comparison between proteome and transcriptome response in potato (solanum tuberosum l.) leaves following potato virus y (pvy) infection.	plant diseases caused by viral infection are affecting all major crops. being an obligate intracellular organisms, chemical control of these pathogens is so far not applied in the field except to control the insect vectors of the viruses. understanding of molecular responses of plant immunity is therefore economically important, guiding the enforcement of crop resistance. to disentangle complex regulatory mechanisms of the plant immune responses, understanding system as a whole is a must. howeve ...	2017	28684682
integrated analysis of tobacco mirna and mrna expression profiles under pvy infection provids insight into tobacco-pvy interactions.	potato virus y (pvy) is a globally and economically important pathogen of potato, tobacco, tomato and other staple crops and caused significant yield losses and reductions in quality.to explore the molecular pvy-host interactions, we analysed changes in the mirna and mrna profiles of tobacco in response to pvy infection. a total of 81 differentially expressed mirnas belonging to 29 families and 8133 mrnas were identified. the gene ontology (go) enrichment analyses showed that genes encoding the ...	2017	28687775
validation of reference genes for quantifying changes in gene expression in virus-infected tobacco.	to facilitate quantification of gene expression changes in virus-infected tobacco plants, eight housekeeping genes were evaluated for their stability of expression during infection by one of three systemically-infecting viruses (cucumber mosaic virus, potato virus x, potato virus y) or a hypersensitive-response-inducing virus (tobacco mosaic virus; tmv) limited to the inoculated leaf. five reference-gene validation programs were used to establish the order of the most stable genes for the system ...	2017	28689086
quantitative trait loci in pepper control the effective population size of two rna viruses at inoculation.	infection of plants by viruses is a complex process involving several steps: inoculation into plant cells, replication in inoculated cells and plant colonization. the success of the different steps depends, in part, on the viral effective population size (ne), defined as the number of individuals passing their genes to the next generation. during infection, the virus population will undergo bottlenecks, leading to drastic reductions in ne and, potentially, to the loss of the fittest variants. th ...	2017	28691663
the effects of potato virus y-derived virus small interfering rnas of three biologically distinct strains on potato (solanum tuberosum) transcriptome.	potato virus y (pvy) is one of the most economically important pathogen of potato that is present as biologically distinct strains. the virus-derived small interfering rnas (vsirnas) from potato cv. russet burbank individually infected with pvy-n, pvy-ntn and pvy-o strains were recently characterized. plant defense rna-silencing mechanisms deployed against viruses produce vsirnas to degrade homologous viral transcripts. based on sequence complementarity, the vsirnas can potentially degrade host ...	2017	28716126
silencing the tobacco gene for rna-dependent rna polymerase 1 and infection by potato virus y cause remodeling of cellular organelles.	rna-dependent rna polymerase 1 (rdr1) has been shown to be involved in dna methylation, rna silencing and regulating expression of other genes. rdr1 gene expression is stimulated by infection with potato virus y° (pvy). transgenic nicotiana tabacum plants silenced for rdr1 gene expression showed morphological changes in mesophyll cells, associated with remodeling of the nuclei, chloroplasts and mitochondria. rdr1 silencing led to decreased nuclear size, increased heterochromatin content and aggr ...	2017	28719835
breeding of a new potato variety 'nagasaki kogane' with high eating quality, high carotenoid content, and resistance to diseases and pests.	'nagasaki kogane' is a new potato variety bred from a cross between 'saikai 35' as a female parent and 'saikai 33' as a male. 'saikai 35' is resistant to bacterial wilt, contains the h1 and rychc genes for resistance to the potato cyst nematode (pcn) and potato virus y (pvy), respectively, and has high carotenoid content, while 'saikai 33' has large and high-yielding tubers and is resistant to both bacterial wilt and pcn. the carotenoid content of 'nagasaki kogane' is higher than that of 'dejima ...	2017	28744186
a novel recombined potato virus y isolate in china.	this study reports the findings of a distinct potato virus y (pvy) isolate found in northeast china. one hundred and ten samples (leaves and tubers) were collected from potato plants showing mosaic symptoms around the city of harbin in heilongjiang province of china. the collected tubers were planted and let to grow in a greenhouse. new potato plants generated from these tubers showed similar symptoms, except for one plant. subsequent serological analyses revealed pvy as the causing agent of the ...	2017	28811755
