- Publication
- Identification of a novel mitochondrial protein, short postembryonic roots 1 SPR1, involved in root development and iron homeostasis in Oryza sativa, 2011, New Phytol.
- OsARF12, a transcription activator on auxin response gene, regulates root elongation and affects iron accumulation in rice Oryza sativa, 2012, New Phytol.
- Is Reactive Oxygen Species ROS the underlying factor for inhibited root growth in Osspr1?, 2011, Plant Signal Behav.

Genbank accession number
- Key message
- 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
