  1. Log (2) Fold- change values correspond to the average normalized count ratio between LI (low iron) media and HI (high iron) media for each individual strain. *p-values were adjusted using the Benjamin and Hochberg false discovery rate (FDR) approach. Genes with p-values < 0.05 and a base-2 log-ratio ≥ 0.5849 (i.e., ≥ 1.5-fold) or ≤ −0.5848 (i.e., ≤ 0.66-fold) in relation to the HI media were considered as differentially expressed. Gene regulation is based on the LI:HI ratio expression value: UP, up-regulated (log (2) fold-change ≥0.5849); UNC. unchanged (− 0.5849 < log (2) fold-change < 0.5849); DOWN, down-regulated (log (2) fold-change ≤ − 0.5849)
