"Viroids" Pronounce,Meaning And Examples

"Viroids" Meaning

A viroid is a small infectious agent that is smaller than a virus but larger than a protein. It replicates itself using the host cell's machinery and can cause disease in plants and insects. Unlike viruses, viroids do not have a protein coat, and their genetic material is either single-stranded RNA or a single strand of circular RNA.

The main difference between viruses and viroids is that viruses have a protein coat called a capsid that surrounds their genetic material, whereas viroids do not. This lack of a protein coat makes viroids more difficult to detect and study than viruses.

Viroids are typically transmitted through plant-to-plant contact and can cause a range of diseases in plants, including potato spindle tuber virescence (in potatoes), corky bark (in avocado), and pear blister canker (in pears).
