Fig. 2: Cell cartoon based on the genome annotations of 11 hot-spring comammox Nitrospira MAGs.

Shown are pathways and genes involved in metabolisms of carbon, hydrogen, nitrogen and sulfur, as well as respiration, electron transport, and stress defense. Metabolic modules are indicated by distinct color schemes. The presence of metabolism types across 11 hot spring comammox Nitrospira MAGs from this study is indicated as follows: dark blue solid circles represent all 11 MAGs; light blue solid circles represent 5 to 10 MAGs; light blue hollow circles represent 1 to 4 MAGs; and gray solid circles represent 0 MAGs. The numbering scheme associated with the shown pathways is given in Supplementary Dataset 2. Respiratory chain complexes are labelled by Roman numerals.
