Numbers of genes changed greater than 1.5 fold in comparisons between Hb, Tf and Lf.

†The numbers correspond to genes up-regulated in the presence of the particular iron source in each comparison.
aThese genes had a significance of p<0.05 in the CyberT test.
*This column shows the genes that are only changed in response to the iron source. The genes that are regulated as a result of differential iron uptake are excluded from this column. This is described in more detail in the text.
¥This column shows the number of genes that were changed in one direction in all biological replicates.
