Although viruses are most often studied as pathogens, many are beneficial to their hosts,
providing essential functions in some cases and conditionally beneficial functions in others …

The infection and replication of viruses in the host induce diverse mechanisms for combating
viral infection. One of the best-studied antiviral defence mechanisms is based on RNA …

RNA-silencing mechanisms control many aspects of gene regulation including the detection
and degradation of viral RNA through the action of, among others, Dicer-like and Argonaute …

In contrast to viruses of plants and animals, viruses of fungi, mycoviruses, uniformly lack an
extracellular phase to their replication cycle. The persistent, intracellular nature of the …

One of the challenges being faced in the twenty-first century is the biological control of plant
viral infections. Among the different strategies to combat virus infections, those based on …

SUMMARY A rice cDNA library was screened by a galactosidase 4 (Gal4)‐based yeast two‐
hybrid system with Rice stripe virus (RSV) p2 as bait. The results revealed that RSV p2 …

Cellular organisms have evolved related pathways for the biogenesis and function of small
interfering RNAs (siRNAs), microRNAs and PIWI-interacting RNAs (piRNAs). These distinct …

In Arabidopsis, micro (mi) RNAs and trans-acting (ta-si) RNAs synthesized directly or
indirectly through the DICER-LIKE-1 (DCL1) ribonuclease have roles in patterning and …

Tobamoviruses encode a silencing suppressor that binds small RNA (sRNA) duplexes in
vitro and supposedly in vivo to counteract antiviral silencing. Here, we used sRNA deep …

Many viruses infecting animals and plants share common cores of homologous genes
involved in the key processes of viral replication. In contrast, genes that mediate virus–host …
