  1. All data are presented as mean ± SD (n = 3). The same letters with in a column are significantly different (Tukey’s Test p ≤ 0.05). “a” indicates the statistical difference between the control and treated plants; “b” indicates the statistical difference between the pathogen infested and treated plants
  2. C control, P pathogen, CC+P culture cells and pathogen, CS + P culture supernatant and pathogen, CE + P culture extract and pathogen, CC culture cells, CS culture supernatant, CE culture extract
  3. 1Values indicate percentage increase over pathogen infested plants
  4. 2Values indicate percentage increase over control plants
