S. venezuelae induces B. subtilis mobilization. (A) Different species of Streptomyces were cultured with B. subtilis to identify patterns of interaction. Streptomyces species were spotted in the horizontal line, and B. subtilis was in the vertical line. Pictures were taken at h 40. (B) S. venezuelae (horizontal spots) induced proximal B. subtilis (vertical spots) to migrate across the agar surface, while this migration was not observed in the distal spots. The right panel presents an enlarged view, highlighting the mobile region inside the dashed box. The picture was taken at h 18. Bars, 1 cm.
