Result:(1)Tau prevented neurons against Mn toxicity of low and middle concentrations. The ideal conditions can reach upon 4. 5 mM Tau added just, nearly no apoptosis cells could be detected.(2)The percentages of apoptosis intogether were lower than those in Mn just , being concentration-dependent relations with Taurine levels.(3)Mn induced DNA damage of neurons with dose-depedent, The higher of Mn concentration, the lengther of the comet tail and the higher percent comet-like cells. Tau incubated could weaken significantly the lesions of Mn towards DNA on the degree.

The results indicated that the accumulation of Mn in the cell wall (accumulation rate as high as 36.34%) and the vacuole of the leaves (accumulation rate as high as 65.64%) might be one of the mechanisms of tolerance and hyperaccumulation of Polygonum hydropiper to Mn. Most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. The content of chlorophyll a did not change under different Mn concentration treatments except that its content decreased remarkably when Mn concentration was 8000μmol/L in solutions. The membranes were not banned by Mn when its concentration was less than 5000μmol/L in solutions; Under different Mn concentrations of Mn, the content of their soluble proteins of leaves had changed at some stage. The activity of SOD and POD were gradually improved with the increasing of Mn concentration, which could eliminate activated oxygen free radical, This might be the other physiological mechanism of tolerance and hyperaccumulation of Polygonum hydropiper responding to Mn.
