(a) Density plots of Shannon’s Diversity in drought (yellow) and control (samples) for each combination of sample type (soil, rhizosphere, root) and time point (early, late). Asterisks indicate drought treatment groups that were significantly different from the respective control group by anlaysis of variance (ANOVA) and Tukey's post hoc tests. (b) Principal coordinate plot for all samples generated using the Bray–Curtis distance; samples are colored for each combination of sample type and treatment. (c) Percent of variance explained by each factor as determined by canonical analysis of principal coordinates (CAPS) using the Bray–Curtis distance for remaining three experimental factors (species, time point and replicate), performed separately for each pairwise combination of sample type and treatment. The y-axis indicates the fraction of variance explained, and the shade of the bar indicates the significance. Error bars indicate a 95% bootstrap confidence interval around each fraction of variance explained.
