Figure 4
Box-and-whisker plots of the peak number in each growth condition. Statistical analysis indicates that when the fungus and the plant are both grown in high Pi (EHP-MHP - exudate high phosphate/medium high phosphate) or low Pi (ELP-MLP - exudate low phosphate/medium low phosphate), the observed Ca2+spiking patterns are significantly different from the two intermediate conditions (ELP-MHP; EHP-MLP). N ≥ 19 responding cells per experiment; The figure shows median peak numbers (black lines), 25% to 75% quartiles (boxes) and ranges (whiskers); letters indicate P value < 0.05 using nonparametric analysis of variance Kruskal-Wallis test with Dunn’s multiple comparison post test. Open circles represent extreme values.
