Abstract

The increased endopeptidase activity and decreased protein content were found in leaf of wheat seedling under Al 3+ stress or after treatment with H2O2(Fig 1,2). However, the endopeptidase activity was decreased, and the protein content was increased markedly by the treatment of ASA that is a clearing agent for H2O2. These results showed that the increase of endopeptidase activity and the decrease of protein content are likely to the production of H2O2 under Al 3+ stress.
