Figure A1.
Hfq expression is not affected by the presence of Zn. Transcription of hsp70, hfq and czcR genes in the WT and the ΔczcRS mutants grown in LB medium in the absence or presence of 0.5 mM Zn as indicated, analyzed by semi-quantitative RT-PCR. Negative controls (hsp70 gene) lacked reverse transcriptase (RT-).
