Effect of impaired ethylene sensitivity or production on development of wilt symptoms in tomato plants infected with Cmm. Six-week-old plants were infected with a Cmm suspension (108 cfu/mL) and examined for development of wilt symptoms during a 20-d period. The percentage of plants showing wilt symptoms was calculated in a group of at least 30 plants for each line. A, The ethylene-insensitive mutant Nr and wild-type Ailsa Craig plants. B, The ethylene-deficient transgenic tomato line ACD and progenitor line UC82B. Data shown are representative of at least two independent experiments for each genetic background.
