Fig. 5: Gene expression profiles for syntrophic petroleum alkane oxidation.
a,b, Fragment counts normalized to gene length (FPK) shown on a logarithmic y axis. The average gene expression of each organism is indicated as arithmetic mean (sum of all FPK values divided by number of genes) depicted as a horizontal line. c,d, Fragment counts normalized as CLR. For simplicity, only the values of the more active Ca. Alkanophaga species are shown. For abbreviations, see Fig. 4; hyd, gene encoding [NiFe]-hydrogenase; fdh, gene encoding formate dehydrogenase; cyt, gene encoding multihaem cytochrome.
