Expression of the Genes Encoding the Trk and Kdp Potassium Transport Systems of Mycobacterium tuberculosis during Growth In Vitro

⁸⁶Rb⁺-uptake efficiencies of the WT and trk-gene knockout strains at the mid- and late-log phases. The results are of three separate experiments with a total of 10–15 replicates for the mid- and late-log phases, respectively. Statistical significance was determined between the two strains within each growth phase and for each strain between the two growth phases. . The absolute radioactive cpm values were and and and for WT and trk-gene knockout strains at mid- and late-log phases, respectively.
