e0“H2O2 and the irreversible catalase inhibitor 3-amino-1,2,4-triazole (3-AT) were found to be weak inducers of PR-1a expression (relative to SA) in wild-type tobacco but were unable to induce PR-1a in SH-L plants”

- Intervention effect Pathogen challenge induced PR-1a in wild-type and PR-1a-GUS tobacco.
- Intervention effect SA induced PR-1a in wild-type and reporter tobacco.
- Intervention effect INA induced PR-1a in wild-type and reporter tobacco.
- Intervention effect SA failed to induce PR-1a in SH-L tobacco.
- Intervention effect INA induced PR-1a in SH-L tobacco.
- Intervention effect 3-AT weakly induced PR-1a in wild-type tobacco relative to SA.
- Intervention effect H2O2 did not induce PR-1a in SH-L tobacco.
- Intervention effect 3-AT did not induce PR-1a in SH-L tobacco.
- Mechanism The effects of peroxide and 3-AT were interpreted as depending on SA accumulation.
- Intervention effect Catalase activity showed no significant change after P. syringae infection.
- Intervention effect In vitro SA inhibited tobacco catalase only after preincubation and above 250 microM.
- Intervention effect Leaf disks given 1 mM SA accumulated SA and efficiently induced PR-1a without apparent catalase inhibition.
- Intervention effect SA-treated leaf disks showed no apparent catalase inhibition.
- Intervention effect PR-1a and AoPR-1 were relatively insensitive to 3-AT.
