Eggplant latent viroid: a friendly experimental system in the family Avsunviroidae
Molecular plant pathology, 2016Co-Authors: José-antonio DaròsAbstract:TAXONOMY Eggplant latent viroid (ELVd) is the only species of the genus Elaviroid (family Avsunviroidae). All the viroids in the family Avsunviroidae contain hammerhead ribozymes in the strands of both polarities, and are considered to replicate in the chloroplasts of infected cells. This family includes two other genera: Avsunviroid and Pelamoviroid. PHYSICAL PROPERTIES ELVd consists of a single-stranded, circular, non-coding RNA of 332-335 nucleotides that folds in a branched quasi-rod-like minimum free-energy conformation. RNAs of complementary polarity exist in infected cells and are considered to be replication intermediates. Plus (+) polarity is assigned arbitrarily to the strand that accumulates at a higher concentration in infected tissues. HOST: To date, ELVd has only been shown to infect eggplant (Solanum melongena L.), the species in which it was discovered. A very narrow host range seems to be a common property in members of the family Avsunviroidae. SYMPTOMS ELVd infections of eggplants are apparently symptomless. TRANSMISSION ELVd is transmitted mechanically and by seed. USEFUL WEBSITE http://subviral.med.uottawa.ca.

ICTV Virus Taxonomy Profile: Avsunviroidae.
The Journal of general virology, 2018Co-Authors: Francesco Di Serio, Jaroslav Matoušek, Robert A. Owens, Vicente Pallás, John W. Randles, Teruo Sano, Jacobus Th.j. Verhoeven, Georgios Vidalakis, Ricardo FloresAbstract:Members of the family Avsunviroidae have a single-stranded circular RNA genome that adopts a rod-like or branched conformation and can form, in the strands of either polarity, hammerhead ribozymes involved in their replication in plastids through a symmetrical RNA–RNA rolling-circle mechanism. These viroids lack the central conserved region typical of members of the family Pospiviroidae. The family Avsunviroidae includes three genera, Avsunviroid, Pelamoviroid and Elaviroid, with a total of four species. This is a summary of the ICTV Report on the taxonomy of the family Avsunviroidae, which is available at http://www.ictv.global/report/Avsunviroidae.
