Host-directed processing of Citrus exocortis viroid.
Prolonged infection of tomato hybrid (Lycopersicon esculentum x Lycopersicon peruvianum) by Citrus exocortis viroid (CEVd) resulted in viroid-like enlarged structures, detected by gel electrophoresis. This population included two new enlarged variants or D-variants, D-87 and D-76, and three transient species or D-forms, D-38, D-40 and D-43. Sequence analyses exposed a locus near the terminal re...
متن کاملEffect of citrus hosts on the generation , maintenance and 1 evolutionary fate of genetic variability of Citrus exocortis 2 viroid ( CEVd )
22 23 2 SUMMARY 23 Citrus exocortis viroid (CEVd) populations are composed by closely related 24 haplotypes whose frequencies in the population result from the equilibrium 25 between mutation, selection and genetic drift. The genetic diversity of CEVd 26 populations infecting different citrus hosts was studied by comparing 27 populations recovered from infected trifoliate orange and sour orange...
متن کاملNovel variants of citrus exocortis viroid from southern of Iran
Background and Aims: Citrus exocortis disease is naturally limited to citrus plants and causes a serious disease on sensitive rootstocks such as trifoliate orange. The aim of this study was to sample new variants of citrus exocortis viroid from Fars trees with yellowing and suberization symptoms and comparison with other isolates of this viroid. Materials and Methods: A number of symptomat...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
