✦ Synopsis

Histone acetyltransferases (HATs) and deacetylases (HDACs) play critical roles in the regulation of chromatin structure and gene expression. In plants, these genes are emerging as crucial players in all aspects of development. As part of our study regarding the growth and development of grapevine (Vitis vinifera), we report the genome-wide analysis of HAT and HDAC genes. This analysis revealed the presence of 7 and 13 genes coding for putative HATs and HDACs, respectively. In this work, we present a complete analysis of these families with regards to their phylogenetic relationships with orthologous genes identified in other sequenced plant genomes, their genome location, gene structure and expression. The genes identified can be grouped into different families as has been previously described for other eukaryotic species. The organ-specific expression pattern of HAT and HDAC genes indicates that some genes have different expression profiles, and their potential involvement during grape development is discussed.
