a The overall display of the symbiosis relationship between maize roots and AM fungi. b Detailed display of symbiosis relationship between maize roots and AM fungi. The purple pentagram represents the hypha, the red pentagram represents vesicle, yellow pentagram shows mature arbuscular, and orange pentagram indicates degraded arbuscular. c Expression patterns of ZmRboh genes in root samples in response to arbuscular mycorrhizal fungi. Color scale at the right represents log2-transformed fold-change values. The expression level of each Rboh genes can be estimated based on the scale to the right. Purple indicates high expression level; white indicates medium expression level; and green indicates low expression level. Dpi, day post inoculation. d qRT-PCR analysis of ZmRboh genes in root samples in response to Arbuscular Mycorrhizal symbiosis. Maize was grown in nutrient solution containing 50 μM Pi and sampled 60 days after treatment initiation. Data are presented as the means SD (n = 3 biological replicates). Asterisks indicate significant differences compared to the control. Student’s t-test, *, P < 0.05; **, P < 0.01; ***, P < 0.001. Bars: (a, b) 100 μm
