Gene Details:

• MSU gene ID: LOC_Os01g67290
• RAPdb gene ID: Os01g0898300
• Gene Symbol: Osspr1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In this addendum, we proposed a possible hypothesis that Osspr1 maintained the mitochondria function to restrict H2O2 production in root apex for normal root development.
• Is Reactive Oxygen Species (ROS) the underlying factor for inhibited root growth in Osspr1?.
• The knockout of OsARF12 also altered the abundance of mitochondrial iron-regulated (OsMIR), iron (Fe)-regulated transporter1 (OsIRT1) and short postembryonic root1 (Osspr1) in roots of rice, and resulted in lower Fe content.
• • A rice mutant, Oryza sativa short postembryonic roots 1 (Osspr1), has been characterized.
• • Osspr1 mutants exhibited decreased root cell elongation.
• Complementation of the mutant confirmed that Osspr1 is involved in post-embryonic root elongation and iron homeostasis in rice.
