dc.description.abstractOsMADS6, an ancient AGAMOUS-LIKE6 (AGL6)-like gene, has essential functions in specifying floral organ and meristem identity in rice (Oryza sativa). However, how AGL6 genes control flower development remains largely unknown. In this study, we report that OsMADS6 directly targets FACTOR OF DNA METHYLATION LIKE 1 (OsFDML1), a rice homolog of the SUPPRESSOR OF GENE SILENCING3-like gene FACTOR OF DNA METHYLATION 1 (FDM1) from Arabidopsis (Arabidopsis thaliana). Arabidopsis FDM1 is involved in RNA-directed DNA methylation and OsFDML1 regulates flower development. The expression of OsFDML1 overlaps with that of OsMADS6 in the palea primordia and the ovule, and OsMADS6 directly promotes OsFDML1 expression through binding to regions containing putative CArG motifs within the OsFDML1 promoter during rice spikelet development. Consistent with the phenotypes of osmads6 mutants, the osfdml1 mutants showed floral defects, including altered palea identity with lemma-like shape containing no marginal region of palea, increased numbers of stigmas and fused carpels, and meristem indeterminacy. Moreover, transgenic plants overexpressing OsFDML1 displayed floral defects, such as abnormal paleae. Phylogenetic analysis showed that OsFDML1 homologs exist only in terrestrial plants. In addition, protein-protein interaction assays showed that OsFDML1 interacts with its close paralog OsFDML2, similar to the activity of OsFDML1 homologs in Arabidopsis. These results provide insight into how the ancient AGL6 gene regulates floral development.en
