Protoplast Cell Death Assay to Study Magnaporthe oryzae AVR Gene Function in Rice
We describe a protocol for transient gene expression in rice protoplasts and its application to the study of Magnaporthe oryzae avirulence (AVR) gene function. In this assay the gene encoding the firefly luciferase protein is transfected into rice protoplasts by electroporation together with the candidate AVR genes. The luminescence can then be used to assess the viability of rice protoplasts. The hypersensitive response (HR) caused by the interaction between M. oryzae AVR and rice R genes can subsequently be monitored by recording the decrease in luminescence from the transfected cells.
