Ingia / Ingia

Certain potato cultivars are capable of producing anthocyanin pigments in the potato skin and flesh and those pigments have been shown, together with other phytochemicals, to promote good health. Six common anthocyanidins (cyanidin, delphinidin, petunidin, pelargonidin, malvidin and peonidin) were

Ingia / Ingia

Efficient selection of potato varieties with enhanced nutritional quality requires simple, rapid, accurate, and cost-effective assays to obtain tuber chemical composition information. Our objective was to develop simple protocols to determine phenolics, anthocyanins, and antioxidant capacity in

A fluorogenic 5' nuclease (TaqMan) assay to assess dosage of a marker tightly linked to red skin color in autotetraploid potato.

We have recently identified an allele of dihydroflavonol 4-reductase ( dfr) that cosegregates with the ability of potato ( Solanum tuberosum L) to produce red pelargonidin-based anthocyanin pigments. A rapid assay to assess dosage of this allele in cultivated potato, an autotetraploid, would be

An allele of dihydroflavonol 4-reductase associated with the ability to produce red anthocyanin pigments in potato (Solanum tuberosum L.).

The potato R locus is necessary for the production of red pelargonidin-based anthocyanin pigments in any tissue of the plant, including tuber skin and flower petals. The production of pelargonidins in plants requires the activity of dihydroflavonol 4-reductase (DFR) to catalyze the reduction of

Ectopic expression of anthocyanin 5-o-glucosyltransferase in potato tuber causes increased resistance to bacteria.

The principal goal of this paper was to investigate the significance of anthocyanin 5-O-glucosyltransferase (5-UGT) for potato tuber metabolism. The ectopic expression of a 5-UGT cDNA in the tuber improved the plant's defense against pathogen infection. The resistance of transgenic lines against

Probing anthocyanin profiles in purple sweet potato cell line (Ipomoea batatas L. Cv. Ayamurasaki) by high-performance liquid chromatography and electrospray ionization tandem mass spectrometry.

A purple line cell line (PL) generated from the storage root of purple-fleshed sweet potato (Ipomoea batatas L.) cv. Ayamurasaki produces a complex mixture of anthocyanins, and seven major anthocyanins have been isolated and identified to date. All these anthocyanins are exclusively cyanidin or

The potato R locus codes for dihydroflavonol 4-reductase.

Ingia / Ingia

The potato R locus is required for the production of red pelargonidin-based anthocyanin pigments in potato (Solanum tuberosum L.). Red color also requires tissue-specific regulatory genes, such as D (for expression in tuber skin) and F (expression in flowers). A related locus, P, is required for

Inhibition of α-glucosidase, α-amylase, and aldose reductase by potato polyphenolic compounds.
