Viral-induced systemic necrosis in plants involves both programmed cell death and the inhibition of viral multiplication, which are regulated by independent pathways.
It is suggested that systemic necrosis and HR consist of PCD and a restraint of virus multiplication, and that the latter is induced through unknown pathways independent from the former. Expand
In Planta Recognition of a Double-Stranded RNA Synthesis Protein Complex by a Potexviral RNA Silencing Suppressor[C][W][OPEN]
It is demonstrated that transgenic expression of TGBp1 of plantago asiatica mosaic virus (PlAMV) induced developmental abnormalities in Arabidopsis thaliana similar to those observed in mutants of SUPPRESSOR of GENE SILENCING3 and RNA-DEPENDENT RNA POLYMERASE6 required for the trans-acting small interfering RNA synthesis pathway.

Variability in the level of RNA silencing suppression caused by triple gene block protein 1 (TGBp1) from various potexviruses during infection.
It is suggested that suppressor activities differ even among homologous proteins encoded by viruses of the same genus, and that TGBp1 contributes to the variation in the level of RNA silencing suppression by potexviruses. Expand
The N-terminal region of the Plantago asiatica mosaic virus coat protein is required for cell-to-cell movement but is dispensable for virion assembly.
Results support the concept that the N-terminal region of potexvirus CP can be separated into two distinct functional domains. Expand
Efficient foreign gene expression in planta using a plantago asiatica mosaic virus-based vector achieved by the strong RNA-silencing suppressor activity of TGBp1
The construction of an expression vector based on plantago asiatica mosaic virus (PlAMV), a member of the genus Potexvirus, showed that the GFP expression construct PlAMV-GFP exhibits stronger RNA silencing suppression activity than PVX-G FP, which is likely to contribute to the stability of the PlAMv vector.

Genetic heterogeneity found in the replicase gene of poinsettia mosaic virus isolates
The complete nucleotide sequences of five isolates of poinsettia mosaic virus from Japan were determined and the JO isolates were found to possess eight common translational frameshift sites in the interdomain region between the methyltransferase and protease domains, suggesting that PnMV might have evolved by creating variations in its genome by such translationalframeshifts.

A Dual Strategy for the Suppression of Host Antiviral Silencing: Two Distinct Suppressors for Viral Replication and Viral Movement Encoded by Potato Virus M
A sophisticated viral infection strategy that suppresses host antiviral silencing at two different steps via two mechanistically distinct suppressors is demonstrated through analysis of the suppressors encoded by potato virus M. Expand
