What effects do plant viruses have on plants?
Leaf curling, yellowing of veins and stunted plant growth.
As with most viruses they can only accurately be identified under an electron microscope as they are extremely small (basically DNA with a protein shell). The effects of certain plant viruses can however been seen on certain plants. Tobacco Mosaic Virus for example is well known and the effects are seen as light, regular mottling on the leaves (mainly plants of the family Solonaceae - tobacco, tomato's, potato and petunia). This will eventually cause the…

Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
