Production of a pathogenesis related[PR] protein B-1,3-glucanase upon infection was tested in four clones of Hevea. Considerable variability in the B-1,3-glucanase activity of enzyme was observed among different clones during pathogenesis. Increased enzyme activity was found in the tolerant clone (GT 1), while a decrease was observed in the susceptible (RRII 105). Three prominent B-1,3-glucanase isozyme bands were detected by 17.5 per cent PAGE in the tolerant clone ER -
