|a Floral organ development is one of the most vital events in flowering plants and is closely related to ornamental properties. The proliferate flower (a new branch or flower occurring in the centre of a flower) in plants is an interesting type, while the specific molecular mechanism remains largely unknown. Osmanthus fragrans 'Tianxiang Taige' has two different flower morphologies: normal flower and proliferate flower. Phenotypic observation suggested that a normal flower was composed of calyx, petal, stamen and pistil (reduced to leaf-like carpel). While in proliferate flower, the leaf-like carpel continued to grow and was replaced by a new branch. Paraffin section indicated that the re-growth of leaf carpels might be the main reason for proliferate flower formation. Transcriptome sequencing of normal and proliferate flower was performed, and the expression levels of related genes were analysed. Among the differentially expressed genes, OfBFT-a and OfBFT-b had differential expression during the proliferate flower formation process. The expression patterns revealed that both OfBFT-a and OfBFT-b were highly accumulated in carpels, and were significantly downregulated during the proliferate flower development process. Subcellular localization indicated that OfBFT-a and OfBFT-b proteins were located in the nucleus. Functional studies in 'Tianxiang Taige' and Arabidopsis showed that OfBFT-a and OfBFT-b had important roles in floral organ development, especially the proliferate flower formation process by downregulating the accumulation of AG and SEP3 homologous genes. These results may shed new light on the study of proliferate flower formation and flower morphology breeding in flowering plants
