RNA silencing is a homology-dependent gene inactivation mechanism that regulates a wide
range of biological processes including antiviral defense. To deal with host antiviral …

Adaptation to specialized environments allows microorganisms to inhabit an enormous
variety of ecological niches. Growth inside plant tissues is a niche offering a constant …

The P0 protein of poleroviruses and P1 protein of sobemoviruses suppress the plant's RNA
silencing machinery. Here we identified a silencing suppressor protein (SSP), P0PE, in the …

The genus Sobemovirus, unassigned to any family, consists of viruses with single-stranded
plus-oriented single-component RNA genomes and small icosahedral particles. Currently …

One of the systems of plant defense against viral infection is RNA silencing, or RNA
interference (RNAi), in which small RNAs derived from viral genomic RNAs and/or mRNAs …

The sobemoviruses have one of the smallest of all known RNA virus genomes. ORF1
encodes P1 which plays a role in suppression of silencing and virus movement, ORFs 2a …

In plants RNA silencing is a host defense mechanism against viral infection, in which double‐
strand RNA is processed into 21–24‐nt short interfering RNA (siRNA). Silencing spreads …

RNA silencing suppressor genes derived from six virus genera were transformed into
Nicotiana benthamiana and N. tabacum plants. These suppressors were P1 of Rice yellow …

RNA interference (RNAi) is a sequence-specific, gene silencing mechanism, induced by
double-stranded RNA (dsRNA). It is a defense mechanism that protects eukaryotic cells from …

Viruses of the sobemovirus genus are plant viruses, most of which generate very important
agricultural and financial losses. Among them, the rice yellow mottle virus (RYMV) is one of …
