Genes significantly differentially expressed in response to iron stress. Significantly differentially expressed genes (DEGs) (FDR < 0.05) were identified by comparing gene expression in iron deficient conditions to iron sufficient conditions (D/S). Porcupine plots were used to visualize the expression of all genes and all DEGs. Expression of all genes is shown in grey. Expression of DEGs is shown in red (repressed by iron deficiency) and blue (induced by iron deficiency). A line joins replicates of DEGs. A. DEGs from leaves after one hour of iron stress. B. DEGs from leaves after six hours of iron stress. C. DEGs from roots after one hour of iron stress. D. DEGs from roots after six hours of iron stress. E. Bar graph of the total number of repressed or induced differentially expressed genes at each tissue and time point.
