Halocin genes are almost universally expressed at the transition between exponential and stationary phases of growth; the only exception is halocin H1, which is induced during exponential phase.
Os xenes de halocinas exprésanse case universalmente na transición entre as fases de crecemento expoñencial e estacionaria; a única excepción é a halocina H1, que é inducida durante a fase expoñencial.
