Figure 1.

Extensive variation in plasmid donor and recipient ability across field isolates of Escherichia coli. Conjugation rates were measured in liquid with shaking over 3 h, towards K-12 MG1655 RifR (donor ability) and from K-12 MFDpir (recipient ability). Individual replicates are shown as dots, lines are geometric means. Rates with K-12 as both donor and recipient are shown on the left; field isolates are then ordered by their phylogenetic distance to K-12. Colour indicates site of origin for each isolate. A tree showing phylogenetic relationships is shown under strain names.
