Mechanism of cell destructive action of organophosphorus insecticide phosalone in Clamydomonas reinhardtii algal cells

Stationary phase Clamydomonas reinhardtii cells were exposed to phosalone for 2 h and then either maintained in phosalone or washed and resuspended. No cell loss was seen in the 2 h treatment period for either regime, but both suffered about 50 per cent cell loss in the next 22 h. Alkaline phosphata...

Description
Summary:Stationary phase Clamydomonas reinhardtii cells were exposed to phosalone for 2 h and then either maintained in phosalone or washed and resuspended. No cell loss was seen in the 2 h treatment period for either regime, but both suffered about 50 per cent cell loss in the next 22 h. Alkaline phosphatase activity in the cells began to decrease after about 30 minutes post-treatment and cell protein leakage began after about two and a half hours. Cell membrane lesions were apparently produced during the next 2 to 3 h permitting protein leakage and resulting in cell destruction.
