Extended Data Fig. 8: Putative archaeal alkB consistently abundant at surface and DCM stations.

a, Maximum-likelihood phylogenetic analysis for each station with scale bar of substitutions per site. Clade designations as follows: green (alkane-1-monoxygenase representatives and related Tara hits), blue (xylene monooxygenase representative and related Tara hits), yellow (putative Marine Group II/III archaeal monooxygenase). See Supplementary Data 2 for homology search results for putative MG II/III monooxygenase hits. Trees <27 unknown Tara sequences are out-grouped with delta-9 fatty acid desaturases, whereas trees with >27 unknown Tara sequences are left unrooted. b, Meta-data for each Tara station and abundance of unique hits derived from read-mapping. % Coverage indicates the fraction of reads that map to genes within each clade (xylene monooxygenase, alkB, or archaeal monooxygenase) over the total reads mapped to all alkB-like, xylene-like, and archaeal monooxygenases found at each station.
