• The sex determination is an event of great relevance in the life cycle of those plants that reproduce sexually. In recent years we have obtained substantial advances in elucidating the mechanisms involved, and in particular the role of epigenetic factors, in plant sex determination. Taking into account the relevance of this topic especially for dioecious species threatened as Cycads studies have been underwent to determine the basis of epigenetics of sex and to test whether compounds such as the de-metilating agent 5-azacytidine may be involved in sexual expression. This paper reviews the main progress made within this context obtained in Z. furfuraceae as well as cases of reversal of sex in cycads and different plant species.
