FIG 1.

Mean Ultra T_m value ± 1 SD determined for 41 rpoB genotypes. Mutations from 511CCG through 512ACC_515ATT_526AAC showed unique mutant T_m window patterns. Mutations from 516TAC through 513CTA_523GAG had undistinguishable mutant T_m window patterns, but they showed different WT T_m window patterns. Colored labels represent 3 mutant groups, each containing 2 mutations that have similar T_m patterns. The single asterisk (*) indicates that 513CAG is a silent mutation (Q513Q) and all 4 T_m values fall within WT windows. The double asterisks (**) indicate that the rpo2 T_m value of 518GAC_533CCG could fall within the WT window or the Mut window or neither.
