Fig. 1: Secondary metabolism of biocrust.
From: Long-read metagenomics of soil communities reveals phylum-specific secondary metabolite dynamics
a Photos of Biocrusts taken near Canyonlands National Park (Moab, UT) with the biological soil crust inlay showing the characteristic green coloration. Photo credit Trent R. Northen. b Taxonomic composition of the metagenomes based on exact sequence variants (ESVs) of 16 S rRNA genes across sequencing platforms. Relative abundances were calculated after assigning taxonomy against the SILVA reference database. c Left panel shows the number of Biosynthetic Gene Clusters (BGCs) recovered from each assembly, arranged from shortest to longest. Right panel shows the cumulative length of BGCs recovered from each metagenome in Megabases (Mb). d Taxonomic distribution of BGCs in megabase pairs (Mb) at the phylum or class level. e BGCs longer than 5 kb from each major class of secondary metabolism, colored by putative phylum-level assignments.
