Pi protects Arabidopsis seedlings from Vd infection. (A) Fresh weights of seedlings after 10, 14 and 21 days of co-cultivation or mock-treatments on Petri dishes. The seedlings were exposed to either Pi or Vd alone or in combination as described in the Methods and Additional file 1: Figure S1. C: seedlings treated without fungi; Vd: seedlings treated with Vd; Pi: seedlings treated with Pi; 1P2V: seedlings first treated with Pi for 4 days followed by Vd; 1V2P: vice-versa as 1P2V. n.d: no detectable (seedlings were dead, no fresh weight could be determined). The data are based on 3 independent experiments with 16 seedlings each. Bars represent SDs. Asterisks indicate significant differences, as determined by ANOVA (* P ≤ 0.05; ** P ≤ 0.01; *** P ≤ 0.001). (B) The phenotype of typical seedlings on 21st day. (C) PDI for seedlings exposed to Vd. For treatments, cf. Methods and Additional file 1: Figure S1. The data are based on 3 independent experiments with 16 seedlings each. Bars represent SDs.
