Effect of insertion of Synechocystis DNA in B. subtilis on the progression of engulfment. The symbols indicate bacteria that had reached a given stage of engulfment (and may have progressed beyond it): diamonds, stage IIi; circles, stage IIii; triangles, stage IIiii; squares, stage III. Values are percentages of the maximum number that reached stage IIi. (A) Strain SL14360, which contains no Synechocystis DNA; for each point, at least 200 organisms were scored. (B and C) Independent experiments with strain SL14378, which contains 2.3 Mb Synechocystis DNA. (B) At least 100 organisms were scored for each point (except for 5 h, for which 89 were scored). (C) At least 200 organisms were scored for each point (except for 5 and 5.5 h, for which at least 140 organisms were scored).
