Effect of different light intensities on A. thaliana growth in the presence/absence of P. indica. (A) Shoot fresh weights (left) and % weight promotion by P. indica (right) under continuous light and different light intensities (25–110 µmol m⁻² sec⁻¹). Seedlings were grown for 10 days with/without P. indica. (B) Fluorescence parameters [Y (effective quantum yield of photosystem II), Fs/Fm and NPQ] in Arabidopsis shoots after 10 days co-cultivation with P. indica under continuous light (25 ± 5, 50 ± 15 and 110 ± 10 µmol m⁻² sec⁻¹). All results are based on 3 independent experiments with 10 individual seedlings. Bars represent SE. Asterisks indicate significant differences (relative to its own control) as determined by t-test (* P ≤ 0.05; ** P ≤ 0.01; *** P ≤ 0.001).
