Interpretive Summary:

Technical Abstract: Revolutionary theoretical concepts derived from experimental evolution have reached the realm of plant viruses, and their empirical demonstration is opening new avenues for disease management. From a populational standpoint, plant viruses and viroids constitute dynamic spectra of variants. The frequency of these variants in the population is determined by a network of molecular interactions occurring among co-infecting particles and between virus- and host-encoded elements. With the development of systems biology and second-generation sequencing approaches, the rules governing these interactions are beginning to be elucidated. Altogether, they define the rate and degree of virus adaptation to new host and vector environments. Based on the reviewed data of plant virus evolution, cause-oriented strategies for virus exclusion and host resistance improvement are highlighted.
