MADS-box transcription factor (TF), primarily involved in the floral organ specification with other several aspects of plant growth and development. Whole genome survey of B. rapa revealed 167 MADS-box genes and categorized into MIKCc, MIKC*, Mα, Mβ and Mγ groups based on phylogeny, protein motif structure and exon-intron organizations. MIKCc group belongs 89 genes, which is the highest in number than in any other crops till date. The MIKCc group has further classified into 13 sub-families. In case of chromosomal localization, remarkably 57 MIKCc type MADS-box genes were found in the duplicated segments of B. rapa genome, whereas only 4 M-type genes have resulted from tandem duplications. Besides floral and vegetative tissue expression we also identified MADS-box genes with their male and female gametophyte specific expression in different stages of flower bud development. Furthermore, from a low temperature treated whole genome microarray data set 19 BrMADS genes were found to show variable transcript abundance in two contrasting double haploid lines of B. rapa. Subsequently, the responsive genes were investigated under three abiotic stresses where they showed differential and corresponsive expression patterns. An extensive annotation and transcriptome profiling undertaken in this study might be useful for understanding the involvement of MADS-box genes in stress resistance besides their growth and developmental functions, which ultimately will provide the basis for functional characterization and exploitation of the candidate genes in the genetic engineering study of B. rapa
