Dominant Negative Effect of R2M1 and R2M2 Measured by a Transient Expression Assay.

The RPS2 wild-type construct was cobombarded with a 10-fold excess of the indicated RPS2 derivatives or the vector as competitors in a transient expression assay to measure the response to avrRpt2. The decrease in GUS activity with the vector competitor control was set to 0% inhibition, and the GUS activity observed in the absence of RPS2 (no response) was set to 100% inhibition. The error bars indicate the standard deviation.
