Fig. 2: Phosphonate gene and genome count with taxonomic distribution.
From: Global and seasonal variation of marine phosphonate metabolism

Number of sequences and genomes collected for study (A, D, G) with distribution of class-level taxa for all redundant sequences (B, E, H) and marine redundant (C, F, I) sequences. Results are shown for selected genes representing phosphonate (A–C) production, (D–F) substrate-specific catabolism, and (G–I) broad-specificity catabolism. The taxa shown are the 15 classes with the highest representation across all databases.
