a) Effect of overexpression of luxR on the growth rate of V. scophthalmi . V. scophthalmi A089_23 (pMMB207) (black triangle) used as control strain vs V. scophthalmi A089_23 (pMMB207 :: luxR) (black square) ; b) Effect of expression of the lactonase aiiA in V. scophthalmi A102. The growth rate was reduced in V. scophthalmi A089_23 overexpressing luxR (black square) compared to the control strain (black triangle) (Figure 1a), while strain A102_6.2 expressing the lactonase (black square) had a longer lag phase with respect to the control strain A102_pACYC (black triangle) (Figure 1b).
