Students will grow their own bean plants and then inoculate them with tobacco mosaic virus (TMV) that they will prepare in class from cigarette tobacco extracts. They will compare the effects of extracts prepared in distilled water versus milk to a control in order to determine if any potential inhibitory properties for TMV exist.
