Normalized abundance of specific proteins during grape berry development. GDP-D-mannose-3,5epimerase (GME, uniprot ID:F6THR3) during 2011 (a) and 2013 (b); L-galactose-1-phosphate phosphatase (VTC4, uniprot ID: E0CNP0) during 2011 (c) and 2013 (d); L-galactose dehydrogenase (L-GalDH, uniprot ID: D7T3I7) during 2011 (e) and 2013 (f); L-idonate dehydrogenase (L-IdnDH, uniprot ID: Q1PSI9) during 2011 (g) and 2013 (h). Error bars are standard errors of three biological replicates (LabelFree analysis). The developmental stage of veraison is indicated by a grey dotted box. (*: significant difference in Friedman test (α = 0.05)). FB: flowering beginning; PS: pea-sized; BC: bunch closure (berries touching); VB: veraison beginning (10 % ripe berries); VE: verasion end (80 % ripe berries); H: harvest (maturity); GME: GDP-D-mannose-3, 5 epimerase; VTC4: L-galactose-1-phosphate dehydrogenase; L-GalDH: L-Galactose dehydrogenase; L-IdnDH: L-Idonate dehydrogenase
