Fig. 5: Potential functional capabilities and acquisition strategies of soil microbial communities.

The three graphs show results from PICRUSt2 comparing 1-year to 10-year drought. This revealed potential enrichment or depletion (respectively, positive and negative Log2 fold changes) of many functional traits of the microbial community related to important functions in response to drought history. The left graph shows the mean proportion of level 2 KEGG Orthologies within the bacterial community for the 1-year and 10-year treatments. Colour indicates soil treatment (1 year = light blue, 10 years = blue). Red asterisks indicate significant differential abundances of the overall group. The middle graphs represent the number of functions that were enriched (black circles) or depleted (purple circles) using DESeq2 (respectively, positive and negative Log2 fold changes). The right graph represents the microbial groups (bubble size represents bigger or smaller frequency of ASVs in each group of function within each phylum) contributing to enriched or depleted functions (respectively, positive or negative). Individual phylum colour are described in the figure.
