Gene Details:

• MSU gene ID: LOC_Os06g33710
• RAPdb gene ID: Os06g0528600
• Gene Symbol: OsSPDS2 OsSPMS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• 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.
