Gene Details:

• MSU gene ID: LOC_Os04g52230
• RAPdb gene ID: Os04g0611800
• Gene Symbol: OsKS1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The OsKS1 mutant seedlings were responsive to exogenous gibberellin (GA3).
• 3 kb were detected in leaves and stem of wild-type plants, but not in germinating seeds or roots, suggesting that OsKS1 is not involved in germination or root growth.
• Expression of OsKS1, one of the genes encoding for GA biosynthetic enzymes, was suppressed in the antisense transgenic lines.
• The expression levels of gibberellin (GA) biosynthetic genes including OsCPS1, OsKS1, OsKO1, OsKAO, OsGA20ox2/SD1 and OsGA2ox3 were significantly increased in d62 mutant.
• As mutations in three recently reported rice GA-responsive dwarf mutant alleles and the dwarf mutation identified in this study mapped to the same locus, we designate the corresponding gene OsKS1.
