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 کاملThe molecular structure of Iresine viroid, a new viroid species from Iresine herbstii ('beefsteak plant').
A viroid was isolated from Iresine herbstii plants using the bidirectional PAGE method for analysis of small circular RNA molecules. The viroid was transmitted to viroid-free Iresine herbstii plants of the cultivar 'Aureoreticulata' by mechanical inoculation. Infected plants did not develop any symptoms. The new viroid species has been named Iresine viroid (IrVd). It is a member of the potato s...

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 کاملGenomic structure of new Tunisian peach latent mosaic viroid variants.
Peach latent mosaic viroid (PLMVd) is a single-stranded circular RNA that do not code for proteins and ranges in size from 335 to 351 nucleotides. It mainly infects peach. In this study, the sequence of 20 complete cDNA clones derived from seven PLMVd isolates detected in five Tunisian peach cultivars was analysed in 3 steps: primary structure, phylogeny and secondary structure. The analysis of...
متن کاملThe molecular characterization of 16 new sequence variants of Hop stunt viroid reveals the existence of invariable regions and a conserved hammerhead-like structure on the viroid molecule.
At present isolates of Hop stunt viroid (HSVd) are divided into five groups: three major groups (plum-type, hop-type and citrus-type) each containing isolates from only a limited number of isolation hosts and two minor groups that were presumed to derive from recombination events between members of the main groups. In this work we present the characterization of 16 new sequence variants of HSVd...
