• Key message
  • 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
• Connection
  • DDF1, OsMADS16~SPW1, Dwarf and deformed flower 1, encoding an F-box protein, is critical for vegetative and floral development in rice Oryza sativa L., Consistent with the mutant floral phenotype, DDF1 positively regulates B-class genes OsMADS4 and OsMADS16, and negatively regulates pistil specification gene DL
  • DDF1, OsMADS4, Dwarf and deformed flower 1, encoding an F-box protein, is critical for vegetative and floral development in rice Oryza sativa L., Consistent with the mutant floral phenotype, DDF1 positively regulates B-class genes OsMADS4 and OsMADS16, and negatively regulates pistil specification gene DL
  • DDF1, RFL~APO2~SSC, Dwarf and deformed flower 1, encoding an F-box protein, is critical for vegetative and floral development in rice Oryza sativa L., In addition, DDF1 also negatively regulates the Arabidopsis LFY ortholog APO2, implying a functional connection between DDF1 and APO2
