Fig. 2From: Genomic insights into cryptic cycles of microbial hydrocarbon production and degradation in contiguous freshwater and marine microbiomesMetabolic potential for hydrocarbon production in Lake A. a Number of genes involved in hydrocarbon production in the metagenomes throughout the water column. Aldehyde decarbonylase in gray represents the cumulative alkane production genes (ADO and FAD). b Phylogenetic tree of hydrocarbon-producing proteins detected in the metagenomes (in black) including binned and unbinned sequences. Only nonredundant sequences were represented in the tree. Sequences in gray were recovered from NCBI database. Blue dots indicate bootstrap values higher than 0.8Back to article page
