Complete sequence of the citrus tristeza virus RNA genome.
Phylogenetic analysis of the three replication-associated domains, MT, HEL, and RdRp, indicates that CTV and BYV form a separate closterovirus lineage within the alpha-like supergroup of positive-strand RNA viruses.

Phylogenetic analyses of their replicative genes as well as the conserved HSP70 demonstrate that closteroviruses co-evolved with their insect vectors, resulting in three major lineages, i.e. aphid-, mealybug-, and whitefly-transmitted viruses.
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.
Characterization of citrus tristeza virus subgenomic RNAs in infected tissue.
Citrus tristeza virus (CTV) specific RNAs extracted from infected citrus tissue were analyzed by Northern blot hybridization and found that the RNAs for the p20 and p23 ORFs were the most abundant and surpassed the amount of the p25 or capsid protein specific subgenomic RNA.
Potato virus Y: An Evolving Concern for Potato Crops in the United States and Canada.
North American potato production differs from other geographical regions such as Europe in that it is essentially a closed system, i.e., seed potatoes are not imported and production is dominated by
Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the
This work proposes to create a new genus termed Torradovirus (type species, Tomato torrado virus) and to assign this genus to the proposed family Secoviridae, a new family of plant viruses that infect plants and use specialized proteins or protein domains to move through their host.
Continuous and emerging challenges of Potato virus Y in potato.
An attempt is made to analyze various properties of the virus and its interactions with potato resistance genes and with aphid vectors to explain this recent PVY spread in potato production areas.
Nucleotide sequence and organization of eight 3' open reading frames of the citrus tristeza closterovirus genome.
A specific four-gene module consisting of thehsp70 protein, the hsp90-related protein, a diverged copy of the CP, and the CP itself was found to be common in organization between CTV and beet yellows closterovirus, indicating that these viruses probably have evolved from a common ancestor.
Organization of the 3'-terminal half of beet yellow stunt virus genome and implications for the evolution of closteroviruses.
The double-stranded RNA "replicative form" of the BYSV was demonstrated to have a nontemplate G residue at the 3' terminus of the (+) strand, which suggests that these three viruses might represent three distinct but probably close stages in the closterovirus evolution.
