Effect of extracts of KUDC1013 on soft rot symptoms on tobacco leaves. Roots of seedlings were inoculated with Sterile distilled water (SDW) (A), 10% Dimethylsulfoxide (DMSO) (B), 0.5 mM Benzothiadiazole (BTH) (C), n-Hexane (D), Ethyl acetate (E), n-Butanol (F), and Aqueous (G) extracts. SDW and 10% DMSO were used as negative controls and BTH as positive control. One week after treatment, plant leaves were challenges with soft rot pathogen, as described in Materials and Methods. Photographs were taken 24 h after inoculation with P. carotovorum. The photographs are representative of three independent experiments with at least 72 seedlings per treatment.
