Comparison between assimilation phenotypes and the numbers of metabolic enzymes in the genome for which a correlation is observed. The phenotypes are from Kurtzman et al. eds. (2011), Satoh and Makimura (2008), and Huang et al. (2011), and are indicated as positive (+), negative (-), variable (v), slow (s), latent (l), weak (w), and not available (n), in line with Kurtzman et al. (2011). The phylogenetic tree on the left is the consensus topology of Figs 1–3. Superscripts after strain numbers indicate ‘type strain’ (T), or ‘reference strain’ (*).
