log fraction of singletons log genome size log fraction of singletons temperature, C Supplementary Figure 1. A predictive model for the fraction of singletons (A), transferred genes inferred by dinucleotide composition (B) and prophage genes (C) in genomes of archaea and bacteria. Surfaces (top: archaea, bottom: bacteria) indicate the expected fraction of singletons given the optimum growth temperature and genome size.
