Fig. 3From: Biogeographical distribution analysis of hydrocarbon degrading and biosurfactant producing genes suggests that near-equatorial biomes have higher abundance of genes with potential for bioremediationHierarchical clusters obtained from the BioSurfDB functional data through Genesis software, for degradation (a) and biosurfactants (b). Inside the red borders the “equatorial region clusters” can be seen whilst inside the blue borders are the “cold region clusters”. Each column represents a specific pathway and the colour schema for their relative abundances is green for low and red for a high number of blast hitsBack to article page
