Question

TMV was first isolated in crystalline state by?

Answer 1

Tobacco mosaic virus (TMV) is a positive-sense single stranded RNA virus, genus tobamovirus that infects a wide range of plants, especially tobaccoand other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name). TMV was the first virus ever to be discovered. Although it was known from the late 19th century that an infectious diseasewas damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus. It is the first pathogen identified as a virus.
