Abstract
Hypersensitive response (HR) of rice cells induced by hydrogen peroxide (H2O2), a signal molecule, was investigated. Addition of glucose and glucose oxidase as the H2 O2 -generating system to rice suspension cells resulted in a steady-state production of H2O2 and induction of HR. However, exogenously applied H2O2 was completely degraded by rice cells and no HR was observed. H2O2 generated from the H2O2-generating system could be scavenged by the supplement of catalase. These results indicated that H2O2-induced HR in cultured rice cells occurred in a time-dependent manner. Furthermore, the production of H2O2 was involved in an incompatible bacterial interaction.
