Signaling Pathway Analysis and Downstream Genes Associated with Disease Resistance Mediated by GmSRC7 [PDF]
GmSRC7 is a broad-spectrum antiviral R gene from soybean, but its downstream and functionally related genes remain unclear. Virus-induced gene silencing (VIGS) assays in Nicotiana benthamiana (Nb) showed that suppression of several gene families—WRKY ...

Anti-TMV activity of malformin A1, a cyclic penta-peptide produced by an endophytic fungus Aspergillus tubingensis FJBJ11. [PDF]
Plant-associated microorganisms are known to produce a variety of metabolites with novel structures and interesting biological activities. An endophytic fungus FJBJ11, isolated from the plant tissue of Brucea javanica (L.) Merr. (Simaroubaceae), was proven to be significantly effective in producing metabolites with anti-Tobacco mosaic virus (TMV ...

Anti-TMV Activities of Pantoea agglomerans Lipopolysaccharides in vitro [PDF]
Today there are no antiviral drugs of chemical nature that can completely cure virus-infected plants. The fact that their effect is limited to minimizing the pathogenic effect of viruses motivates many researchers to look for alternatives. In recent years it has been shown that lipopolysaccharides (LPS) of some bacteria, in particular representatives ...

RNA-dependent RNA polymerase 1 in potato (Solanum tuberosum) and its relationship to other plant RNA-dependent RNA polymerases. [PDF]
Cellular RNA-dependent RNA polymerases (RDRs) catalyze synthesis of double-stranded RNAs that can serve to initiate or amplify RNA silencing. Arabidopsis thaliana has six RDR genes; RDRs 1, 2 and 6 have roles in anti-viral RNA silencing.
