Based on the types of host, viruses are of different types.i.e., plant viruses, animal viruses, bacteriophages, cyanophages, zymophages and mycophages.
Plant viruses (Phytophages) principally attack plants and majority of them possess single stranded RNA. Plant viruses or reoviridae contain of RNA as genetic material.
Example: The wound tumour virus, Califlower virus and dahlia mosiac virus contain dsDNA as their genetic material. No other ssDNA containing plant virus is known so far except Geminivirus.
Animal viruses (Zoophages) are those viruses that principally attack animals and possess double stranded DNA.
Example: Polio virus and influenza virus, however, contain RNA.
Plant Virus vs Animal VirusPlant virus
- Capsid: It is only external boundary.
- Genetic material: RNA
- Nucleic acid strand: Single stranded
- Nature of nucleic acid: Linear
- Infection: Enter through wound or pore
- Capsid: In addition to capsid envelope is also present.
- Genetic material: DNA
- Nucleic acid strand: Double stranded
- Nature of nucleic acid: Linear or Circular
- Infection: Enter through phagocytosis
