The significant root inhibition of growth in Cd-treated soybean (Glycine max) seedling correlated with the increase of H2O2 levels, PODs and laccases activity. The increase of the activities of PODs (pI 8.8, pI 7.7, pI 5.2, pI 4.5, pI 4.4 and pI 3.7) and laccases (pI 9.2, pI 8.9 and pI 8.3, pI 5.4, pI 4.2 and pI 3.7) are accompanied by a rise of lignin contents in Cd-treated tissues. Our results suggested that laccases work during the early stage of Cd treatment. Laccases and peroxidases work cooperatively in lignin synthesis when the time of Cd treatment was prolonged.
