The global transcriptome responds specifically to iron deficiency and NaHS treatments. a Venn diagrams showing the DEGs that were up-regulated and down-regulated by NaHS treatment under iron deficiency and iron sufficiency conditions in roots of Glycine max plants. b Specific significantly enriched Kyoto Encyclopedia of Genes and Genomics (KEGG) pathways for DEGs by NaHS treatment under iron deficiency condition (c) Hierarchical clustering of the up-regulated of 309 DEGs (left) and down-regulated of 980 DEGs (right) by NaHS treatment under iron deficiency and iron sufficiency conditions in roots of Glycine max plants. –Fe, 1 μM Fe; −Fe + NaHS, seedlings treated with 100 μM NaHS and 1 μM Fe; +Fe, 50 μM Fe; +Fe + NaHS, seedlings treated with 100 μM NaHS and 50 μM Fe.
