(Submitter supplied) Vitis vinifera berries are sensitive towards infection by the necrothopic pathogen Botrytis cinerea leading to important economic losses worldwide. The combined analysis of the transcriptome and metabolome associated with the infection has not been previously performed in grapes or in another fleshy fruit. In an attempt to identify the molecular and metabolic mechanisms associated with the infection, pepper- corn size fruits (EL 29) were infected in-field and green berries (EL 33) and veraison berries (EL 35) were collected for microarray analysis complemented with metabolic profiling using GC-EI-TOF/MS and headspace GC-EI-MS platforms. more...

(Submitter supplied) Two long serial analysis of gene expression (LongSAGE) libraries of germinating conidia of Botrytis cinerea were generated with and without resveratrol treatments for unraveling the antifungal mechanisms of this phytoalexin by global transcriptome analysis – 82,786 total tags and a minimum of 15,665 unitags were obtained respectively. By tag-to-gene mapping, about 55% of the total unitags were matched to known genes. more...

(Submitter supplied) We report the use of a Dual RNA-Seq approach to investigate the interaction of grapevine with the Botryosphaeria dieback agent L. theobromae. The aim of this work was to (1) identify pathogenicity factors produced by L. theobromae, and (2) determine the V. vinifera defence response to the pathogen.

(Submitter supplied) Downy mildew, caused by the oomycete Plasmopara viticola, is a serious disease in Vitis vinifera, the most commonly cultivated grapevine species. Several wild Vitis species have instead shown resistance to this pathogen and they have been used as a source to introgress resistance into a V. vinifera background. Stilbenoids represent the major phytoalexins in grapevine, and their toxicity has been strictly related to the specific compound. more...

(Submitter supplied) Background: The complex and dynamic changes during grape berry development have been studied in Vitis vinifera, but little is known about these processes in other Vitis species. The grape variety ‘Norton’, with a major portion of its genome derived from Vitis aestivalis, maintains high levels of malic acid and phenolic acids in the ripening berries in comparison with V. vinifera varieties such as Cabernet Sauvignon. more...

(Submitter supplied) Noble rot results from atypical infections of ripe grape berries by Botrytis cinerea. Unlike bunch rot, noble rot promotes favorable changes in grape berries and accumulation of secondary metabolites that enhance wine grape quality. Noble rot-infected berries of Sémillon, a white-skinned variety, were collected over three years from a commercial vineyard at the same time fruit were harvested for botrytized wine production. more...

(Submitter supplied) To understand the fruit changes and mechanisms involved in the compatible grapevine-virus interaction, we analyzed the berry transcriptome in two stages of development (veraison and ripening) in the red wine cultivar Cabernet Sauvignon infected with Grapevine leaf-roll-associated virus-3 (GLRaV-3). Analysis of global gene expression patterns indicate incomplete berry maturation in infected berries as compared to uninfected fruit suggesting viral infection interrupts the normal berry maturation process. more...

(Submitter supplied) Plasmopara viticola (Berk. and Curt.) Berl. and de Toni is the agent of the destructive disease known as grapevine downy mildew, for the control of which intensive fungicide treatments are required. Natural sources of resistance are available in several wild Vitis species, which are being used in traditional breeding approaches. However, molecular switches, signals and effectors involved in resistance are poorly understood. more...

(Submitter supplied) Cultivated grapevine (Vitis vinifera) is susceptible to many pathogens which cause significant losses to viticulture worldwide. Chemical control is available, but agro-ecological concerns have raised interest in alternative methods, especially in elicitation of plant immunity by bio-molecules such as Pathogen Associated Molecular Patterns (PAMPs). We have demonstrated that the beta-glucan laminarin (Lam) and its sulfated derivative (PS3) induce a PAMP-triggered immunity in grapevine against downy mildew (Plasmopara viticola). more...

The action of 13-LOX on linolenic acid enables production of 12-oxo-phytodienoic acid (12-OPDA) and its downstream products, termed jasmonates. As signals, jasmonates have related yet distinct roles in the regulation of plant resistance against insect and pathogen attack. more...
