• Information
  • Symbol: OsSPDS2,OsSPMS1
  • MSU: LOC_Os06g33710
  • RAPdb: Os06g0528600
• Publication
  • A distinctive class of spermidine synthase is involved in chilling response in rice, 2004, Journal of Plant Physiology.
  • The Spermine Synthase OsSPMS1 Regulates Seed Germination, Grain Size, and Yield., 2018, Plant Physiol.
• Genbank accession number
  • AB098063
• Key message
  • OsSPDS2 mRNA accumulated in roots during long term exposure to chilling temperature (12 degrees C)
  • Data suggested a distinct function of OsSPDS2 in chilling response in rice
  • ABA treatment up-regulated OsSPDS2, whereas salt stress did not change OsSPDS2 levels significantly
  • These data suggest that OsSPMS1 affects ethylene synthesis and may regulate seed germination and plant growth by affecting the ACC and ethylene pathways
  • The Spermine Synthase OsSPMS1 Regulates Seed Germination, Grain Size, and Yield.
  • Phenotypic analysis indicated that OsSPMS1 negatively regulates seed germination, grain size, and grain yield per plant
  • Most importantly, an OsSPMS1 knockout mutant showed an increase in grain yield per plant in a high-yield variety, Suken118, suggesting that OsSPMS1 is an important target for yield enhancement in rice
