Analysis of the studied loci for the 38 nectar isolates of Pseudomonas characterised in this study.

*Excluding gaps and missing data.†Nucleotide diversity (average number of nucleotide differences per site between two sequences [98]), after Jukes and Cantor correction.‡Ratio between the numbers of non-synonymous and synonymous substitutions (dN and dS, respectively). NA, not applicable.¶Tajima’s D neutrality test [44]. No significant (p>0.05) deviation from zero was observed for any of the studied loci.
