Evidence for the requirement of extracellular protease in the pathogenic interaction of Pyrenopeziza brassicae with oilseed rape

1991-02-01

Abstract excerpt

Using a detached cotyledon test for pathogenicity, a UV-induced, non-pathogenic mutant of Pyrenopeziza brassicae was isolated which was also deficient in extracellular protease production in vitro. The proteolytic activity in the wild type was apparently due to a single cysteine protease with a mol. wt of 34 k, a temperature optimum of 40 degrees C and a pH optimum of 8. When the mutant was crossed with a wild-typ...
