Complete sequence of the citrus tristeza virus RNA genome.
TLDR
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.

Sequences of Citrus Tristeza VirusSeparated in Time and Space Are Essentially Identical
ABSTRACT 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 sequence…

Examination of the responses of different genotypes of citrus to huanglongbing (citrus greening) under different conditions.
TLDR
Examination of responses of 30 different genotypes of citrus to Florida isolates of 'Ca. L. asiaticus' provides additional evidence of the correlation between disruption of phloem translocation of carbohydrates during HLB infection and the appearance of chlorotic symptoms in leaves of infected trees.

Closterovirus bipolar virion: evidence for initiation of assembly by minor coat protein and its restriction to the genomic RNA 5' region.
The long flexuous virions of the Closteroviridae have a unique bipolar architecture incorporating two coat proteins, with most of the helical nucleocapsid encapsidated by the major coat protein (CP)…

Nucleotide sequence and organization of eight 3' open reading frames of the citrus tristeza closterovirus genome.
TLDR
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.

In planta distribution of 'Candidatus Liberibacter asiaticus' as revealed by polymerase chain reaction (PCR) and real-time PCR.
TLDR
It is found that 'Ca. Liberibacter asiaticus' was distributed in bark tissue, leaf midrib, roots, and different floral and fruit parts, but not in endosperm and embryo, of infected citrus trees, and was transmitted systemically from infection site to different parts of the plant.

The p23 Protein of Citrus Tristeza Virus Controls Asymmetrical RNA Accumulation
TLDR
The p23 protein controls asymmetric accumulation of CTV RNAs by downregulating negative-stranded RNA accumulation and indirectly increases expression of 3′ genes.

The complete nucleotide sequence and genome organization of the M RNA segment of peanut bud necrosis tospovirus and comparison with other tospoviruses.
TLDR
The M RNA of peanut bud necrosis virus comprised two ORFs in an ambisense organization and terminal inverted repeats and was identified as the glycoprotein precursor of the G1 and G2 glycoproteins.

Closterovirus encoded HSP70 homolog and p61 in addition to both coat proteins function in efficient virion assembly.
TLDR
The involvement of gene products of Citrus tristeza virus (CTV) in virion formation was examined and it was found that the chaperone-like protein plus the p61 and both coat proteins were required for efficient virion assembly.

An engineered closterovirus RNA replicon and analysis of heterologous terminal sequences for replication.
TLDR
To investigate the origin and maintenance of the genotypes in CTV populations, the CTV replicase was tested for its acceptance of divergent sequences by creating chimeric replicons with heterologous termini and examining their ability to replicate.
