruit (A). From these 1663 proteins, 248 displayed a differential accumulation in O1 and O2 samples. b The main biological processes related to the differentially accumulated proteins in O1 fruit were associated to glycogen and isocitrate metabolism, and protein localization. c When assessing all the 1663 characterized proteins (“All_proteins”), no enrichment was found. Among the proteins upregulated in mature fruit, those with protein-coding genes in chromosome 3 (actual, black bars) were more than expected by chance (expected, grey bars, hypergeometric test, pvalue < 0.05). The same analysis determined that those protein-coding genes upregulated in ripe fruit were located, more than expected by chance, in chromosome 6 (pvalue < 0.01). Chr. - Chromosome
