Lectin-Mediated Resistance Impairs Plant Virus Infection at the Cellular Level[C][W][OA]
TLDR
Analysis of resistance of certain Arabidopsis thaliana ecotypes to a potexvirus to show the existence of lectin genes that show a variety of levels of virus resistance, their targets, and their properties, which are distinct from those of known R genes, suggests the generality of Lectin-mediated resistance in plant innate immunity. Expand
Viral-induced systemic necrosis in plants involves both programmed cell death and the inhibition of viral multiplication, which are regulated by independent pathways.
TLDR
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]
TLDR
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.

Fig mosaic emaravirus p4 protein is involved in cell-to-cell movement.
TLDR
A series of experiments revealed that FMV-p4 has the capacity to complement viral cell-to-cell movement, prompt GFP diffusion between cells, and spread by itself to neighbouring cells. 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
TLDR
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.

New Detection Systems of Bacteria Using Highly Selective Media Designed by SMART: Selective Medium-Design Algorithm Restricted by Two Constraints
TLDR
A novel strategy for designing highly selective media based on two selective agents, a carbon source and antimicrobials that facilitates not only the development of novel techniques for detecting specific bacteria, but also the understanding of the ecology and epidemiology of the targeted bacteria. Expand
A necrosis-inducing elicitor domain encoded by both symptomatic and asymptomatic Plantago asiatica mosaic virus isolates, whose expression is modulated by virus replication.
TLDR
The data suggest that necrotic symptoms induced by PlAMV infection depend on the accumulation of a non-isolate specific elicitor HEL (even from nonnecrosis isolates), whose expression is indirectly regulated by amino acid 1,154 that controls replication. Expand
Identification of three MAPKKKs forming a linear signaling pathway leading to programmed cell death in Nicotiana benthamiana
TLDR
A comparative functional analysis of MAPKKKs is performed to investigate the signaling pathway leading to the defense response and demonstrates that in addition to NbMAPKKKα, NbMapKKKβ and NbmapKKKγ also function as positive regulators of PCD. Expand
Cell Death Triggered by a Putative Amphipathic Helix of Radish mosaic virus Helicase Protein Is Tightly Correlated With Host Membrane Modification.
TLDR
Results indicate that ER membrane modification associated with viral intracellular replication may be recognized to prime defense responses against plant viruses. Expand
Pseudo-polyprotein translated from the full-length ORF1 of capillovirus is important for pathogenicity, but a truncated ORF1 protein without variable and CP regions is sufficient for replication.
TLDR
The results of in vivo reporter assays suggested that the mechanism of this early termination of capillovirus ORF1 is a ribosomal -1 frame-shift occurring downstream from the conserved Rep domains. Expand
