Transcript TMV Lesson - NSF Potato Genome

Tobacco mosaic virus
Tobacco mosaic virus (TMV) of plants provides a good model to
learn about the relationship between a virus and its host.
Purpose: to learn about (1) properties of TMV and (2)
symptoms induced by the virus in susceptible and resistant
plant hosts
Background information:
Viruses cause a variety of diseases in plants and animals. Virus
diseases that affect humans include measles, mumps, and
polio. At one time, these diseases posed major health concerns,
but with the widespread use of vaccinations in children, these
diseases occur rarely.
Tobacco Mosaic Virus Infection Lesson:
Transmission of Virus and Mosaic Disease
1. View healthy and infected tobacco and tomato plats
1. Observe crushing of healthy and mosaic diseased tomato leaves in buffer
using mortar and pestle to produce virus infected plant sap.
2. Mark tobacco leaves with your initials using Sharpie.
3. Use sponge to rub TMV sap from crushed leaves onto your marked healthy
tobacco leaf.
