Fig. 4From: Conserved phylogenetic distribution and limited antibiotic resistance of class 1 integrons revealed by assessing the bacterial genome and plasmid collectionThe phylogram of type A integrons carrying ARGs normalized against the species level, on a chromosomes and b plasmids. The types of integron elements were differentiated by symbols. The structure of integrons was merged into a phylogenetic tree of their hosts to construct the phylogramBack to article page
