Project description:Potato genotypes from a diploid potato population were divided in two groups based on their response to Potato virus A (PVA). Plants exhibiting hypersensitive response were compared to plants exhibiting non-necrotic response (i.e. blocking virus movement without cell death).<br>The comparisons were made before inoculation and 12 and 24 hours post-inoculation.<br>

Project description:Potato virus YNTN (PVYNTN) is one of the most devastating potato virus causing great losses in the potato production industry. PVYNTN induces severe symptoms on inoculated leaves and a disease known as potato tuber necrosis ringspot disease (PTNRD) develops on tubers. Closely related PVYN isolate induces only mild symptoms on inoculated potato leaves and no symptoms on tubers. The early response of sensitive potato cvs. Igor and Nadine to inoculation with PVYNTN and PVYN was analysed allowing identification of genes involved in severe symptoms induction. Microarray and quantitative-PCR analysis was carried out to identify differentially expressed genes after inoculation with both virus isolates. Two distinct groups of genes were shown to have a role in severe symptoms development – one group of genes related to energy production and a second group of genes connected with virus spread. Earlier accumulation of sugars and decrease in photosynthesis was observed in leaves inoculated with aggressive PVYNTN isolate than in leaves inoculated with milder PVYN isolate. PVYNTN isolate was shown not to activate differential expression of antioxidant metabolism and pectinmethylesterase inhibitor (PMEI) leading to a delay in plant response and on the other hand it limited callose deposition enabling faster virus spread through the plant.

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:In the present study molecular interactions between potato plants, Colorado potato beetle (CPB) larvae and Potato virus YNTN (PVYNTN) were investigated by analyzing gene expression in potato leaves. mRNA samples of secondary PVYNTN-infected (CPB_PVY) and healthy potato plants (CPB_H) cultivar Igor and of RNAi coi1-silenced (CPB_coi1) and non-transformed (CPB_NT) potato plants cultivar Desiree collected 24 h post CPB infestation and respective control non-infested samples (CONT_PVY, CONT_H, CONT_coi1, CONT_NT).
