Characterisation of a PR-1: Luciferase transgenic line deployed to uncover novel defence-related Arabidopsis mutants by luciferase imaging In order to identify components of the defence signalling network that may contribute to the establishment of disease resistance, we generated a novel PR-1::Luciferase transgenic line which was deployed in an imaging based screen to uncover novel defence-related mutants. Approximately, 5000 ethylmethane sulfonate (EMS) lines and 30 000 activation tagged lines were generated and screened for enhanced LUC activity via ultra low light imaging.
