FIG. 2.

The G_II alleles of ZK1141 confer the GASP phenotype. Into a 1-day-old culture of the G_I mutant (ZK2552) (●) was inoculated as a 1,000-fold minority of a 1-day-old culture of the G_II strain (ZK2555) (A), the G_I sgaA strain (ZK2561) (B), the G_I sgaB strain (ZK2559) (C), or the G_I sgaC strain (ZK2563) (□) (D). Asterisks indicate that viable counts fell below detectable levels (<10³ CFU/ml). The patterns of GASP takeovers were identical in six replicate mixtures, including ones where the selectable markers were switched between competing strains.
