Responses of tobacco leaves to TMV after treatment with HpaXpm or B-HpaXpm. Leaves were inoculated with Tobacco mosaic virus (TMV) 12 h after spraying with HpaXpm or B-HpaXpm; leaves sprayed with PBS acted as a negative control and leaves inoculated with Hpa1Xoo acted as a positive control. Treated leaves were photographed 5 days after inoculation. The disease severity of leaves was determined by comparing the ratio of the lesion area to the whole leaf area. Quantitative data are given as mean values ± SEM. Different lowercase letters above the bar graphs indicate significant differences in multiple comparisons of data from the different proteins; P < 0.05; n = 15 leaves from 3 independent experiments each involving 5 leaves. The mean reduction in disease severity of leaves treated with HpaXpm, B-HpaXpm, or Hpa1Xoo, relative to those treated with PBS, is shown in red
