After the cells were treated by high concentration toxin for 4d, the content of nitrate-nitrogen in cells were lower markedly than the contrast, after the cells were treated by middle and low concentration toxin for 7d, the content of nitrate-nitrogen in cells were lowered. 3 groups of toxin treating all lowered the total phosphorus content. At the end of test, the phosphorus contently of low, middle, high concentration treating groups were 74.98%, 76.47% and 84.00% of the contrast respectively. The ACP activity of 3 treating groups compared with the contrast appeared the tendency of first lowering then raising.

To investigate the expression, location and function, long distance PCR was used to expand the targets containing open reading frame. The expressive vectors of prokaryotic and eukaryotic cells were constructed after product purification and connecting with vectors. The prokayotic vectors were induced to express the protein by IPTG and the protein was seen by denaturalization PAG electrophoresis and dyeing. The eukayotic expressive vectors were transfected into culture cells and the protein was found in the nulceolus under the observation of the confocal microscope. The transfected cells were chosen by the geneticin (G418). The cell cyele was examined by flow cytometer and the cell numbers were reduced obviously in the stage of G〓-G〓 and G〓-M, but increased distinguishably in the S stage.
