1. Enriched gene functions responding to irradiance and pO2.
Enriched gene functions responding to irradiance and pO2. Ratios on the x axis depict the percentage of genes of a particular function (shown on the y axis) in a given category (e.g., RNA polymerase genes increasing their expression with irradiance under binary conditions, top black bar of the upper left figure) divided by the percentage of genes of the same function in the genome as a whole. For comparison, the ratios of functional enrichment are shown for both axenic (white) and binary (black) cultivation with at least one of the two being significantly enriched with a P value of <0.05 as determined by Fisher’s exact test (indicated by *). (A) Functional groups that increased with increasing irradiance. (B) Functional groups that decreased with increasing irradiance. (C) Functional groups that increased with increasing O2 tension (pO2); SUF, sulphur assimilation. (D) Functional groups that decreased with increasing O2 tension. FMN, flavin mononucleotide; FAD, flavin adenine dinucleotide.
