FIG 5.

Changes in AAP bacterial communities during the experiment based on the pufM amplicons. (A) Nonmetric multidimensional scaling plot showing changes in beta-diversity based on Bray-Curtis distances; (B) heatmap showing changes in the relative abundance of reads of 50 most abundant ASVs. Blue represents a low and red represents a high contribution of an ASV. Clustering was done using the unweighted pair group method with arithmetic mean (UPGMA) method on Bray-Curtis distances calculated from the percent data. The values were centered and scaled by removing the mean and then dividing by the standard deviations to facilitate visualization of both abundant and rare ASVs. Bacterial phyla are color-coded as indicated in the legend. LL, low light treatment; OL, optimum light treatment; OL-Inh, optimum light with inhibitor treatment. Numbers after the treatment abbreviations indicate time points; the A to C suffixes indicate replicates.
