Fig. 1: Chromosome and plasmid phylogeny of manure and manured agricultural grasslands Escherichia coli.

The phylogeny tree of all E. coli is used to describe the levels of relatedness across source, plasmid and chromosome. The outer ring describes the source from which the E. coli were isolated. The same source is denoted by the same colour. The middle ring classifies the plasmids into related groups. The same plasmid group is denoted by the same colour and the same name. The inner ring contains the isolate name and the chromosome group. The phylogenetic tree shows the relatedness of each isolate based on the total genome. The flat lines denotes that the isolates are highly related.
