Gene Details:

• MSU gene ID: LOC_Os04g01590
• RAPdb gene ID: Os04g0106300
• Gene Symbol: OsARG
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
