The involvement of MADS-box transcriptionfactors in the development of seeds, flowers, and fruit iswell known. Large numbers of MADS-box genes havebeen characterized and reported in major plants such asArabidopsis thaliana (107), Oryza sativa (75), Zea mays(75), and Cucumis sativus (43). However, there is littleinformation about MADS-box genes in the economicallyand morphologically important genus Brassica. Thus, weperformed a series of computational analyses on therecently published Brassica rapa genome and identified167 potential MADS-box genes. Chromosomal localizationof these genes revealed many duplicate genes and 10 tandemrepeats from B. rapa chromosomes, though none onA04, A08, and A10. Neighbor-joining phylogenetic analysiswas performed between B. rapa, A. thaliana, O. sativa,Z. mays, and C. sativus genes, and type-I and type-IIgroups were differentiated by their gene clades. Based ontheir phylogeny and functional characters, type-I group wasdivided into three clades and type-II group into 14 clades.
Prediction and comparison of intron and exon patterns ofMADS-box genes authenticates the major differencebetween the groups. Semi-quantitative RT-PCR analysiswas carried out for 25 functionally categorized BrMADSboxgenes and comparatively studied among buds, sepals,petals, stamens, carpels, and siliques of the parental lineRcBr. The structural and functional annotation, as well asexpressional profiling of BrMADS in floral organs in thisstudy will be the basis of further functional validation andmolecular breeding of B. rapa crops.
