Percentage amino acid identity as a function of expression level in the Bermuda Atlantic Time Series 20 m sample. Per gene expression level is measured as a ratio - (Transcript abundance in RNA sample)/(Gene abundance in the DNA sample) - with abundance normalized to dataset size. Per gene percentage amino acid identity is averaged over all reads with top BLASTX matches to that gene.
