Abstract Grapevine powdery mildew is caused by Erysiphe necator that seriously harms grape production in the world. Stilbene synthase makes phytoalexins contribute to resistance of grapevine against mildew. A novel VqNSTS3 was identified and cloned from Chinese wild Vitis quinquangularis accession Danfeng-2. Novel transferred into susceptible ‘Thompson Seedless’ Agrobacterium-mediated transform...

powdery mildew caused by erysiphe necator schw. is one of the most economically destructive diseases of grapevines all over the world including iran. in this experiment, the effects of powdery mildew on grape yield, sugar and tartaric acid contents of must quality were quantified for different grapes with 14 cultivars of grapes including shahani, kishmishi, rasmi, tokolgan, garashilig, seyrakpo...

Grapevine is one of the world’s most economically important fruit crops. It known that Vitis vinifera a host for large number pathogenic agents, which significantly reduce yield and berry quality. This forces agronomists to use huge amount fungicides. Over last few decades, alternative methods solving this problem have been developed continue be developed. Such new technologies as marker-assist...
