Abstract
We have screened hypersensitive responses of 18 cultivars of Nicotiana tabacum to Xanthomonas campestris pv. campestris. TC500 cultivar produced the most strong hypersensitive response (HR) to Xanthomonas campestris pv. campestris. By NTG mutagenesis, nonhypersensitive mutants (XHN 514-774, XHN 620-831) were generated, which does not induce hypersensitive response on tobacco leaves (Nicotiana tabacum cv. TC500). Also nonpathogenic mutant (XPN 1001), which does not incite any of the black rot symptoms on leaves was generated. We observed that HR mutants were still pathogenic on cabbage leaves producing black rot symptoms and nonpathogenic mutant induced HR in tobacco leaves. The inplanta growth of wild type and HR mutants were examined for up to 120 hrs after inoculation : population of wild type strain increased to
