MIKCC-type MADS box genes encode transcription factors that play crucial
roles in plant growth and development. Analysis of the grapevine (Vitis vinifera) genome revealed up to
38MIKCC-type genes.We report here a complete analysis of this gene family regarding
their phylogenetic relationships with homologous genes identified in other
sequenced dicot genomes, their genome location, and gene structure and
expression. The grapevine genes cluster in 13 subfamilies with their
Arabidopsis (Arabidopsis thaliana) and poplar (Populus trichocarpa) counterparts. The
lack of recent whole genome duplications in grapevine allows assigning the gene
diversification processes observed within each subfamily either to an ancestral
polyploidization event predating the divergence of those three species or to
later duplication events within each lineage. Expression profiles of MIKCC-type genes in
vegetative and reproductive organs as well as during flower and tendril
development show conserved expression domains for specific subfamilies but also
reflect characteristic features of grapevine development. Expression analyses
in latent buds and during flower development reveal common features previously
described in other plant systems as well as possible new roles for members of
some subfamilies during flowering transition. The analysis of MIKCC-type genes in grapevine
helps in understanding the origin of gene diversification within each subfamily
and provides the basis for functional analyses to uncover the role of these
MADS box genes in grapevine development.
