The significant root growth inhibition in zinc-treated soybean (Glycine max) seedling correlated with the increase of PODs and laccases activity. The increase of the activities of PODs (pI 8.3, pI 7.7, pI 4.8, pI 4.4 and pI 3.7) and laccases (pI 9.4, pI 8.3, pI 7.4, and pI 3.7) are accompanied by a rise of lignin contents in Zn-treated tissues. Our results suggested that laccases work during the early stage of Zn treatment. Laccases and peroxidases work cooperatively in lignin synthesis when the time of Zn treatment was prolonged.
