Project description:In this study we compare the transcriptome response of two potato varieties Atlantic and NY138 to the infection by Candidatus Liberibacter solanacearum. Four weeks old potato plant grown in growth chamber were infested with potato psyllid to transmit the pathogen Candidatus Liberibacter solanacearum. Three weeks after infestation leaf samples were collected for RNA extraction and transcriptome analysis. This is the first transcriptome study on this potato disease.

Project description:Time series response of potato cv. Désirée, which is tolerant to PVY infection, was analysed in both inoculated as well as upper non-inoculated leaves. Additionally, transgenic plants deficient in accumulation of salicylic acid (NahG- Désirée) were studied in the same setting.

Project description:Potato virus YNTN (PVYNTN), causing potato tuber ring necrosis disease, dramatically lowers the quantity and the quality of the potato yield all over the world. The cultivar Igor is one of the most susceptible cultivars, developing severe disease symptoms on plants as well as on tubers. Finding genes differentially expressed in the early response to infection, when the host response is more defense- than infection- related, could improve our understanding of the potato - PVYNTN interaction. Differential gene expression in early response of potato cv. Igor plants to PVYNTN infection was studied using potato TIGR cDNA-microarrays. Expression was compared between mock inoculated and virus infected plants 12 hours after inoculation, in four biological replicates. Keywords: direct comparison

Project description:Our aim was to investigate involvement of salicylic acid signalling in Ny-mediated hypersensistive response by comparison of transcriptomic response to the Potato Virus Y in potato plants of genotypes Rywal, bearing Ny-1 allele and NahG-Rywal, unable to accumulate salicylic acid in three time points (1, 3 and 6 days post inoculation) after viral inoculation.

Project description:Field-grown tubers of potato were examined for infection by Tobacco rattle virus and consequent production of corky ringspot or spraing symptoms. A microarray study identified tuber genes that are differentially expressed in response to TRV infection and to spraing production, showing that hypersensitive response (HR) pathways are activated in spraing-symptomatic tubers. This was confirmed by quantitative RT-PCR (Q-RT-PCR) of a selected group of HR-related genes and by histochemical staining of excised tuber tissue with spraing symptoms. Q-RT-PCR of TRV in different areas of the same tuber slice showed that non-symptomatic areas contained higher levels of virus than did spraing-symptomatic areas. This suggests that spraing formation is associated with an active plant defence that reduces the level of virus in the infected tuber. Expression of two plant defence genes was similarly upregulated in spraing-symptomatic tubers that were infected with another virus, Potato mop-top-virus, suggesting that spraing is a generalised response to virus infection of tubers.

Project description:Potato is one of the most important food crops for human consumption. The obligate biotrophic pathogen Spongospora subterranea infects potato roots and tubers, resulting in considerable loss of potato tuber yield and quality. A comprehensive understanding of how potato plants respond to S. subterranea infection is essential for the development of pathogen-resistant crops. Here we employed label-free proteomics and phosphoproteomics to quantify protein-level responses of the susceptible and resistant potato cultivars in response to S. subterranea. A total of 2669 proteins and 1498 phosphoproteins were quantified in the leaf samples of the different treatment groups. Following statistical analysis of the proteomic data, oxidoreductase activity, electron transfer, and photosynthesis were identified as significant processes that differentially changed upon infection specifically in the resistant cultivar and not in the susceptible cultivar. The phosphoproteomics results indicated increased activity of signal transduction and defence response functions in the resistant cultivar. In contrast, the majority of increased phosphoproteins in the susceptible cultivar were related to transporter activity and localisation. This study provides new insight into the molecular mechanisms involved in potato resistance to S. subterranea infection and has highlighted the critical roles of protein phosphorylation in the regulation of potato immune response.
