Extended Data Fig. 2: Expression of genes in enriched AMX1 at different days during the reactor operation.

Gene expression levels, quantified as Log2(TPM + 1), are shown for metatranscriptomic samples collected at key time points: under dark conditions on day 60 and under light conditions on days 200 and 450. Rows denote genes categorized by function, including light sensing and adaptation, nitrogen metabolism, electron transfer, and cyanate assimilation. The gene encoding hydrazine synthase subunit C (hzsC) was not detected in the AMX1 genome, likely due to the incompleteness of the recovered MAG. For each condition, TPM values represent the mean ± standard deviation derived from three biological replicates.
