Genetic variation of populations of Citrus psorosis virus.
Citrus psorosis virus (CPsV), the type species of genus Ophiovirus, has a segmented, negative-stranded RNA genome. We examined the population structure and genetic variation of CPsV in three coding regions located in RNAs 1, 2 and 3, analysing 22 isolates from Argentina, California, Florida, Italy and Spain. Most isolates contained a predominant sequence and some minor variants. Estimations of ...
متن کاملIndexing Tools for Indian Citrus Ringspot Virus (ICRSV)
Indian citrus ringspot virus (ICRSV) is known to cause serious disease problem in Kinnow (Citrus nobilis Lour C. deliciosa Tenora). This paper reports the various methods viz. Bioassay, ELISA and RT-PCR for indexing of ICRSV. Bioassay was performed on Chenopodium amaranticolor, Cucumis sativus, Nicotiana glutinosa, N. tabacum, Petunia hybrida and Phaseolus vulgaris. However necrotic local lesio...
متن کاملCitrus 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 کاملIdentification and genomic characterization of a new virus (Tymoviridae family) associated with citrus sudden death disease.
Citrus sudden death (CSD) is a new disease that has killed approximately 1 million orange trees in Brazil. Here we report the identification of a new virus associated with the disease. RNAs isolated from CSD-affected and nonaffected trees were used to construct cDNA libraries. A set of viral sequences present exclusively in libraries of CSD-affected trees was used to obtain the complete genome ...
