GC-contents of genomic tetX in different hosts.

Host	GC-content of tetX	Genomic GC-content of TRB	Difference over 10%
Pseudomonas caeni 14	38.3	48.3	Yes
Pedobacter bauzanensis 77	38.5	38.7	No
Psychrobacter pulmonis 135	38.3	42.8	Yes
Lysobacter antibioticus 152	38.3	67.0	Yes
Facklamia tabacinasalis 168	38.5	38.9	No
Wautersiella falsenii EMB5	38.7	32.1	Yes

tetX was amplified using the primer pair tetX-FW (5′-ATGACAATGCGAATAGATACAGACA-3′) and tetX-RV (5′-CAATTGCTGAAACGTAAAGTC-3′).
