Title

G. P. Bolwell Journal of Experimental Botany 2002. doi:10.1093/jexbot/53.372.1367
Other claims from this paper (7)
- Observation NADPH oxidases have been implicated in oxidative burst systems and characterized.
- Mechanism An exocellular peroxidase appears to be the main ROS source in elicited French bean cells.
- Observation The candidate substrate becomes available minutes after elicitation and is extractable.
- Intervention effect Palmitate and stearate stimulated hydrogen peroxide production without oxylipin production.
- Observation The peroxidase isoform occurs at hydrogen peroxide production sites in infection papillae alongside cross-linked wall proteins, callose and callose synthase.
- Observation Cloned French bean peroxidase expressed in Pichia catalysed oxidation with the kinetics of the purified enzyme.
- Intervention effect Arabidopsis transformed with French bean peroxidase in antisense orientation became highly susceptible to bacterial and fungal pathogens.
