• Information
  • Symbol: SAUR39
  • MSU: LOC_Os09g37330
  • RAPdb: Os09g0545300
• Publication
  • SAUR39, a small auxin-up RNA gene, acts as a negative regulator of auxin synthesis and transport in rice, 2009, Plant Physiol.
• Genbank accession number
  • AK241264
• Key message
  • The expression of the rice (Oryza sativa) SAUR39 gene showed rapid induction by transient change in different environmental factors, including auxin, nitrogen, salinity, cytokinin, and anoxia
  • Transgenic rice plants overexpressing the SAUR39 gene resulted in lower shoot and root growth, altered shoot morphology, smaller vascular tissue, and lower yield compared with wild-type plants
  • The SAUR39 gene was expressed at higher levels in older leaves, unlike auxin biosynthesis, which occurs largely in the meristematic region
  • Taken together, the results suggest that SAUR39 acts as a negative regulator for auxin synthesis and transport
  • SAUR39, a small auxin-up RNA gene, acts as a negative regulator of auxin synthesis and transport in rice
• Connection
  • SAUR39, TIG1, Natural Variations at TIG1 Encoding a TCP Transcription Factor Contribute to Plant Architecture Domestication in Rice., The TIG1 protein activates the expression of EXPA3, EXPB5 and SAUR39 to regulate cell elongation and increase the tiller angle
