Gene Details:

• MSU gene ID: LOC_Os06g04710
• RAPdb gene ID: Os06g0139000
• Gene Symbol: DDF1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In this study, we characterized a recessive mutant dwarf and deformed flower 1-1 (DDF1-1) in Oryza sativa (rice).
• DDF1 controls organ size by regulating both cell division and cell expansion.
• In the DDF1-1 spikelet, the specification of floral organs in whorls 2 and 3 is altered, with most lodicules and stamens being transformed into glume-like organs and pistil-like organs, respectively, but the specification of lemma/palea and pistil in whorls 1 and 4 is not affected.
• DDF1 encodes an F-box protein anchored in the nucleolus, and is expressed in almost all vegetative and reproductive tissues.
• Collectively, these results revealed that DDF1, as a newly identified F-box gene, is a crucial genetic factor with pleiotropic functions for both vegetative growth and floral organ specification in rice.
• Consistent with the mutant floral phenotype, DDF1 positively regulates B-class genes OsMADS4 and OsMADS16, and negatively regulates pistil specification gene DL.
