SSR Genotyping of Wild Grape Species and Grape Cultivars of Vitis vinifera and V. vinifera ^|^times; V. labrusca

Polyphenolic Contents and Antioxidant Properties of Different Grape (V. vinifera, V. labrusca, and V. hybrid) Cultivars

The polyphenolic contents and the antioxidant activity of the skins and pulps of different grape cultivars were estimated using HPLC and DPPH antioxidant assay, respectively. The phenolics and flavonoids identified were quercetin, kaempferol, caffeic acid, p-coumaric acid, cinnamic acid, and (-)-epicatechin. The total phenolic contents were found to be the highest in the grape skin of Flouxa (>...

RAPD analysis of selected local Turkish grape cultivars (Vitis vinifera).

Turkey is very rich in local grape varieties. The solution to the problem of identifying local cultivars, which is considered an important deficiency for the region, will only be possible when they can be defined with molecular markers. Forty-nine local grapevine cultivars from Şanlıurfa (Turkey) were characterized with RAPD markers. Twenty-five decamer primers selected from 60 primers were use...

The Evolutionary Genomics of Grape (Vitis vinifera ssp. vinifera) Domestication

Evolutionary genomics of grape (Vitis vinifera ssp. vinifera) domestication

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

Occurrence and estimation of trans-resveratrol in one-year-old canes from seven major Chinese grape producing regions.

The concentration of trans-resveratrol in 165 grape cane samples from three major grape production regions and four large distribution centers of Chinese wild Vitis species were determined by reversed-phase high-performance liquid chromatography (HPLC). Among the different genotype groups and purpose of uses, cultivars of V. vinifera had much higher amounts of trans-resveratrol than did the cul...
