The genes in our eight strains that lacked a syntenic companion in MG had been checked against other E. coli genomes, bacteriophages, and NCBI’s nonredundant (NR) sequence database. Some are as a consequence of insertions for example prophages (Fig. S) or extrachromosomal components like the F plasmid. Other individuals are because of: Prodigal annotation errors, e.g. split gene models; genes annotated as pseudogenes in MG; genes missed by the syntenic gene pairs assignment algorithm.
