FIG 2 .

Identification of S. venezuelae-induced mobility as sliding. S. venezuelae was spotted in the horizontal line in both panels A and B. Pictures were taken at h 48. (A) The mobilization induced by S. venezuelae was observed at up to 2% agar. (B) Different B. subtilis mutants were cultured with S. venezuelae. The mobility of hag mutant was induced but was not observed in either epsH mutants or srfAA mutants. However, when epsH and srfAA were mixed, the mixture was able to mobilize upon challenge with S. venezuelae. Pictures were taken at h 24. Bars, 1 cm.
