Ovules have an important role during the life cycle of the plant, and they provide an excellent model for studying organogenesis in plants. As such, the molecular control of ovule development has been studied for many years. Recent studies in Arabidopsis have revealed important new data concerning ovule primordia formation, ovule identity determination, and patterning. Furthermore, interesting results about ovule development in other species, such as Petunia and rice, have been published recently. In this review, we discuss these recent findings in reference to ovule development in Arabidopsis. We compare available data with those of other species to investigate the evolutionary conservation of the regulatory pathways.
