The Vitis vinifera sugar transporter gene family: phylogenetic overview and macroarray expression profiling

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...

Ribozyme and Macroarray: Identification of AP-2-Regulated Genes by Macroarray Profiling of Gene Expression

Whole-Genome Survey of the Putative ATP-Binding Cassette Transporter Family Genes in Vitis vinifera

The ATP-binding cassette (ABC) protein superfamily constitutes one of the largest protein families known in plants. In this report, we performed a complete inventory of ABC protein genes in Vitis vinifera, the whole genome of which has been sequenced. By comparison with ABC protein members of Arabidopsis thaliana, we identified 135 putative ABC proteins with 1 or 2 NBDs in V. vinifera. Of these...

Molecular characterization and expression analysis of the Rop GTPase family in Vitis vinifera.

Rop/Rac GTPases are plant-specific signalling proteins with multiple roles, some of which have implications in plant development and in hormone signal transduction. Using expressed sequence tag (EST) and gene database analyses, members of the Rop family were characterized for the first time in a perennial species (Vitis vinifera). The grapevine genome was found to contain seven expressed VvRops...

Untargeted metabolic profiling of Vitis vinifera during fungal degradation.

This paper illustrates the application of an untargeted metabolic profiling analysis of winery-derived biomass degraded using four filamentous fungi (Trichoderma harzianum, Aspergillus niger, Penicillium chrysogenum and P. citrinum) and a yeast (Saccharomyces cerevisiae). Analysis of the metabolome resulted in the identification of 233 significant peak features [P < 0.05; fold change (FC) > 2 a...
