  • a All categories except pseudogenes are single or combined FC headings (reference 31, as classified in reference 28).

  • b Includes the headings amino acid biosynthesis; biosynthesis of cofactors, carriers; central intermediary metabolism; degradation of small molecules; energy metabolism, carbon; fatty acid biosynthesis; and nucleotide biosynthesis.

  • c Includes the headings macromolecule degradation; macromolecule synthesis, modification; and ribosome constituents.

  • d P < 0.05, binomial distribution with Bonferroni correction.
