Plant viruses exhibit a diverse range of genome types, but the most common type is single-stranded RNA (ssRNA). Examples include Tobacco Mosaic Virus (TMV), Potato Virus Y (PVY), and many others. While other genome types like double-stranded RNA (dsRNA), single-stranded DNA (ssDNA), and double-stranded DNA (dsDNA) also exist in plant viruses, ssRNA viruses are predominant.
Knowing the typical types of genetic material found in plant viruses is a key aspect of virology.
