Abstract
This proposal is focused on the research projects which have been currently developed by the proponent Milton Groppo, their colaborators and their students at Laboratory of Plant Systematics, FFCLRP-USP. The main idea is the understanding of systematics and evolution in an integrative way, which involves alpha taxonomy (such as taxonomic revisions and flora surveys), phylogenetic and biogeographic studies, and ontogeny of leaves. Projects are concentrated in three taxa (families) - Rutaceae, Asteraceae and Rubiaceae. Proposed activities are formatted according to these three main areas, each corresponding to the botanical family with the highest concentration of studies. In the first main area - RUTACEAE - phylogenetic studies based on molecular data focused on Neotropical tribe Galipeeae will be performed, with two sub-tribes Galipeinae and Pilocarpinae, a group of 27 genera and about 150 species. Other taxa that are traditionally placed in other groups of Rutaceae, but nowadays known to be phylogenetically near Galipeeae, as Balfourodendron, Helietta and Hortia, will also be included. The more accurate phylogenetic hypotheses will be used as a basis of studies of the leaf anatomy of groups Galipeinae and Hortia. Finally, in this first main area (Rutaceae) floristic survey focused in Rutaceae will be performed, as the monographs for the flora of the states of Sergipe, Espírito Santo and Bahia. They are also provided for the preparation of the treatment for the Flora of Brazil, in addition to the treatment of Rutaceae for Mesoamerican Flora. A review for the species of Almeidea A.St.Hil., now reduced to synonymy of Conchocarpus J.C.Mikan will also be held. In the second main area - ASTERACEAE - the studies will be focused on the subfamily Barnadesioideaethe sister group of all other Asteraceae. This study aims to investigate the monophyly of the genera in Barnadesioideae and infrageneric relationships in Dasyphyllum, Chuquiraga and barnadesia with the use of molecular data. Phylogenetic hypotheses will be associated with studies of historical biogeography and ancestral areas, diversification and divergence times. The third main area is focused on RUBIACEAE family, with a taxonomic revision of Simira Aubl., a genus with 40-50 species from Central America to northern Argentina. Another genues of the same family, Rudgea Salisb., with ca. 100 species, will be studied, with a synopsis of the genus in Brazil and also a phylogenetic and biogeographic analysis for the group as a whole. Other side projects on flora and floristic surveys will be performed, with samples collected, maximizing the use of resources. In all projects in field samples will be collected for DNA extraction for possible future phylogenetic studies, and possibility new species to science could be described. (AU)
