Abstract

Ten major host-encoded pathogenesis-associated proteins have been found in extracts of intercellular sap of cucumber cotyledons infected with tobacco necrosis virus. By native and two-dimensional SDS-polyacrylamide gel electrophoresis, five major acidic virus-elicited proteins have been identified and classified on the basis of their molecular mass in three groups: group 1 included one protein of 14 kD; group 2, one protein of 28 kD and group 3, three proteins of 37–40 kD. Another five viruselicited proteins were basis, and were again classified in three groups: group 1, included two proteins of 15–16 kD; group 2, two proteins of 22–23 kD; group 3, one protein of 40 kD.
