Vitamin C Content in Fruits: Biosynthesis and Regulation

Determination of vitamin C in iranian citrus fruits

Carotenoid Biosynthesis and their Regulation in Citrus Fruits

Carotenoids are the main pigments responsible for the attractive color of the peel and pulp of citrus fruits and greatly contribute to their nutritional and antioxidant value. Fruits of different Citrus species display a broad array of color singularities and in many cultivars the peel and the pulp also exhibit different color, envisaging specieand tissuespecific regulation of the carotenoid co...

Vitamin C content and juice quality of exposed and shaded citrus fruits.

That the vitamin C (ascorbic acid) con tent of a fruit is dependent upon the in tensity of incident light was suggested by findings of Zilva and his associates (10) reported in 1935. These investigators found that the red peel of Bramley's Seedling apples contained twice as much vitamin C as the green peel. Although they did not mention light as a factor in the production of this difference in ...

New insights into the regulation of anthocyanin biosynthesis in fruits.

Anthocyanins are important health-promoting pigments that make a major contribution to the quality of fruits. The biosynthetic pathway leading to anthocyanins is well known and the key regulatory genes controlling the pathway have been isolated in many species. Recently, a considerable amount of new information has been gathered on the developmental and environmental regulation of anthocyanin b...

Regulation of L-ascorbic acid content in strawberry fruits

Plants have several L-ascorbic acid (AsA) biosynthetic pathways, but the contribution of each one to the synthesis of AsA varyies between different species, organs, and developmental stages. Strawberry (Fragaria×ananassa) fruits are rich in AsA. The pathway that uses D-galacturonate as the initial substrate is functional in ripe fruits, but the contribution of other pathways to AsA biosynthesis...
