campestris pv. incanae (Xci). Xci is the causal agent of black rot of garden stock and closely related to Xcc. PCR using pncB_fw1 and Xcr_rv1, or pncB_2 and Xcr_rv2, amplified DNA fragments only in Xcr. Multiplex PCR analysis easily distinguished Xcc and Xcr from bacterial colonies isolated on growth media and detected the pathogen in symptomatic leaves. Multiplex nested PCR detected the contamination of one seed with Xcc and/or Xcr infection from 1000 seeds. Therefore, the PCR primers designed in this study therefore helped de
