Summary
Pathogenesis-related (PR) proteins are plant proteins produced in response to infection by pathógens. In tobacco the PR-1 group of proteins are closely associated with virus localization and are found in greatest amount where virus spread is halted. PR proteins are also found in infected plants showing induced resistance to a second infection and are produced in response to a wide range of localized pathogens including bacteria, fungi and viruses. Several chemicals which induce resistance to virus infection and spread also induce the production of PR proteins. PR proteins serologically related to the PR-1 group of proteins in tobacco have been found in a wide range of plants, both monocotyledonous and dicotyledonous. The retention of common antigenic determinants in both subclasses of angiosperms suggests that PR proteins have an important, if as yet undefined, role in the response of plants to pathogens.
