Nicotiana accessions used in this study and their responses to AvrB and AvrRpm1.

A (+) sign indicates that leaves expressing a given effector gave a stronger response than leaves expressing GUS, while a (-) sign indicates there was no difference between leaves expressing an effector and those expressing GUS. The observed morphologies in response to Agrobacterium-mediated transformation were leaf browning (b), shininess on the abaxial surface (s), leaf collapse (lc), and no response (nr). See Figure S1 for photographs of phenotypes. Each plant species/accession was tested at least 3 times with similar results.Nicotiana accessions used in this study and their responses to AvrB and AvrRpm1.
