R. S      Anandaraj. M      Sarma. Y. R       Indian Phytopathology ;  2001  [Vol.54]  Pages:23-28 Abstract The activities of phenylalanine ammonia lyase (PAL) and 61,3 glucanase in both leaf and root tissues of three black pepper varieties (tolerant P24; and susceptible Panniyur and Subhakara) were determined in healthy and Phytophthora capsici infected tissues. Infection generally enhanced both of these enzyme activities . SDS-PAGE study revealed the induction of PR-proteins in the infected tissues. Western blotting with anti-tobacco 61,3 glucanase antibody confirmed the presence of these isoforms in the leaf extract . Among the three varieties studied, the Phytophthora tolerant P24 expressed higher rate of these defense-related enzymes/proteins. Keywords pal 61,3 glucanase pr-proteins p. capsici black pepper
