Association of VvmybA1 Gene Expression with Anthocyanin Production in Grape (Vitis vinifera) Skin-color Mutants

A Candidate-Gene Association Study for Berry Colour and Anthocyanin Content in Vitis vinifera L.

Anthocyanin content is a trait of major interest in Vitis vinifera L. These compounds affect grape and wine quality, and have beneficial effects on human health. A candidate-gene approach was used to identify genetic variants associated with anthocyanin content in grape berries. A total of 445 polymorphisms were identified in 5 genes encoding transcription factors and 10 genes involved in eithe...

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...

Evolution and expression analysis of the grape (Vitis vinifera L.) WRKY gene family

WRKY proteins comprise a large family of transcription factors that play important roles in plant defence regulatory networks, including responses to various biotic and abiotic stresses. To date, no large-scale study of WRKY genes has been undertaken in grape (Vitis vinifera L.). In this study, a total of 59 putative grape WRKY genes (VvWRKY) were identified and renamed on the basis of their re...

Expression of related proteins and aquaporin genes in grape (Vitis vinifera L.) under salinity sress

Due to worldwide increasing of salinity, the identification of genes conferring tolerance to plants is important. The aim of this study was to investigate salinity effects on the expression of three genes-related to proteins and aquaporin in grape (Vitis vinifera L.). Based on screening study on 18 grape genotypes, H6 and Gharashani that showed lower decrease in water potential, leaf area, leaf...
