Class 1 integron gene cassette inserts. Relative frequency of insert types for each Site (A). Absolute counts of annotated gene cassette inserts for each Site (B). Resistance against streptomycin (pink), beta-lactamase (red), chloramphenicol (orange), trimethoprim (yellow), erythromycin (green) and quaternary ammonium compounds (turquoise). “No known function” (dark grey) refers to reads without known annotation in GenBank database. “No insert” (light grey) refers to reads where 5’CS and 3’CS were directly linked, without a variable region in between.
