Question

Do Viroids only infect plants?

Answer 1

Infection of viroids:

1. Small, circular, single-stranded RNAs called viroids are contagious diseases.
2. Indeed, viroids exclusively infect plants.
3. They don't have a protein coating like viruses do.
4. All known viroids are angiosperm residents, and the majority of them cause diseases with vastly varying economic value to people.
5. Infected insects can potentially spread viruses among plants.
6. Viroid infections commonly manifest in plants as stunted development, malformed leaves and fruit, stem necrosis, and ultimately plant death.
