Copper-treated soybean ( Glycine max ) seedling shows significant inhibition in soybean root growth, and enhancement in POD activity. Cu is an efficient catalyst in the formation of several reactive oxygen species and free radical. The increase in POD activity induced by Cu might remove excess hydrogen peroxide serving a detoxifying role during Cu-treatment. The increase of cationic ( pI 8.9, pI 8.3 and pI 7.7 ) PODs and anionic ( pI 6.5, pI 5.6 and pI 4.4 ) PODs activities is accompanied by a rise of lignin contents in Cu-treated tissues. We suggest that the increase in cationic ( pI 8.9, pI 8.3 and pI 7.7 ) and anionic ( pI 6.5, pI 5.6 and pI 4.4 ) PODs induced by Cu is responsible for lignin synthesis in soybean roots during Cu treatment.
