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 …

The family Closteroviridae comprises more than 30 plant viruses with flexuous, filamentous
virions and includes representatives with either mono-or bipartite positive-strand ssRNA …

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 …

Amongst the Closteroviridae, Citrus tristeza virus (CTV) is almost unique in possessing a
number of distinct and characterized strains, isolates of which produce a wide range of …

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 …

The first outbreak of citrus tristeza disease in Spain caused by Citrus tristeza virus (CTV) was
recorded in 1957 in the Valencian Community (VC). In total c. 40 million trees, mainly of …

Genetic markers amplified from three noncontiguous regions by sequence specific primers
designed from the partial or complete genome sequences of Citrus tristeza virus (CTV) …

The first Citrus tristeza virus (CTV) genomes completely sequenced (19.3-kb positive-sense
RNA), from four biologically distinct isolates, are unexpectedly divergent in nucleotide …

Citrus tristeza virus (CTV) populations in citrus trees are unusually complex mixtures of viral
genotypes and defective RNAs developed during the long-term vegetative propagation of …

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 …
