HvOS1 and HvOS2 are members of a grass-specific class of MADS box genes. A, Diagrammatic representation of the syntentic region in rice and B. distachyon that contains the ODDSOC-like genes (OsMADS51, BdOS1, and BdOS2), and the corresponding barley Unigene numbers and map locations. Arrows indicate the direction of transcription. B, Phylogenetic relationships between the ODDSOC-like genes of rice (OsMADS51), maize (ZmOS-like), sorghum (SbOS-like), barley (HvOS1 and HvOS2), wheat (TaAGL33, TaAGL41, and TaAGL42), and B. distachyon (BdOS1-like and BdOS2-like) based on a sequence alignment of the coding sequence for each gene.
