1.3.1.112 berry grape flowers have high levels of proanthocyanidins, and accumulation continues in skin and seeds from fruit set until the onset of ripening. ANR is expressed throughout early flower and berry development, with expression increasing after fertilization. During grape ripening, proanthocyanidin levels decrease in both skin and seeds, and expression of genes encoding ANR and LAR are no longer detected Vitis vinifera
