Viruses are constantly subject to natural selection to enrich beneficial mutations and weed out deleterious ones. However, it remains unresolved as to how the phenotypic gains or losses brought about by these mutations cause the viral genomes carrying the very mutations to become more or less numerous. Previous investigations by us and others sugge...

... Both the repeated results and the analysis of the information have strengthened the proposal of the BIAS hypothesis (bottleneck, isolate, amplify, select), which states, in summary, that at least (+) RNA viruses limit the number of replicable genomes per cell, using what is called a bottleneck to prevent their replication, in such a way that stochastically only a few managed to do so. A few escaped viral genomes that are isolated from each other in separate cells and in these bottle isolated genomes where the viral genomes that can establish and multiply are selected [81][82][83]. ...
Viral diseases are a frequent problem in the agricultural sector, causing significant economic losses, so their management is a constant challenge for producers and researchers. One of the factors that often complicates the control of viral diseases in plants is mixed infections, which occur when two or more viruses are present in a plant, generating a complex expression of symptoms. During a mixed infection, the following types of interactions basically occur: complementation and interference, the effect of which produces synergism, antagonism, or no effect. However, there are also subcategories of effects. This makes early detection difficult, and this infection can also give a competitive advantage to the pathogens involved. This review presents updated information on mixed viral infections in plants, the interaction categories, the severity of symptoms, and the impact on plants and vectors. The intention is to share information to better understand the etiology of the diseases.
