Figure 6.

(A) Shoot fresh weights (left) and % weight promotion by P. indica (right) in A. thaliana leaves of seedling with/without P. indica and 10 days after leaf infection with A. brassicae. The seedlings were grown under long day light condition (50 ± 15 µmol m⁻² sec⁻¹). (B) H₂O₂ levels in leaves of Arabidopsis seedlings after infection with A. brassicae in the presence/absence of P. indica after 10 days. (C) Stomata closure after Alternaria leaf infection of colonized and uncolonized seedlings after 10 days. (D) Relative gray values of the images (biophoton records) of Alternaria-infected Arabidopsis leaves treated with/without P. indica. For statistics, cf. Materials and Methods.
