Abstract
Nitric oxide synthase (NOS) activity was detected in tobacco leaf tissues by arginine/citrulline assay procedure. A protein reactive to anti-NOS antibodies was also detected by western blot analysis. Both NOS activity and the NOS immunoreactive protein increased in tobacco leaves during the hypersensitive reaction against Ralstonia solanacearum. Infiltration of a NO-releasing compound into tobacco leaves caused HR-like symptoms. In contrast, infiltration of a NOS inhibitor delayed the onset of the HR. These results indicate that NOS activity is increased in the hypersensitive tissue and that NO may be involved in the HR induction.
