The PR1 family of pathogenesis-related proteins from tobacco (Nicotiana tabacum L.) leaves is induced by a
variety of pathogenic and chemical agents and is associated with resistance to tobacco mosaic virus. The
majority of the PR1 proteins did not copurify with mesophyll protoplasts (the major cell type of the leaf)
isolated from tobacco mosaic virus-infected N. tabacum cv. Xanthi-nc leaves. However, these isolated
protoplasts were capable of synthesizing and selectively secreting the PR1 proteins. Using monoclonal
antibodies for immunofluorescence microscopy, we localized these proteins to the extracellular spaces
predominantly in regions adjacent to viral lesions as well as in xylem elements of infected leaves.
