Natural diversity of Passiflora edulis flowers. We have a collection of different Passiflora edulis genotypes collected from the wild and cultivated under the same environmental conditions. These genotypes show variation in flower size and shape (e.g. deflected or reflected perianth) and in the pigmentation and length of corona

The main interest of our group is to understand how evolution shaped plant diversity tinkering with developmental pathways. We are very found of passionflowers because this particular group of plants presents a wide range of floral innovations that are thought to have arisen through interactions among these plants and pollinators. Nevertheless we sometimes also use Arabidopsis as a model, to understand more fundamental aspects of cell division, differentiation, and the role of these two phenomena in plant morphogenesis. We use a multidisciplinary approach and apply different types of microscopy, molecular and genetic techniques to gain insights about how evolutionary novelties arise in plant reproductive development. Our group is part of the Plant Biology Department, of the Institute of Biology, at the State University of Campinas, which is considered one of the three best Universities in Latin America and one of the World´s best 50 Universities under 50 years old, according to Times Higher Education.
