“…Applications of laminarin to grapevine plants reduced infection by Botrytis cinerea Pers (grey mold disease) and P. viticola in leaves by approximately 55 and 85 %. However, the application of inhibitors of LOX gene and callose synthesis reduced the effectiveness of laminarin up to 80 %, suggesting that its effect principally relies on the JA pathway (Trouvelot et al, 2008).…”

The activation of defensive responses of plants is a promising tool for controlling pests in conventional agriculture. Over the last few years, several compounds have been studied to protect crops from pests, without displaying direct toxicity for pathogenic organisms. These compounds have the ability to induce a priming state on the plants that results in resistance (or tolerance) against subsequent infection by a pathogen. In terms of molecular response, induced plant defense involves a broad number of physical and biochemical changes such as callose deposition or phenolic compounds, activation of salicylic and/or jasmonic acid pathways or synthesis of defense-related enzymes. Despite the large number of studies performed to ascertain the physiological and biochemical basis of induced resistance, only a few resistance-activating compounds have been studied as a real alternative to classic means of control and the studies geared towards incorporating induced resistance into disease management programs are relatively rare. The incorporation of natural resistance inducer in pest management programs of woody crops, alone or in combination with classical methods, could be a reliable method for reducing the amount of chemical residues in the environment. In this review, we discuss the current knowledge of induced resistance in woody crops, focusing on the mode of action of compounds authorized for conventional agriculture. We conclude by discussing the environmental and economic advantages of applying resistance inducers to conventional agriculture with special emphasis on natural compounds.

“…Although a number of studies describe the biology of the infection process of grapevine by P. viticola (Allegre et al 2007;Kortekamp 2005;Musetti et al 2007;Unger et al 2007;Werner et al 2002) and the characterisation of defence reactions in susceptible and resistant grapevines (Dai et al 1995;Gindro et al 2003;Kortekamp 2006, Kortekamp andZyprian 2003) or their response to inducers of defence reactions (Aziz et al 2003;Hamiduzzaman et al 2005;Trouvelot et al 2008), a large-scale analysis of P. viticola and grapevine interaction has not been reported.…”

Identification of genes expressed during the compatible interaction of grapevine with Plasmopara viticola through suppression subtractive hybridization (SSH)

et al. 2010

Grapevine (Vitis vinifera) is the most widely cultivated and economically important fruit crop, but is susceptible to a large number of diseases. Downy mildew, caused by the obligate biotrophic oomycete pathogen Plasmopara viticola, is a common disease present in all regions where vines are cultivated. We used suppression subtractive hybridization (SSH) to generate two cDNA libraries enriched for transcripts induced and repressed, respectively, in the susceptible grapevine cultivar Chasselas 24 h after inoculation with P. viticola. Differential screening on glass slide microarrays yielded over 800 putative genes that were upregulated in response to P. viticola infection and over 200 that were down-regulated. One hundred and ninety four of these, were sequenced, identified and functionally categorised. Transcript abundance of twelve genes over a 48 h time course was examined by reverse transcriptase quantitative real-time PCR (RT-qPCR). Ten of these genes were induced/enhanced by P. viticola challenge, confirming the results of the SSH. The vast majority of the genes identified are related to defence. Interestingly, many genes involved in photosynthesis were down-regulated.

“…To our knowledge, causal relationships between ROS and cell death and between cell death and plant defence against pathogens remain an issue with broad importance. In both plants under infection by pathogens (Jabs et al, 1996;Tanaka et al, 2003) or those treated with different elicitors (Desikan et al, 1998;Peng et al, 2003;Peng et al, 2004;Tanaka et al, 2003;Trouvelot et al, 2008), ROS production is either dispensable for the induction of cell death and indispensable for the defence response. This is true for elicitins based on published studies.…”

suggesting the importance of H 2 O 2 in the pathway of HCD signal transduction from the trichomes to mesophylls. This pathway was no longer activated when leaf trichomes were treated with C51S, a ParA1 mutant protein defective in its interaction with N. tabacum TTG1 (NtTTG1), which is a trichome protein that binds ParA1, rather than C51S, in vitro and in trichome cells. The ParA1-NtTTG1 interaction and the HCD pathway were also abrogated when NtTTG1 was silenced in the trichomes. These observations suggest that NtTTG1 plays an essential role in HCD signal transduction from leaf trichomes to mesophylls. Supplementary material available online at
