Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae.The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name). Only when patterns in green and yellow appear on the leaves would you know that this is a virus.

Bacillus thuringiensis is a naturally occurring soil bacterium that causes disease on insect pests. “This is an unbelievably powerful process.” By cordoning off viral replication into membrane-bound compartments, the factories also serve to protect the pathogen against the plant immune system. ¿Por qué no compartes? Begomovirus is a genus of viruses, in the family Geminiviridae. The sequences have been submitted to the gene bank. In view of the ease of purification (it can be purified in high yield from naturally infected bromegrass), cursory physical characterization is advisable for purposes of identification.
