Fig. 4: GO enrichment analysis of enriched Actinobacterial metagenome-assembled genomes (MAGs) at the peak of drought in the rhizosphere.

GO enrichment analysis for all COGs showing enrichment within genomes of enriched Actinobacterial MAGs (n = 10) as compared with nonenriched Actinobacterial MAGs (n = 5) under drought for rhizosphere at time point 8 (TP8). The values on the x-axis indicate the fold enrichment ratio of the relative percentages of COGs upregulated under drought in each category relative to the total relative percentage of COGs in the corresponding category within the entire dataset. Solid (filled) circles indicate categories for which the enrichment had a p-value < 0.05 in a one-sided hypergeometric test and empty circles indicate categories with p values > 0.05.
