Gene Details:

• MSU gene ID: LOC_Os09g32948
• RAPdb gene ID: Os09g0507200
• Gene Symbol: OsMADS8 OsMADS24
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Plants affected in both OsMADS7 and OsMADS8 show severe phenotypes including late flowering, homeotic changes of lodicules, stamens and carpels into palea/lemma-like organs, and a loss of floral determinacy.
• Simultaneous knockdown of the four rice SEP-like genes OsMADS1, OsMADS5, OsMADS7 and OsMADS8, leads to homeotic transformation of all floral organs except the lemma into leaf-like organs.
• Our results suggest that OsMADS8 is critical for floral organ determination and seed germination and that these effects are the result of regulation of the expression of OsEMF2b and its role in ABA signaling and catabolism.
• Overexpression of OsMADS8 led to decreased expression of OsEMF2b and ABA signaling-related genes including OsVP1/ABI3.
