在水稻中已鉴定出两个与雌蕊蛋白同源的基因：OsMADS2和OsMADS4。然而，它们在花器官发育中的作用存在争议。在这里，我们证明了基因显示不相等的B类功能冗余。尽管OsMADS2在lodile开发中起着重要作用，但OsMADS4也支持lodile标识规范。相比之下，这些基因在雄蕊发育过程中的作用大致相同。与OsMADS2和OsMADS4的冗余功能一致，它们都与水稻AP3的独特同源物SPW1相互作用。
Two homologs of PISTILLATA have been identified in rice: OsMADS2 and OsMADS4. However, their roles in floral organ development are controversial. Here, we demonstrate that the genes show unequal redundancy of class B function. Although OsMADS2 plays an important role in lodicule development, OsMADS4 also supports the specification of lodicule identity. In contrast, the genes are roughly equally important in stamen development. Consistent with their redundant functions, both OsMADS2 and OsMADS4 interact with the unique rice AP3 ortholog SPW1.
