TranscriptomicsPotato virus Y infection hinders potato defence response and renders plants more vulnerable to Colorado potato beetle attack
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 a...

MetabolomicsComparative Metabolomic Profiling of Compatible and Incompatible Interactions Between Potato and Phytophthora infestans

Late blight is one of the main biological stresses limiting the potato yield; however, the biochemical mechanisms underlying the infection process of Phytophthora infestans remain unrevealed. In this study, the late blight-resistant potato cultivar Ziyun No.1 (R) and the susceptible cult...

TranscriptomicsMicroarray transcription profiling of healthy and PVYNTN infected potato tuber tissues (necrotic and non-necrotic)
To extend our understanding of systemic necrosis in susceptible potato tubers infected with the necrotic strain of Potato virus Y (PVYNTN) gene expression was compared between healthy and infected non-necrotic and necrotic (both non-necrotic and necrotic tissue) potato tubers.

TranscriptomicsTranscription profiling of potato genotypes hypersensitive vs non-hypersensitive to potato virus A upon infection with the virus
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).
The comparisons were ...

TranscriptomicsPVY-NTN elicits diverse gene expression response in different potato genotypes in the first 12 hours after inoculation
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 ...

ProteomicsMOA:Multiomics analysis of potato response to Potato virus Y (PVY) infection
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.

TranscriptomicsComparative transcript profiling of plant virus synergism
Many virus diseases of economic importance to agriculture result from mixtures of different pathogens invading the host at a given time. This contrasts with the relatively scarce studies available on the molecular events associated with virus-host interactions in mixed infections. In comparison to s...

TranscriptomicsComparative genomic hybridization of two suppression subtractive hybridization cDNA libraries one enriched with cDNAs from Potato virus A (PVA) resistant potato genotypes 24h post-inoculation and the other from PVA-susceptible potato genotypes 24h post-inoculation
A comparison between two suppression subtractive hybridization cDNA libraries. One library is enriched with cDNAs from Potato virus A (PVA) resistant potato genotypes (non-necrotic resistance, nnr) 24h post-inoculation and the other library from PVA-susceptible potato 24h post-inoculation.

TranscriptomicsIdentification and characterization of miRNAome in root, stem, leaf and tuber developmental stages of potato (Solanum tuberosum L.) by high-throughput sequencing
Purpose: MicroRNAs (miRNAs) are ubiquitous components of endogenous plant transcriptome. miRNAs are small, single-stranded and ~21 nt long RNAs which regulate gene expression at the post-transcriptional level and are known to play essential roles in various aspects of plant development and growth. P...

TranscriptomicsAnalysis of transcriptional response to mutated Potyvirus Potato virus A that induces necrotic symptoms.
Mutations introduced to a highly variable region in HCpro reduced HCpro-HIP2 interactions and virulence of PVA, and induced novel types of necrotic symptoms in the systemically infected leaves of Nicotiana species. Microarray-based analysis of gene expression revealed induction of large numbers of d...
