Schematic representation of genetic organization of the GAD genes (i.e. regulator gadR, glutamate/GABA antiporter gadC, glutamate decarboxylase gadB, and two promoters PgadR and PgadCB) in lactococci: ∆ (blue) deletions observed in all L. cremoris species relative to L. lactis, ∆ (red) deletion or ▼ (red) insertion only observed in L. cremoris species with the cremoris phenotype, ▼ (grey) insertion site for the IS981 element in L. lactis S642.
