  2. 2Data represent mean ± SE (n = 5). Asterisks indicate statistically significant differences between CSA and CSA-Pi9 in each field (*P < 0.05, **P < 0.01, ***P < 0.001; Student's t-test). n.a.: not applicable (all plants dead)
  3. 3Data represent the mean of five measurements. n.a.: not applicable (all plants died)
