Figure 4: Time course of vegetative amoeba proliferation in Burkholderia xenovorans (Bx) supernatants.
From: Social amoeba farmers carry defensive symbionts to protect and privatize their crops
We tested 10 clones (5 farmers and 5 non-farmers) for amoeba proliferation in Bx supernatants prepared from 5 individually isolated farmer-associated strains. We collected data for each clone with each supernatant every hour for 5 h. Harm to non-farmer amoebae increased as exposure time to Bx supernatants increased. Conversely, benefit to farmer amoebae increased with time under the same conditions. Error bars equal s.e.m.
