“…Four clades are recovered within Urticaceae, congruent with Wu et al (), which correspond to Urticeae, Elatostemateae, the Boehmerieae–Forsskaoleeae–Parietarieae clade, and the “Cecropieae” clade (see Hadiah et al, ; Kim et al, ). Cecropieae are embedded in Urticaceae, and they are polyphyletic, with Poikilospermum nested in Urticeae (BS = 70%; also see Hadiah et al, ; Wu et al ; Kim et al, ). Within Urticeae, Didymodoxa + ( Obetia + Urera – Poikilospermum ) are sister to an unresolved group including Laportea , Dendrocnide , Boehmeria , Urtica , Hesperocnide , and Girardinia (BS = 97%).…”

Rosidae, a clade of approximately 90 000 species of angiosperms, exhibits remarkable morphological diversity and extraordinary heterogeneity in habitats and life forms. Resolving phylogenetic relationships within Rosidae has been difficult, in large part due to nested radiations and the enormous size of the clade. Current estimates of phylogeny contain areas of poor resolution and/or support, and there have been few attempts to synthesize the available data into a comprehensive view of Rosidae phylogeny. We aim to improve understanding of the phylogeny of Rosidae with a dense sampling scheme using both newly generated sequences and data from GenBank of the chloroplast rbcL, atpB, and matK genes and the mitochondrial matR gene. We combined sequences from 9300 species, representing 2775 genera, 138 families, and 17 orders into a supermatrix. Although 59.26% of the cells in the supermatrix have no data, our results generally agree with previous estimates of Rosidae phylogeny and provide greater resolution and support in several areas of the topology. Several noteworthy phylogenetic relationships are recovered, including some novel relationships. Two families (Euphorbiaceae and Salvadoraceae) and 467 genera are recovered as non-monophyletic in our sampling, suggesting the need for future systematic studies of these groups. Our study shows the value of a botanically informed bioinformatics approach and dense taxonomic sampling for resolving rosid relationships. The resulting tree provides a starting point for large-scale analyses of the evolutionary patterns within Rosidae.Key words: phylogeny, rapid radiation, Rosidae, supermatrix.With approximately 90 000 species (estimated from Hinchliff et al., 2015), 135-140 families, and 17 orders (Soltis et al., 2005;APG III, 2009;APG IV, 2016), Rosidae contains at least one quarter of all angiosperm species and approximately 39% of eudicot species diversity (Magall on et al., 1999;Wang et al., 2009). Molecular dating indicates that Rosidae originated in the Early to Late Cretaceous, between 115 and 93 million years ago (Mya), followed by rapid diversification resulting in the Fabidae and Malvidae crown groups approximately 112 to 91 Mya (Albian to Coniacian) and 109 to 83 Mya (Cenomanian to Santonian), respectively (Wang et al., 2009;Bell et al., 2010), with major lineages diversifying in perhaps as little as 4 to 5 million years (Wang et al., 2009;Soltis et al., 2010). The radiations in Rosidae also represent the rapid rise of angiosperm-dominated forests and associated co-diversification events that have profoundly shaped much of the current terrestrial biodiversity (Wang et al., 2009).This extraordinarily diverse clade exhibits enormous heterogeneity in habitats and life forms, including herbs, shrubs, trees, vines, aquatics, succulents, and parasites. Species of Rosidae generally have bitegmic, crassinucellate ovules, distinguishing them from Asteridae, which are generally characterized by unitegmic, tenuinucellate ovules. Moreover, some members possess novel bio...

AgradecimentosA Deus, por conceder-me a vida, a oportunidade de crescimento e pelas pessoas colocadas em meu caminho para me ajudarem durante esta trajetória.À minha orientadora Dra. Simone de Pádua Teixeira, pela orientação impecável, pelos ensinamentos, pela amizade e atenção a mim dedicadas e por ter acreditado e confiado em meu trabalho, um exemplo a ser seguido. Pessoa pelo qual tenho imenso carinho e admiração. Aos membros da banca examinadora, pela disponibilidade, tempo e dedicação conferidos a avaliação deste trabalho.Aos Professores e funcionários do Departamento de Biologia, Programa de Biologia Comparada, pela contribuição à minha formação científica. Most species of Urticaceae, the nettle family, exhibit very small and inconspicuous diclinous flowers, which vary in number of organs, mainly in relation to the perianth and androecium (loss or union of organs). Pseudomonomerous gynoecium, that is, initiation of two or rarely three carpels in the floral meristem, but with only one carpel containing ovule, is (Urticaceae); The pistillodium, together with the sepals and stamens, forms an apparatus that acts on the mechanism of explosive release of pollen to be carried by the wind. This apparatus is here considered as a floral synorganization, without a true union between tissues, that should optimize the anemophily, so that the pollen can reache greater distances, avoiding selfpollination and guaranteeing greater genetic variability for these species.
