Evaluation of reference genes for quantitative reverse-transcription polymerase chain reaction normalization in infected tomato plants.
Examination of expression variations of a set of eight candidate reference genes in tomato leaf and root tissues subjected to the infection of five taxonomically and molecularly different plant viruses and a viroid showed that different viral infections and tissues of origin influenced, to some extent, the expression levels of these genes.
Infection Cycle of Artichoke Italian Latent Virus in Tobacco Plants: Meristem Invasion and Recovery from Disease Symptoms
It is suggested that AILV-V entrance in SAM and activation of RNA silencing may be distinct processes since the latter is triggered in fully expanded leaves by the accumulation of viral RNA above a threshold level rather than by virus entrance inSAM.
Synergies and antagonisms in virus interactions.
Characterization of the interactions between Cucumber mosaic virus and Potato virus Y in mixed infections in tomato.
Mixed infection with the SON41 strain of Potato virus Y (PVY-SON41) in tomato increased accumulation of RNAs of strains Fny and LS of Cucumber mosaic virus (CMV-Fny and CMV-LS, respectively) and
Clinico-pathological characterization of hepatitis C virus-related B-cell non-Hodgkin's lymphomas without symptomatic cryoglobulinemia.
The findings strengthen the pathogenetic link between HCV and B-NHL and show that HCV infection may be associated with the malignant proliferation of defined B- cell subsets other than the immunoglobulin Mk B-cell subset involved in the pathogenesis of mixed cryoglobulinemia type II and associated lymphoplasmacytoid lymphoma type.
Differential effects of mild and severe Cucumber mosaic virus strains in the perturbation of MicroRNA-regulated gene expression in tomato map to the 3' sequence of RNA 2.
Some of the aspects of miRNA pathway perturbation described were peculiar to CMV-tomato interactions and involved in the etiology of the disease phenotype elicited in this host.
Production and fingerprinting of virus-free clones in a reflowering globe artichoke
Results demonstrates that AFLP-based molecular fingerprinting enables to verify the true to clone correspondence in nurseries, ensure the effective correspondence between the real and the declared identity of a clone, so that to avoid commercial frauds, and might represents a valuable tool for assessing somaclonal variation occuring during ‘in vitro’ propagation.
Viruses in artichoke.
Biological and molecular characterization of a recombinant isolate of Potato virus Y associated with a tomato necrotic disease occurring in Italy.
The results seem to support the hypothesis that PVYC-to is a recombinant isolate of the PVYC2 strain group, and appear to represent an introgression of a PVYO strain group sequence and, in particular, of PVY-OZ, which is a non recombinant isolation of the O lineage.
Complete Nucleotide Sequence of Artichoke latent virus Shows it to be a Member of the Genus Macluravirus in the Family Potyviridae.
Serological relationships and comparisons of the CP gene and of the partial RaLV sequence available all indicate that RaLV should not be considered as a distinct species but as a strain of ArLV, and the spectrum of currently used ArLV-specific molecular hybridization or polymerase chain reaction detection assays should be improved to cover all isolates and strains in the ArLV species.
