Multigenerational exposure of the microalga Tetraselmis suecica to diuron leads to spontaneous long-term strain adaptation

Results of second exposure to diuron revealed that the adaptation of strain D3 had persisted after 12 months of depuration, as no growth impairment was observed. This study demonstrates the possible appearance of stable diuron resistance in microalgae in cases of strong, multigenerational chronic exposure to this herbicide in polluted environments.
