FIGURE 2.

Typical growth inhibition of S. solfataricus on plates due to infectious virus. Lawns of S. solfataricus strain GΘ were prepared as in Stedman et al. (2003). Two microliters of supernatant from cultures transformed with either (A) SSV-ΔVP2 or (B) SSV-Δd244 were placed on the lawns where indicated. Δ indicates where SSV-ΔVP2 was spotted, ΔD where SSV-Δd244 was spotted. P indicates SSV-WT spotted as a positive control. T or Tx indicates 2 μL of 0.01% Triton X-100 spotted as a control for lawn growth.
