Background  The classical ( C ) MIKC-type MADS-box transcription factors comprise one gene family that plays diverse roles in the flowering process ranging from floral initiation to the development of floral organs. Despite their importance in regulating developmental processes that impact crop yield, they remain largely unexplored in the major legume oilseed crop, soybean.    Results  We identified 57 MIKC c -type transcription factors from soybean and determined the  in silico  gene expression profiles of the soybean MIKC c -type genes across different tissues. Our study implicates three MIKC c -type transcription factors as novel members of the  AGAMOUS LIKE 6  (AGL6) subfamily of the MIKC C -type MADS-box genes, and we named this sister clade PsMADS3. While similar genes were identified in other legume species, poplar and grape, no such gene is represented in  Arabidopsis thaliana  or rice. RT-PCR analysis on these three soybean PsMADS3 genes during early floral initiation processes revealed their temporal expression similar to that of  APETALA1 , a gene known to function as a floral meristem identity gene. However, RNA  in situ  hybridisation showed that their spatial expression patterns are markedly different from those of  APETALA1.Conclusion  Legume flower development system differs from that in the model plant, Arabidopsis. There is an overlap in the initiation of different floral whorls in soybean, and inflorescent meristems can revert to leaf production depending on the environmental conditions. MIKC C -type MADS-box genes have been shown to play key regulatory roles in different stages of flower development. We identified members of the PsMADS3 sub-clade in legumes that show differential spatial expression during floral initiation, indicating their potential novel roles in the floral initiation process. The results from this study will contribute to a better understanding of legume-specific floral developmental processes.
