  Abstract

Although two homologs of PISTILLATA, OsMADS2 and OsMADS4, have been identified in the rice genome, their roles in floral organ development are controversial. Here, we demonstrate that the two genes show unequal redundancy of class-B function. Although OsMADS2 plays the important role in lodicule development, OsMADS4 also supports specification of lodicule identity. On the other hand, the two genes are almost equally important in stamen development. Consistent with their redundant function, both OsMADS2 and OsMADS4 interact with SPW1, the unique rice AP3 ortholog.

Keywords: OsMADS2 - OsMADS4 - redundancy - SPW1 - lodicule - stamen
