Figure 3From: Automated analysis of calcium spiking profiles with CaSA software: two case studies from root-microbe symbiosesHistogram describing the percentage of actively responding cells for each condition. The percentage of responding cells in the ELP-MLP (exudate low phosphate - medium low phosphate) condition is significantly different from all other treatments. N ≥ 4 roots per experiment; shown is average (± standard deviation [SD]); * indicates P value < 0.05 using unpaired Student t test when the data fit with a normal distribution or Wilcoxon- Mann–Whitney non parametric test in other cases.Back to article page
