Fold changes of ≥2 in transcript levels were considered.
HI and LI represent high (8 μg Fe ml−1)- and low (0.02 μg Fe ml−1)-iron conditions of growth.
The P values were calculated based on multiple probes used for each gene using the t test method.
Gene products are indicated as described by Mycobacterial Browser (Mycobrowser; Tuberculist version 2.6; http://tuberculist.epfl.ch/), except that the terms “probable” and “possible” are removed. CHP, conserved hypothetical protein; CMP, conserved membrane protein; CTMP, conserved transmembrane protein.
