    Tomato (Solanum lycopsersicum) which forms a small monophyletic clade within the large Solanaceae family has been chosen as a model system for studying the Solanaceae genome, fruit development and ripening. At that time, many efforts have been devoted to the analysis of the genetic diversity of tomato species, little work has focused on the analysis epigenetic diversity in this clade, although there is a general agreement that epigenetic processes play essential role in the phenotypic diversity in animal and plant system. As first step, DNA methylation level was analyzed in leaves and fruits of various wild and cultivated tomato species.Additionally, the Enhancer of zest (E(z)) gene family has been analyzed. In tomato, the E(z) family consists in two functional genes (SlEZ1, SlEZ2) and in a pseudogene (SlEZ3). In addition, the epigenetic stability is an important consideration that could have a significant on strategies for crop breading. Finally, we made a fine characterization of the different aspects of fruit development and ripening.
