Fig. 5: Expression and abundance of bacterial photosynthesis genes.

Protochlorophyllide reductase (DPOR) and chlorophyllide reductase (COR) reads in a metatranscriptomes, (b) metagenomes, and c mapped to the Limnohabitans metagenome-assembled genome (MAG) 5. In a, b, DPOR (red) and COR (blue) transcripts (a) and genes (b) are shown within different experiments and experimental treatments. Abbreviations denote the experiment (e.g., UC4), the sampling time point, and the treatment (control, addition of the methanogenesis inhibitor 2-bromoethanesulphonate [BES], or high light intensity). In c, the Limnohabitans MAG 5 is shown in circular form, and the number of reads mapping to genes within the MAG are indicated by color intensity. Different experiments and treatments are shown in different colors, with the LG6 experiment in red, L7 in orange, the UC4 control in aqua, the UC4 BES treatment in light blue, and the UC4 high light treatment in dark blue. Locations of DPOR and COR (and associated photosynthesis genes) within the MAG are indicated. Source data are provided as a Source Data file.
