Background MADS-box genes encode transcription factors that are involved in developmental control and signal transduction in eukaryotes. In plants, they are associated to numerous development processes most notably those related to reproductive development: flowering induction, specification of inflorescence and flower meristems, establishment of flower organ identity, as well as regulation of fruit, seed and embryo development. Genomic analyses of MADS-box genes in different plant species are providing new relevant information on the function and evolution of this transcriptional factor family. We have performed a true genome-wide analysis of the complete set of MADS-box genes in grapevine (Vitis vinifera), analyzed their expression pattern and establish their phylogenetic relationships (including MIKC* and type I MADS-box) with genes from 16 other plant species. This study was integrated to previous works on the family in grapevine.
