Phenotypes & Variants

Disruption phenotype

Shortens transitional period (when fingers and migrating slugs assess their environment to determine the appropriateness of that environment for culmination and fruiting body formation) of 1 to 2 hours and rarely forms slugs under standard conditions of development. Gives a slightly enhanced growth rate in axenic cultures.

PTM/Processing
