[EN] Viroids are infectious agents identified only in plants so far. In contrast to viruses, the genome of viroids is composed of a tiny circular RNA (250-400 nt) not coding for proteins, but containing in its compact ...

[EN] How viroids, tiny non-protein-coding RNAs (250–400 nt), incite disease is unclear. One hypothesis is that
viroid-derived small RNAs (vd-sRNAs; 21–24 nt) resulting from the host defensive response, via RNA silencing,
may ...
[EN] Viroids are tiny infectious agents of plants, consisting exclusively of a small (246–401 nucleotides)
circular RNA lacking protein-coding ability. Likely mimicking structural features of cellular RNAs,
they can ...

[EN] While biogenesis of viroid RNAs is well-known, how they decay is restricted to data involving host RNA silencing. Here we report an alternative degradation pathway operating on potato spindle tuber viroid (PSTVd), the ...

Cherry trees from Spain affected by cherry leaf scorch (CLS), a fungal disease proposed to be caused by Apiognomonia erythrostoma, show symptoms (translucent-chlorotic leaf spots evolving into rusty areas) very similar to ...
[EN] The discovery of viroids about 45 years ago heralded a revolution in Biology: small RNAs comprising around 350 nt were found to be able to replicate autonomously and to incite diseases in certain plants without encoding ...
[EN] Despite being composed by a single-stranded, circular, non-protein-coding RNA of just 246-401 nucleotides (nt), viroids can incite in their host plants symptoms similar to those caused by DNA and RNA viruses, which ...
