Fig. 4. Seasonally resolved transcription of genes involved in the nitrogen and carbon metabolism of AOA-LC4 at 85 m depth.

As reference housekeeping genes, the two highest transcribed genes encoding either proteins of the large (rpl12, rpl21e) or small ribosomal subunit (rps11, rps15) are shown at the bottom. Transcription values are represented as log₁₀-transformed mean FPKM (fragments per kilobase of transcripts per million mapped reads) values for every time point. Values represent the mean of three replicates, except for the February and April samples, where only two replicates could by analyzed. No transcription of a specific gene is indicated in white. Putatively annotated genes are given in brackets; gene duplicates were consecutively numbered.
