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

▪ 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 …

When infecting alone, Sweet potato feathery mottle virus (SPFMV, genus Potyvirus) and
Sweet potato chlorotic stunt virus (SPCSV, genus Crinivirus) cause no or only mild …

In eukaryotes, alternative splicing (AS) promotes transcriptome and proteome diversity. The
extent of genome-wide AS changes occurring during a plant-microbe interaction is largely …

Metagenomic surveys and data from next generation sequencing revealed that mixed
infections among plant viruses are probably a rule rather than an exception in natural …

Cross-protection is a phenomenon in which infection of a plant with a mild virus or viroid
strain protects it from disease resulting from a subsequent encounter with a severe strain of …

Novel and severe symptoms of chlorosis, rugosity, leaf strapping and dark green islands,
designated as sweetpotato severe mosaic disease (SPSMD), were caused by dual infection …

Satellite viruses encode structural proteins required for the formation of infectious particles
but depend on helper viruses for completing their replication cycles. Because of this unique …

The occurrence of more than one virus species in a single plant is not uncommon in
cultivated and native plant species. A mixed virus infection may lead to greater disease …

Extraviral components that can influence the accumulation and pathogenesis of their
associated helper viruses are known as 'satellites'. The maintenance of satellites requires …
