Effect of P. indica on the root architecture of A. thaliana seedlings grown for 12 days on PNM media under long day light condition (50 ± 15 µmol m⁻² sec⁻¹). (A) Root architecture of Arabidopsis seedlings grown on PNM media with and without cellophane. (B) Microscopical view of the roots' network in control and P. indica-treated seedlings (+ P. indica) grown on PNM plates covered with cellophane. Pictures were from the GiaRoot software. (C) SEM images of control and P. indica-colonized Arabidopsis roots after 10 days of colonization. For statistics, cf. Materials and Methods.
