Transcriptional Response of Selenopolypeptide Genes and Selenocysteine Biosynthesis Machinery Genes in Escherichia coli during Selenite Reduction

Figure 2

Effect of low concentrations of Na2SeO3 treatment on E. coli cell growth and selenite reduction. (a) The effect of 0 to 10 mM Na2SeO3 on cell growth rates. The experiment was performed with three biological replicates and each Na2SeO3 treated sample was analyzed in triplicate. Data plotted was the average of growth ± SD. The concentrations (0, 0.01, and 5 mM) that were marked in blue were used to prepare RNA samples for microarray analysis. (b) Color change in cultures after treatments with 0 to 10 mM Na2SeO3. .
