Nucleotide sequence and organization of eight 3' open reading frames of the citrus tristeza closterovirus genome.
The citrus tristeza closterovirus (CTV) RNA genome was cloned as cDNA generated from both CTV-specific double-stranded RNA and genomic RNA, and the sequence of the 3' 7292 nucleotides was determined.… Expand

Comparative sequence analysis of the coat proteins of biologically distinct citrus tristeza closterovirus isolates
The genome of citrus tristeza closterovirus (CTV) consists of a 20 kb single-stranded RNA encapsidated in a 2000 nm long, flexuous particle. Double-stranded (replicative form) RNAs purified from… Expand

Unusual amino-terminal sequence repeat characterizes the capsid protein of dasheen mosaic potyvirus.
The 3'-terminal region of a Florida isolate of dasheen mosaic potyvirus (DMV-LA) genome including the coat protein (CP) gene was cloned and sequenced. Protease digestion was predicted to occur… Expand

The diverged copy of the citrus tristeza virus coat protein is expressed in vivo.
Nucleotide sequence analysis of a portion of the citrus tristeza closterovirus (CTV) genome revealed an open reading frame immediately upstream of the coat protein gene that can encode a protein with… Expand

Molecular characterization of a structural epitope that is largely conserved among severe isolates of a plant virus.
Direct molecular evidence was obtained for the critical role of a single amino acid residue in a structural epitope distinguished by the monoclonal antibody MCA-13, which reacts selectively with… Expand

Variability in the length of the amino terminal sequence contributes to the capsid protein diversity among dasheen mosaic potyvirus isolates
SummaryWestern blot analysis of several dasheen mosaic virus isolates revealed molecular weight differences among their capsid proteins (CPs). Sequence analysis of the CP gene showed that the CP of… Expand
