Gene Details:

• MSU gene ID: LOC_Os05g34940
• RAPdb gene ID: Os05g0423400
• Gene Symbol: OsMADS4
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• The global architecture of transcripts regulated by OsMADS2 gives insights into the regulation of cell division and vascular differentiation that together can form this highly modified grass organ with important functions in floret opening and stamen emergence independent of the paralogous gene OsMADS4.
• Our results demonstrate that OsMADS16 is an AP3/DEF orthologue to specify the identities of lodicules and stamens in rice flower and also support that OsMADS4 is a PI orthologue.
• Transcription of a rice PI homologous gene, OsMADS4, was also reduced remarkably in the transgenic plants.
• Consistent with the mutant floral phenotype, DDF1 positively regulates B-class genes OsMADS4 and OsMADS16, and negatively regulates pistil specification gene DL.
• Unequal genetic redundancy of rice PISTILLATA orthologs, OsMADS2 and OsMADS4, in lodicule and stamen development.
• Our data demonstrate its essential role in lodicule development and implicate the second PI/GLO paralog, OsMADS4, to suffice for stamen specification.
