Three distinct suppressors of RNA silencing encoded by a 20-kb viral RNA genome.
A sophisticated viral counter-defense strategy that targets the silencing antiviral pathway at multiple steps is revealed and may be essential for protecting CTV with such a large RNA genome from antiviral silencing in the perennial tree host.
Genetic Variation of Citrus Tristeza VirusIsolates from California and Spain: Evidence for Mixed Infections and Recombination
Examination of the population structure and genetic variation of four genomic regions within and between 30 Citrus tristeza virus isolates from Spain and California suggested that the genomes of some CTV sequence variants originated by recombination events between diverged sequence variants.
The family Closteroviridae revised
The mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine), and the family now comprises three genera.
Genome structure and phylogenetic analysis of lettuce infectious yellows virus, a whitefly-transmitted, bipartite closterovirus.
The complete nucleotide sequences of lettuce infectious yellows virus (LIYV) RNAs 1 and 2 are reported and it is suggested that the RdRp domain is expressed independently of the other replication-associated domains via a + 1 ribosomal frameshift.
Virus-vector interactions mediating nonpersistent and semipersistent transmission of plant viruses.

Evidence suggests that two general strategies, the capsid and helper strategies, are found for plant viruses that are transmitted by aphids in a nonpersistent manner are found also for viruses transmitted in a semipersistent manner.
Biology and molecular biology of viruses in the genus Tenuivirus.
The combination of characteristics exhibited by Tenuiviruses are quite different than those found for most plant viruses and are more similar to vertebrate-infecting viruses in the genus Phlebovirus of the Bunyaviridae.
Lettuce infectious yellows virus: in vitro acquisition analysis using partially purified virions and the whitefly Bemisia tabaci.
Virions of lettuce infectious yellows virus (LIYV; genus Crinivirus) were purified from LIYV-infected plants and their protein composition was analysed by SDS-PAGE and immunoblotting. Virion
Population Structure and Genetic Diversity within California Citrus tristeza virus (CTV) Isolates
Comparisons with those from other isolates suggests that some CTV isolates could have arisen as result of a mixed infection of two divergent isolates, and the genetic diversity within and between isolates by analysis of haplotype nucleotide sequences.
Geographically distant isolates of the crinivirus Cucurbit yellow stunting disorder virus show very low genetic diversity in the coat protein gene.
Analysis of 71 isolates collected from Spain, Jordan, Turkey, Lebanon, Saudi Arabia and North America showed that these isolates could be divided into two diverged subpopulations: an Eastern subpopulation composed of Saudi Arabian isolates and a Western subpopulation containing the rest of the CYSDV isolates.
