IPathogen response (PR) proteins are produced by plants to defend themselves against pathogens. In the absence of pathogens, repressors block the production of PR proteins. Genes encoding PR proteins are regulated indirectly by ethylene, which is released in response to pathogen attack. Receptor molecules on the endoplasmic reticulum bind ethylene and cause the repressors to be nonfunctional.
If you wanted to artifically increase the production of PR molecules, which of the following might work?
