New candidate genes for the fine regulation of the colour of grapes.

Costantini L, Malacarne G, Lorenzi S, Troggio M, Mattivi F, Moser C, Grando MS - J. Exp. Bot. (2015)

Bottom Line: To shed light on this issue, the grapes of 170 F1 progeny from the cross 'Syrah'×'Pinot Noir' were characterized at the mature stage for the content of 15 anthocyanins during four growing seasons.New information on some aspects which had scarcely been investigated so far, such as anthocyanin transport into the vacuole, or completely neglected, such as acylation, is provided.These genes represent a valuable resource in grapevine molecular-based breeding programmes to improve both fruit and wine quality and to tailor wine sensory properties according to consumer demand.

Linkage map of the Syrah×Pinot Noir cross. Distances of markers from the top (in cM) are indicated on the left side of linkage groups. Bars on the right correspond to 1–LOD confidence intervals of QTLs identified in at least two seasons (or to regions where significant markers were found with Kruskal–Wallis analysis). For each trait, the average phenotypic variance explained by the QTL and the number of years (in parentheses) in which significants QTLs (or markers) were detected are reported. The marked portion of the linkage group corresponds to the overall confidence interval used for gene prediction extraction. Cya, cyanidin; Peo, peonidin; Del, delphinidin; Pet, petunidin; Mal, malvidin; 3M, 3-monoglucoside; Ac, acetate; Cou, p-coumarate; Tot, total; Der, derivatives (3-monoglucoside+3-monoglucoside-acetate+3-monoglucoside-p-coumarate); 3ʹMeth/3ʹOH, peonidin 3-monoglucoside/cyanidin 3-monoglucoside; 3ʹ5ʹMeth/3ʹ5ʹOH, malvidin 3-monoglucoside/delphinidin 3-monoglucoside; diOH, di-hydroxylated (cyanidin+peonidin 3-monoglucoside); triOH, tri-hydroxylated (delphinidin+petunidin+malvidin 3-monoglucoside).

Cya, cyanidin; Peo, peonidin; Del, delphinidin; Pet, petunidin; Mal, malvidin; 3M, 3-monoglucoside; Ac, acetate; Cou, p-coumarate; Tot, total; Der, derivatives (3-monoglucoside+3-monoglucoside-acetate+3-monoglucoside-p-coumarate); 3ʹMeth/3ʹOH, peonidin 3-monoglucoside/cyanidin 3-monoglucoside; 3ʹ5ʹMeth/3ʹ5ʹOH, malvidin 3-monoglucoside/delphinidin 3-monoglucoside; diOH, di-hydroxylated (cyanidin+peonidin 3-monoglucoside); triOH, tri-hydroxylated (delphinidin+petunidin+malvidin 3-monoglucoside). (This figure is available in colour at JXB online.)

Mentions: Out of the 690 scored markers, 36 were discarded as they had too much missing data, they were identical to other loci, or their genetic position was inconsistent with the physical position. Out of the 654 remaining markers, 593 could be finally placed onto 19 LGs covering 1184 cM with an average distance between markers of 2 cM (Fig. 2; Supplementary Table S1 at JXB online). QTL analysis is expected to benefit from it, as high-density maps were recently demonstrated to improve the precision of QTL localization and effect estimation, especially for minor QTLs, as well as the power to resolve closely linked QTLs (Stange et al., 2013).
