Viroids are autonomously replicating, small singlestranded circular RNA molecules that do not code for proteins and may cause disease in infected, susceptible plants. Viroids have the ability to induce both RNA-mediated transcriptional gene silencing (TGS) and posttranscriptional gene silencing (PTGS) in infected plants. Viroid PTGS has also been demonstrated in a wheat germ extract system. A p...
متن کاملHost-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 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...
متن کاملCitrus Bent Leaf Viroid from Fars Province of Iran
Background and Aims: CBLVd has been reported from northern of Iran previously. The aim of this study was evaluating new viroid variant from asymptomatic citrus trees of Fars province and comparing with its other isolates. Materials and Methods: In this study a number of citrus trees without symptoms were sampled and subjected to RNA extraction followed by RT-PCR, cloning and sequencing of ...
