Citrus tristeza virus-host interactions
Citrus tristeza virus (CTV) is a phloem-limited virus whose natural host range is restricted to citrus and related species. Although the virus has killed millions of trees, almost destroying whole industries, and continually limits production in many citrus growing areas, most isolates are mild or symptomless in most of their host range. There is little understanding of how the virus causes sev...
متن کاملThe Complex Genetics of Citrus tristeza virus
The 2000 x 11 nm long bipolar flexuous filamentous particles of Citrus tristeza virus (CTV) (genus Closterovirus, family Closteroviridae) (Figure 1) contain a single-stranded positive-sense RNA genome of 19.3 kb, which is encapsidated in two different capsid proteins that coat the opposite ends of the virions [1, 2]. CTV is the largest identified RNA virus infecting plants and the second larges...
متن کاملSurvey methods for assessment of citrus tristeza virus incidence.
ABSTRACT The assessment of citrus tristeza virus incidence by sampling involves laboratory testing by enzyme-linked immunosorbent assay of leaf material collected in the field. Using field data and computer simulation, methods of field data collection were compared. One method was similar to that used by the Central California Tristeza Eradication Agency, in which 4 to 6% of the trees in a plan...
متن کاملBacterial expressed coat protein: development of a single antiserum for routine detection of Citrus Tristeza Virus
Citrus tristeza virus (CTV, genus Closterovirus, family Closteroviridae) is the largest member of its taxonomic family. Viral particles, 2000 nm in length and 10–12 nm in diameter, are present in the phloem of infected plants. A single stranded positive sense RNA molecule approximately 20,000 nucleotides long constitutes its genome (BarBacterial expressed coat protein: development of a single a...
متن کاملEmergence and Phylodynamics of Citrus tristeza virus in Sicily, Italy
Citrus tristeza virus (CTV) outbreaks were detected in Sicily island, Italy for the first time in 2002. To gain insight into the evolutionary forces driving the emergence and phylogeography of these CTV populations, we determined and analyzed the nucleotide sequences of the p20 gene from 108 CTV isolates collected from 2002 to 2009. Bayesian phylogenetic analysis revealed that mild and severe C...
