Lectin-Mediated Resistance Impairs Plant Virus Infection at the Cellular Level[C][W][OA]
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.

Recognition of floral homeotic MADS domain transcription factors by a phytoplasmal effector, phyllogen, induces phyllody
It is found that PHYL1 interacts with and degrades the floral homeotic MADS domain proteins SEPALLATA3, APETALA1 (AP1) and CAULIFLOWER (CAL), which induces morphological changes in flowers that are similar to those seen in phytoplasma-infected plants. Expand
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
The phytoplasmal virulence factor TENGU causes plant sterility by downregulating of the jasmonic acid and auxin pathways
TENGU, a phytoplasmal virulence peptide known as a dwarfism inducer, acts as an inducer of sterility in Arabidopsis thaliana flowers and is the first virulence factor with the effects on plant reproduction by perturbation of phytohormone signaling. 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.

Cloning of immunodominant membrane protein genes of phytoplasmas and their in planta expression.
Phytoplasmas are plant pathogenic bacteria that cause devastating yield losses in diverse crops worldwide. Although the understanding of the pathogen biology is important in agriculture, theExpand
Identification and characterization of two novel genomic RNA segments of fig mosaic virus, RNA5 and RNA6.
Sequence analysis showed that the novel RNA segments found in FMV isolates are similar, in their structural organization and molecular evolutionary patterns, to those of known FMV genomic RNA segments. Expand
Genomic and evolutionary aspects of phytoplasmas
Current knowledge of the diversity and common features of phytoplasma genomes are summarized, including the factors responsible for pathogenicity. Expand
Molecular epidemiology of Plum pox virus in Japan.
The relationships of the PPV-D strain were reconstructed with high resolution: at the global level, the American, Canadian, and Japanese isolates formed their own distinct monophyletic clusters, suggesting that the routes of viral entry into these countries were independent. Expand
