We defined genes regulated by infection with each strain and then subdivided these genes into NAM-sensitive (genes differentially expressed in Col-0 without NAM but not in the presence of NAM), EDS1-dependent (genes differentially expressed in Col-0 but not in eds1), and TNL RPS4-dependent genes (genes differentially expressed in Col-0 infected with Pst DC3000 AvrRps4 but not with Pst DC3000 EV). The gene discussed is RPS2; the disease is infection.
