A Viroid Resembling Hop Stunt Viroid in Infected Apple Trees with Apple Scar Skin Disease in the Northeast of Iran
Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...
متن کاملRegulation of pathogenicity in hop stunt viroid-related group II citrus viroids.
Nucleotide sequences were determined for two hop stunt viroid-related Group II citrus viroids characterized as either a cachexia disease non-pathogenic variant (CVd-IIa) or a pathogenic variant (CVd-IIb). Sequence identity between the two variants of 95.6% indicated a conserved genome with the principal region of nucleotide difference clustered in the variable (V) domain. Full-length viroid RT-...
متن کاملNudeotkle Sequence of Cucumber Pale Fruit Virotd: Homology to Hop Stunt Viroid
Double stranded cDNA of cucumber pale fruit viroid (CPFV) has been cloned by the method of Okayama and Berg (Mol.Cell.Biol.2,161-170 (1982)) and the complete nucleotide sequence was established. The covalently closed circular molecules of single-stranded CPFV RNA consists of 303 nucleotides. The nucleotide sequence of CPFV was compared with the previously established sequence of hop stunt viroi...

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...
