Grapevine comparative early transcriptome profiling reveals that Flavescence dorée phytoplasma represses plant responses induced by vector feeding in susceptible varieties

Project description:Flavescence dorée is the most serious grapevine yellows disease in Europe. It is caused by phytoplasmas which are transmitted from grapevine to grapevine by the leafhopper Scaphoideus titanus. Differences in susceptibility among grapevine varieties suggest the existence of specific genetic features associated with resistance to the phytoplasma and/or possibly with its vector. In this work, RNA-Seq was used to compare early transcriptional changes occurring during the three-trophic interaction between the phytoplasma, its vector and the grapevine, represented by two different cultivars, one very susceptible to the disease and the other scarcely susceptible.

In this work, RNA-Seq was used to compare early transcriptional changes occurring during the three-trophic interaction between the phytoplasma, its vector and the grapevine, represented by two different cultivars, one very susceptible to the disease and the other scarcely susceptible. The comparison of the transcriptomic responses highlighted both passive and active defense mechanisms against the vector and/or the pathogen in the scarcely-susceptible variety, as well as the capacity of the phytoplasmas to repress the defense reaction against the insect in the susceptible variety.

'Bois noir' phytoplasma induces significant reprogramming of the leaf transcriptome in the field grown grapevine

Project description:Transcriptional profiling of Vitis vinifera cv. Chardonnay healthy vs. Phytoplasma-infected plants (Bois noir phytoplasma). Study was conducted on grapevine plants grown in the same vineyard (leaf midribs were sampled). Keywords: disease state analysis Two-condition experiment: healthy vs. infected plants/shoots. Biological replicates: 4 healthy, 4 infected. No replicates. Each sample was prepared as a pool of several samples (each sample was collected from a different shoots/plants) of the same disease status. Each sample was co-hybridized to a common reference cRNA (pool of all samples).

A microarray analysis highlights the role of tetrapyrrole pathways in grapevine responses to stolbur phytoplasma, phloem virus infections and recovered status

Project description:Several systemic diseases affect Vitis vinifera worldwide with important consequent management costs. Phytoplasma and viruses represent the most detrimental pathogens inducing symptoms and metabolic alterations that modify quantitatively the crop production. In the aim to investigate the plant/pathogen interactions, different grapevine samples, naturally affected (in mixed or single infections) by Stolbur phytoplasma (agent of Bois Noir disease) and viruses, in comparison to healthy and recovered controls, to identify the plant response to systemic pathogen infection. The preliminary results showed that expression levels of thousands of genes were altered in infected plants, involving various metabolic pathways.

A knockdown gene approach identifies an insect vector membrane protein with Leucin Rich Repeats as one of the receptors for the VmpA adhesin of flavescence dorée phytoplasma

Project description:The adhesion of flavescence dorée phytoplasma to the midgut epithelium cells of their insect vectors is partially mediated by the Variable Membrane Protein A (VmpA), an adhesin which shows lectin properties. In order to identify the insect receptor for VmpA, we lokked for Euscelidius variegatus cells proteins interacting with recombinant VmpA-His6 by mass spectrometry analysis of VmpA-E. variegatus protein complexes formed upon in vitro interaction assays.
