e0“Mutagenized avirulent mutants (AV) of Geotrichum candidum and mutants of reduced virulence had lower polygalacturonase (PG), cellulase (Cx), and phosphatidase (PT) activity values than the virulent wild-type strain (G.c. met-1).”

Other claims from this paper (5)
- Observation Some avirulent mutants yielded reduced-virulence revertants after mutagenesis.
- Observation Reduced-virulence revertants had increased PG, cellulase and phosphatidase activity, but levels remained below the wild type.
- Observation PG, cellulase, phosphatidase and pectin methylesterase activities were higher in rotted fruit than healthy fruit.
- Observation In vitro Geotrichum candidum produced PG, cellulase and phosphatidase, but no PME or pectin transeliminases.
- Observation No heterokaryons formed among the tested Geotrichum candidum and Endomyces geotrichum mutants.
