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 کاملThe p23 Protein from Citrus tristeza virus is a Pathogenicity Determinant in Transgenic Citrus Hosts
The 23 kDa protein (p23) coded by the 3 -terminal gene of Citrus tristeza virus (CTV), is a RNA-binding protein that contains a motif rich in cysteine and histidine residues in the core of a putative zinc-finger domain. Transgenic Mexican lime plants were generated carrying a p23 transgene, or a truncated version thereof, under the control of the Cauliflower mosaic virus (CaMV) 35S promoter. Ec...
متن کاملPast and future of a century old Citrus tristeza virus collection: a California citrus germplasm tale
Citrus tristeza virus (CTV) isolates collected from citrus germplasm, dooryard and field trees in California from 1914 have been maintained in planta under quarantine in the Citrus Clonal Protection Program (CCPP), Riverside, California. This collection, therefore, represents populations of CTV isolates obtained over time and space in California. To determine CTV genetic diversity in this conte...
متن کاملAmplification of Citrus tristeza virus from a cDNA clone and infection of citrus trees.
Isolates of the Closterovirus, Citrus tristeza virus (CTV), are populations of disparate genotypes and defective RNAs developed during long periods of vegetative propagation of citrus trees. Because it has not been possible to obtain pure cultures of the virus, it is not known what components of the population are primarily responsible for induction of diseases. We previously developed an infec...
