| Popis: | High levels of both endo - and exo -chitinase activity were detected in two virulent isolates but not in one avirulent isolate of Nomuraea rileyi . The greatest difference in chitinolytic activity occurred at germination when endo -chitinase activity in the virulent isolates was 10 to 17 times higher than that in the avirulent isolate, and exo -chitinase activity of the virulent isolates was 15 to 18 times higher than that of the avirulent isolate. Both endo - and exo -chitinase activity were simultaneously expressed in all isolates. |
