Gene Details:

• MSU gene ID: LOC_Os03g54000
• RAPdb gene ID: Os03g0751100
• Gene Symbol: OPT OsOPT7
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Histochemical activity of beta-glucuronidase in transgenic rice plants containing the promoter of OsTZF1 fused with beta-glucuronidase was observed in callus, coleOPTile, young leaf, and panicle tissues.
• Promoter GUS analysis revealed that OsOPT7 expresses in root tips, root vascular tissue and shoots as well as during seed development.
• Furthermore OsOPT7 did not complement the growth of yeast fet3fet4 mutant.
• Microarray analysis of OsOPT7 knockout 1 (opt7-1) revealed the upregulation of Fe-deficiency-responsive genes in plants grown under Fe-sufficient conditions, despite the high Fe and ferritin concentrations in shoot tissue indicating that Fe may not be available for physiological functions.
• Iron deficiency regulated OsOPT7 is essential for iron homeostasis in rice.
• OsOPT7 localized to the plasma membrane and did not transport Fe(III)-DMA or Fe(II)-NA and GSH in Xenopus laevis oocytes.
