Viruses can infect bacteria and are commonly known as bacteriophages. They attach to bacterial cells and inject their genetic material, leading to the production of new viral particles within the bacterial host. Viruses that infect fungi are termed mycoviruses. These viruses can influence the physiology and pathogenicity of their fungal hosts. Notably, studies have shown that fungi can acquire viruses and viroids from plants, indicating cross-kingdom transmission. Numerous viruses infect plants, causing a variety of diseases that can significantly impact agricultural productivity. These plant viruses can be transmitted through various means, including insect vectors, mechanical damage, and seed transmission. Ex-Tobacco Mosaic Virus (TMV), infect plants, causing diseases that affect crop yields and quality.
