Viruses and Plants

Satellite RNAs and Satellite Viruses of Plants

The view that satellite RNAs (satRNAs) and satellite viruses are purely molecular parasites of their cognate helper viruses has changed. The molecular mechanisms underlying the synergistic and/or antagonistic interactions among satRNAs/satellite viruses, helper viruses, and host plants are beginning to be comprehended. This review aims to summarize the recent achievements in basic and practical...

How RNA Interference Combat Viruses in Plants

The coevolution of plants and viruses: resistance and pathogenicity.

Virus infection may damage the plant, and plant defenses are effective against viruses; thus, it is currently assumed that plants and viruses coevolve. However, and despite huge advances in understanding the mechanisms of pathogenicity and virulence in viruses and the mechanisms of virus resistance in plants, evidence in support of this hypothesis is surprisingly scant, and refers almost only t...

Gene silencing: Plants and viruses fight it out

Plants can become 'immune' to attack by viruses by degrading specific viral RNA, but some plant viruses have evolved the general capacity to suppress this resistance mechanism.
