There were 1160 Clade 1 specific genes (Supplementary Table 3a), 3078 Clade 2 specific genes (Supplementary Table 3b), 2452 Clade 3 specific genes (Supplementary Table 3c), and 507 Clade 4 specific genes (Supplementary Table 3d). The tetracycline destructase gene was found in two Clade 2 species (L. jordanis and L. nautarum) and in Clade 3 species L. longbeachae but not in the other two clades.
