AHL production by D. marina. (a) AHL production of extracts from D. marina spotted on AT medium seeded with X-gal and AHL reporter strain Agrobacterium tumefaciens KYC55/pJZ372, pJZ384, and pJZ410. (b) Time course of AHL production as assessed by β-galactosidase assays of reporter strain mixed with extracts from D. marina. Miller units (left vertical axis) are indicated with a solid square and solid line and the growth (OD600) (right vertical axis) is indicated by dotted line and open squares.
