EDS1, PAD4, and NDR1 Are Required for cpr22-Mediated Resistance to P. syringae pv maculicola ES4326 but Not for SA Accumulation.

(A) After infiltration with P. syringae pv maculicola ES4326, bacterial growth was monitored in the leaves of 3-week-old wild-type Ws and Col-0 plants, cpr22/CPR22, eds1-1, pad4-1, and ndr1-1 single mutants, and cpr22 heterozygous, ndr1-1, pad4-1, or eds1-1 homozygous double mutant plants by collecting three leaf discs at 0 d after inoculation (open bars) and 3 d after inoculation (closed bars). Colony-forming units (cfu) are expressed ±sd and represent averages of four independent samples.

(B) Total SA levels were assayed in leaves of 3-week-old, soil-grown wild-type Ws and Col-0 plants, cpr22/CPR22 (cpr22), eds1-1, pad4-1, and ndr1-1 single mutants, and cpr22 heterozygous, ndr1-1, pad4-1, or eds1-1 homozygous double mutant plants. The values are presented in micrograms per gram fresh weight (FW) and represent averages ± sd of three samples consisting of leaves from three plants per line.
