(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) Study of gene expression during Plasmopara viticola infection in the resistant Vitis vinifera cultivar 'Regent'. The oomycete fungus Plasmopara viticola (Berk. et Curt.) Berl. et de Toni is responsible for grapevine downy mildew disease. Most of the cultivated grapevines are sensitive to this pathogen, thus requiring intensive fungicide treatments. The molecular basis of resistance to this pathogen is poorly understood. more...

(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) European grapevine cultivars (Vitis vinifera spp.) are highly susceptible to the downy mildew pathogen Plasmopara viticola. Breeding of resistant V. vinifera cultivars is a promising strategy to reduce the impact of disease management. Most cultivars that have been bred for resistance to downy mildew, rely on resistance mediated by the Rpv3 (Resistance to P. viticola) locus. However, despite the extensive use of this locus, little is known about the mechanism of Rpv3-mediated resistance. 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...

(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 biotrophic oomycete Plasmopara viticola, is one of the most economically significant grapevine diseases worldwide. Current strategies to cope with this threat rely on the massive use of phytochemical compounds during each cultivation season. The economic costs and negative environmental impact associated with these applications increased the urge to search for alternative strategies for sustainable disease control. more...

(Submitter supplied) Purpose: Lasiodiplodia theobromae is a pathogenic fungus causing Botryosphaeria dieback in grapevine. Heat and drought stress was suggested to promote the disease incidence in recent years, therefore we decided to evaluate the effect of heat on in vitro experiment, adding grapevine wood to simulate the environment in the trunk during in field infection. Methods: Fungal mRNA was extracted from mycellium collected after 49 hours of growth without stress in the presence of GW (GW_noHS) or in its absence (VS_noHS). more...

(Submitter supplied) The first genome-wide transcriptomic atlas of grapevine (Vitis vinifera) is based on 54 diverse samples expressing ~93% of predicted grapevine genes. Pollen and senescent leaves have unique transcriptomes but microarray analysis grouped all other samples into vegetative/green or mature/woody categories based on maturity rather than organ identity. This fundamental transcriptome reprograming during maturation was highlighted by three distinct statistical approaches supported by gene coexpression analysis. more...

(Submitter supplied) MicroRNAs are short (~21 base) single stranded RNAs that, in plants, are generally coded by specific genes and cleaved specifically from hairpin precursors. MicroRNAs are critical for the regulation of multiple developmental, stress related and other physiological processes in plants. Their action is generally mediated through complementary interactions with mRNA molecules - leading to their degradation or sequestration from the translational apparatus. more...

Cold can trigger adaptive process or lead to alterations in physiological traits when stress intensity exceeds a certain threshold. Grapevine flower development and fruit set are influenced by cold nights in the vineyard. The correct formation of sexual organs and the success of reproduction are dependent upon sugar supply which can be affected by low temperatures. more...

(Submitter supplied) Grape powdery mildew (PM), caused by the biotrophic ascomycete Erysiphe necator, is a devastating fungal disease that affects most Vitis vinifera cultivars. We have previously identified a panel of V. vinifera accessions from Central Asia with partial resistance to PM that possess a Ren1-like local haplotype. In this study we show that in addition to the typical Ren1-associated late post-penetration resistance, these accessions display a range of different levels of disease development suggesting that alternative alleles or additional genes contribute to determining the outcome of the interaction with the pathogen. more...
