Fig. 5: Functional potential of microbial communities from root-associated edaphic niches of the Namib Desert.

From: The plant rhizosheath–root niche is an edaphic “mini-oasis” in hyperarid deserts with enhanced microbial competition

a Heatmap showing the relative normalized abundances of metabolic marker genes from the metagenome assemblies in rhizosheath (RS), rhizosphere (RH) and non-vegetated (NV) soil. Relative abundances are calculated by first normalizing by sequencing depth and then scaling against the highest proportion for each marker gene; genes within the PGP categories biofertilization, biopromotion and bioprotection (abiotic and biotic stresses), along with genes involved in biotic competition, are used in this analysis. b Relationship between the copies of PGP/biotic competition genes (x-axis) and the number of microbial species presenting these genes (y-axis) is visualized in NV, RH and RS. c Number of biosynthetic gene clusters (BGCs) detected across RS, RH and NV soil metagenomes; antibiotic-encoding BGCs are indicate in black, while the remaining BGCs in gray.
