Transcriptional changes in roots of genes involved in the Methionine cycle/DMA synthesis and Fe acquisition by Fe deficiency. Abbreviations: YS1 = yellow stripe 1; YS3 = yellow stripe 3 (ZmTOM1 gene, GRMZM2G063306); ST1 = Sulfate transporter 1; SO4 2− = sulfate; Cys = cysteine; hCys = homo-cysteine; FDH = formate dehydrogenase; DEP = methylthioribulose-1-phosphate dehydratase-enolase-phosphatase; IDI1 = 2-keto-methylthiobutyric-acid forming enzyme; IDI4 = putative aminotransferase catalyzing the synthesis of methionine from 2-keto-methylthiobutyric acid; SAMS = S-adenosyl-methionine synthase; MTN = methylthioadenosine/S-adenosyl homocysteine nucleosidase; MTK = methylthioribose kinase; IDI2 = eukaryotic initiation factor 2B-like methylthioribose-1-phosphate isomerase; NAS = nicotinamine synthase; NAAT = nicotianamine amino-transferase; DMAS = 2’-deoxymugineicacid synthase; APT = Adenosin phosphoribosyltransferase; VIT1 = vacuolar iron transporter 1; NRAMP = natural resistance associated macrophage protein; Regulation = GRMZM2G057413 (homology to OsIRO2), GRMZM2G350312 (homology to OsIRO3), GRMZM2G107672 (homology to AtbHLH29), GRMZM2G133675 (homology to AtPYE). Color scale refers to the fold change values of differentially expressed transcripts: red color refers to those transcripts positively regulated by Fe deficiency, while in blue are transcripts negatively regulated Fe deficiency.
