Plants respond to pathogens using elaborate networks of genetic interactions. Recently,
significant progress has been made in understanding RNA silencing and how viruses …

Genetic resistance to plant viruses has been used for at least 80 years to control agricultural
losses to viral diseases. To date, hundreds of naturally occurring genes for resistance to …

RNA silencing in plants likely exists as a defense mechanism against molecular parasites
such as RNA viruses, retrotransposons, and transgenes. As a result, many plant viruses …

Plant viruses are biotrophic pathogens that need living tissue for their multiplication and
thus, in the infection–defence equilibrium, they do not normally cause plant death. In some …

Posttranscriptional gene silencing (PTGS), or RNA silencing, is a sequence-specific RNA
degradation process that targets foreign RNA, including viral and transposon RNA for …

The natural outcome of some plant–virus interactions is symptom recovery, which is
characterized by the emergence of asymptomatic leaves following a systemic symptomatic …

Plants employ multiple layers of innate immunity to fight pathogens. For both RNA and DNA
viruses, RNA silencing plays a critical role in plant resistance. To escape this antiviral …

Plants respond to pathogens using an innate immune system that is broadly divided into PTI
(pathogen-associated molecular pattern-or PAMP-triggered immunity) and ETI (effector …

Plant and animal viruses overcome host antiviral silencing by encoding diverse viral
suppressors of RNA silencing (VSRs). Prior to the identification and characterization of their …

▪ Abstract Although many subviral RNAs reduce or intensify disease symptoms caused by
the helper virus, only recently have clues concerning the mechanism of disease modulation …
