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 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: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. While cultivar Igor is one of the most susceptible cultivars, developing severe disease symptoms on plants as well as on tubers, cv. Sante is resistant and thus not affected by the virus. 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. Moreover, the differences in the response of the sensitive and resistant cultivar can pinpoint the genes involved in differential sensitivity of the cultivars. Differential gene expression in the early response of potato cvs. Igor and Sante to PVYNTN infection was studied using potato TIGR cDNA-microarrays. Expression was compared between mock inoculated and virus infected plants 0.5 and 12 hours after inoculation.

Project description:The use of phosphites in disease control management and abiotic stress has proven to be effective. Although the mechanisms underlying their effect remain unclear, it has been postulated that miRNAs could be involved. In order to understand these mechanisms we performed NGS sequencing in potato leaves treated or not with KPhi to identify miRNAs responsive to this biocompatible compound. The aim of the present work is to identify miRNAs that are involved in the regulation of potato defense responses after phosphite treatment.

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.
