D Volcano plot of the result from quantitative transcriptome profiling in WT and dja6 dja5 mutant. Statistical analysis was performed using Student's t-test. Data on the X-axis represent the Log2-ratio of FC (fold change) between the absolute abundances of transcripts identified from dja6 dja5 against WT. The Y-axis represents the Log10 of FDR (false discovery rate). All DEGs (differentially expressed genes) with FDR < 0.01 and FC > 2 are marked in grey, while all iron-related DEGs with FDR < 0.01 and FC > 2 are marked in red. The iron-related DEGs labeled with red dots within the black boxes are referred to in the text. All data are based on three biological replicates.
