• Information
  • Symbol: OsARG
  • MSU: LOC_Os04g01590
  • RAPdb: Os04g0106300
• Publication
  • OsARG encodes an arginase that plays critical roles in panicle development and grain production in rice, 2012, The Plant Journal.
  • Expression of the Rice Arginase Gene OsARG in Cotton Influences the Morphology and Nitrogen Transition of Seedlings., 2015, PLoS One.
  • Loss of Function of OsARG Resulted in Pepper-Shaped Husk in Indica Rice, 2021, Life (Basel).
• Genbank accession number
  • AK101488
• Key message
  • The OsARG protein was localized in the mitochondria, consistent with other arginases
  • OsARG encodes an arginase that plays critical roles in panicle development and grain production in rice
  • The phenotype was partially corrected supplying exogenous nitrogen, and fully corrected by a wild type OsARG transgene
  • Our results suggest that the arginase encoded by OsARG, a key enzyme in Arg catabolism, plays a critical role during panicle development, especially under conditions of insufficient exogenous nitrogen
  • OsARG, ubiquitously expressed in various organs, was more strongly expressed in the developing panicles
  • The nitric oxide content and the morphology of ARG-26 and ARG-38 seedlings were both affected by expression of the OsARG gene
  • Expression of the Rice Arginase Gene OsARG in Cotton Influences the Morphology and Nitrogen Transition of Seedlings.
  • The unique rice arginase gene OsARG is known to affect nitrogen use efficiency and is also associated with higher yields in rice
