Table 1 Results of the linear mixed-effects model testing the additive effects of genome size and synonymous core genome diversity (πsyn, ln-transformed) on accessory genome fluidity (ϕ, ln-transformed) with random intercepts fitted for each broad phylogenetic group (that is, Proteobacteria and Terrabacteria)

From: Prokaryote genome fluidity is dependent on effective population size

  1. Abbreviation: NS, not significant.
  2. aNote: significance of parameter estimates are based on Wald’s t-test, ***P<0.001.
  3. The most parsimonious model was arrived at by sequentially deleting terms and comparing model fits using F-tests of likelihood ratios.
