Nucleotide sequence and secondary structure of apple scar skin viroid.
The complete nucleotide sequence of apple scar skin viroid(ASSV) has been established, and a probable secondary structure is proposed. A single-stranded circular ASSV RNA consists of 330 nucleotides and can assume the rodlike conformation with extensive base-pairing characteristic of all the known viroids. ASSV shows low sequence homologies with other viroids and lacks the central conserved reg...

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 کاملChrysanthemum stunt viroid: primary sequence and secondary structure.
The sequence of the 356 nucleotide residues of chrysanthemum stunt viroid (CSV) has been determined. Overlapping linear viroid fragments were obtained by partial ribonuclease digestion, radiolabelled in vitro at their 5'-ends, and sequenced using partial enzymic cleavage methods. Of the CSV sequence, 69% is contained in the published sequence of potato spindle tuber viroid (PSTV). Differences i...
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...
