Gene Details:

• MSU gene ID: LOC_Os06g47150
• RAPdb gene ID: Os06g0685700
• Gene Symbol: OsARF18 RST1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Meanwhile, the transcriptional repressors OsARF18 and OsARF22 were upregulated in the callus of hda710.
• The ChIP-qPCR analysis demonstrated that the callus of hda710 exhibited enhanced histone H3 acetylation levels at the chromatin regions of OsARF18 and OsARF22.
• Additionally, overexpression of OsARF18 decreased the transcription of downstream genes PLT1 and PLT2, and inhibited callus formation of mature embryo.
• Loss of RST1 function increased the expression of OsAS1 and improved nitrogen (N) utilization by promoting asparagine production and avoiding excess ammonium (NH(4)(+)) accumulation.
• Transcriptional repressor RST1 controls salt tolerance and grain yield in rice by regulating gene expression of asparagine synthetase.
• Map-based cloning revealed that the gene RST1 encoded an auxin response factor (OsARF18).
• RST1 was undergoing directional selection during domestication.
