Comparative microarray (Vitis GeneChip) analysis in young leaves revealed considerable variation in gene expression between Vitis vinifera L. and Vitis aestivalis Michx. Approximately 12% of the genes were differentially expressed in the two grapevine species (P < 0.001). Over 200 probe sets were identified which consistently detected transcripts in one(More)
Tissue colonization by grape powdery mildew (PM) pathogen Erysiphe necator (Schw.) Burr triggers a major remodeling of the transcriptome in the susceptible grapevine Vitis vinifera L. While changes in the expression of many genes bear the signature of salicylic acid (SA) mediated regulation, the breadth of PM-induced changes suggests the involvement of(More)
