Phenotype differences between maize seedlings colonized and uncolonized by P. indica. (A) Typical root architecture of maize 15 days after inoculation (left) or uninoculation (B, right) with P. indica, P. indica chlamydospores on maize tap root inspected by Trypan blue staining (white arrow) at 15 DAI under microscope (Leica DM5000 B, Germany), with scale bar=20 μm. (C, D) Typical shoot and root phenotype of maize 15 days after inoculation (right) or uninoculation (left) with P. indica, with scale bar=5 cm. (E-H): Length of tap root (E), fresh weight (FW) of roots (F), dry weight (DW) of roots (G), and leaf area (H) of maize seedlings inoculated or uninoculated with P. indica under drought stress, while uninoculation and not-drought stress-exposed seedlings were used as control. All experiments were performed with at least 3 replications. Statistically significant differences are labeled with letters (p< 0.05, two-wayfactor ANOVAone way ANOVA).
