Comparison and characterization of the polyphenoloxidase activity in healthy Maize plants, susceptible and resistant to Ustilago zeae



Comparison and characterization of the polyphenoloxidase activity in healthy Maize plants, susceptible and resistant to Ustilago zeae



Riv. Patol. veg, Pavia, 7: 3, 163-172



The total polyphenoloxidase capacity and the kinetic constants Km and Vmax on several phenolic substrates were determined to compare the polyphenoloxidase activity of vars. susceptible (Marano vicentino) and resistant (Funk's G-77) to U. zeae. Extracts of the latter had a higher oxidizing capacity.
