Abstract:

In this paper，various of reactive oxygen species were respectively added to the fermentation medium on the 4 d. After a certain time，the effection of different reactive oxygen species on laccase synthesis of white-rot fungus，was evaluated by measuring biomass and laccase activity. And then this effection was further investigated by the method of native PAGE. The experiment results show that reactive oxygen species can regulate laccase synthesis of white-rot fungus via redox regulation in cellular signaling. In addition，superoxide anion inhibits laccase synthesis，but hydrogen peroxide and hydroxyl radical promote it obviously. These results are very important for researching biosynthesis regulation of laccase and interaction between plant and pathogen，which can be used for biological protection.
