Supplementary Material 1: Fig. S1. Phenotypic evaluation of mycorrhizal colonization after 4 weeks (early phase) in L. japonicus plants inoculated with the AM fungus R. irregularis after repeated irrigations with PAW 10’ or H2O only. Fig. S2. Viability of L. japonicus cell suspension cultures treated for either 1 h (A) or 48 h (B) with PAW 10’. Fig. S3. Inorganic phosphate (Pi) content in leaves of non-mycorrhizal L. japonicus seedlings after repeated irrigations with PAW 5’, PAW 10’ or H2O only. Fig. S4. Quantification of nitrogen, carbon and sulphur content in dry shoots of non-mycorrhizal L. japonicus seedlings after repeated irrigations with PAW 5’, PAW 10’ or H2O only. Fig. S5.
