Plant viruses cause considerable economic losses and are a threat for sustainable
agriculture. The frequent emergence of new viral diseases is mainly due to international …

Citrus tristeza virus (CTV)(genus Closterovirus, family Closteroviridae) is the causal agent of
devastating epidemics that changed the course of the citrus industry. Adapted to replicate in …

Superinfection exclusion, a phenomenon in which a preexisting viral infection prevents a
secondary infection with the same or a closely related virus, has been described for various …

We examined the population structure and genetic variation of four genomic regions within
and between 30 Citrus tristeza virus (CTV) isolates from Spain and California. Our analyses …

▪ Abstract Like many other plant RNA viruses, Wheat streak mosaic virus (WSMV) sequence
diversity within and among infected plants is low given the large number of virions produced …

RNA viruses have a great potential for genetic variation, rapid evolution and adaptation.
Characterization of the genetic variation of viral populations provides relevant information on …

Superinfection exclusion or homologous interference, a phenomenon in which a primary
viral infection prevents a secondary infection with the same or closely related virus, has …

Citrus tristeza virus (CTV) causes two citrus diseases that have caused devastating losses in
global citrus production. The first disease is quick decline of trees propagated on the sour …

The genetic variability and population structure of a collection of 45 Grapevine leafroll-
associated virus 3 (GLRaV-3) isolates were studied by single-stranded conformation …

The population structure and genetic variation of Cucurbit yellow stunting disorder virus
