During the last decade, many berry-type fruits have been recognised as good sources of anthocyanins. Nevertheless, the use of anthocyanins in the development of food colourants and healthy and/or functional ingredients has been limited because of their low stability under given environmental conditions and interaction with other compounds in the food matrix. This review compiles information abo...

Changes in anthocyanin and endogenous abscisic acid (ABA) contents the berry skins of Vitis labruscana × V. vinifera cultivars, ‘Aki Queen’, ‘Ruby Roman’ were investigated during fruit development period. Color Queen’ berries mainly occurred within 20 days post véraison, while that was prolonged for about 40 days. In both ABA level skin started to increase a few before véraison; however, accumu...

Anthocyanin colors and factors which stabilize and enhance these labile pigments were studied in this thesis. Berry anthocyanin colors were successfully improved by phenolic acid and natural plant extract addition. The results obtained contribute to the understanding of the chemical behavior of anthocyanins. The color quality of black currant wine was improved by the addition of crowberry juice...

The diversity of pigmentation patterns observed in plants occurs due to the spatial distribution and accumulation of colored compounds, which may also be associated with structural changes to the tissue. Anthocyanins are flavonoids that provide red/purple/blue coloration to plants, often forming complex patterns such as spots, stripes, and vein-associated pigmentation, particularly in flowers. ...

The phytochemical constituents which comprise many edible berry fruits have increasingly been linked to modulation of biomarkers associated with conditions of diabetes, overweight/obesity, and cardiovascular disease (CVD), all components of metabolic syndrome. While many wild berries have long been valued in traditional medicine as health protective, it is only recently that the ability of berr...

Anthocyanins are major pigments in plants. Methylation plays a role in the diversity and stability of anthocyanins. However, the contribution of anthocyanin methylation to flower coloration is still unclear. We identified two homologous anthocyanin O-methyltransferase (AOMT) genes from purple-flowered (PsAOMT) and red-flowered (PtAOMT) Paeonia plants, and we performed functional analyses of the...

MdMYB1 is a crucial regulator of light-induced anthocyanin biosynthesis and fruit coloration in apple (Malus domestica). In this study, it was found that MdMYB1 protein accumulated in the light but degraded via a ubiquitin-dependent pathway in the dark. Subsequently, the MdCOP1-1 and MdCOP1-2 genes were isolated from apple fruit peel and were functionally characterized in the Arabidopsis (Arabi...
