Seventeen major host‐encoded pathogenesis related (PR)‐proteins have been found in intercellular fluids of necrotic virus‐infected soybean leaves. None of them was present in fluids of healthy controls. By native and SDS‐denaturing polyacrylamide gel electrophoresis, ten major acidic PR‐proteins have been identified and classified on the basis of their molecular weight in three groups: group 1 included four proteins of 16–17 Kd; group 2, three proteins of 26 Kd; group 3, three proteins of 32 Kd. Seven PR‐proteins were basic, and were classified in three groups: group 1 included three proteins of 16 Kd; group 2, one protein of 23 Kd; group 3, three proteins of 32 Kd. As found for tobacco and potato, soybean PR‐protein patterns show high number of acidic and basic proteins.
