Resumo: | Dorstenia, the second largest genus of Moraceae, comprises nine sections that are mainly found in Africa and America. Two of them are woody macrospermous, and the other seven are herbaceous microspermous. There are three sections in the Neotropics, all of which are herbaceous and taxonomically complex owing to their great morphological similarity. The most recent molecular phylogenetic studies of Dorstenia suggested that the neotropical sections are polyphyletic. These studies also showed that the neotropical species represent a sister group to an African woody macrospermous grade rather than African herbaceous microspermous plants. We have now expanded the number of taxa sampled and included other molecular markers to determine whether the previous phylogeny are to be corroborated or whether new taxonomic interpretations are to be followed. This study inferred the phylogeny of the group based on ITS, ETS, and trnL-F regions from 40 of the 58 neotropical species and added a new African taxon, thus including 17 of the 60 known species. Our results reaffirmed the polyphyletic nature of the neotropical sections. Dorstenia sect. Acauloma emerged within the main clade of D. sect. Kosaria (both African species), a result that confirms the affinity of these taxa already observed in previous morphological studies. We suggest Dorstenia sect. Dorstenia as the only neotropical section. |

Duas delas são macrospermas lenhosas e os outros sete são microspermas herbáceas. Existem três seções na região Neotropical, todas herbáceas e taxonomicamente complexas devido à sua grande semelhança morfológica. Os estudos filogenéticos moleculares mais recentes sugerem que as seções neotropicais são polifiléticas. Esses estudos também mostraram que as espécies neotropicais representam um grupo irmão de um grado de macrospermas lenhosos africanos, em vez de microspermas herbáceos. No presente trabalho, expandimos o número de taxa amostrados e incluímos outros marcadores moleculares para determinar se a filogenia anterior deve ser corroborada e se novas interpretações taxonômicas devem ser seguidas. Este estudo inferiu a filogenia do grupo com base nas regiões ITS, ETS e trnL-F de 40 das 58 espécies neotropicais e adicionou um novo táxon africano, incluindo 17 das 60 espécies conhecidas. Nossos resultados reafirmaram a natureza polifilética das seções neotropicais. Dorstenia sect. Acauloma surgiu dentro do clado principal de D. sect. Kosaria (ambas espécies africanas), resultado que confirma a afinidade desses táxons já observada em estudos morfológicos anteriores. Nós sugerimos Dorstenia sect. Dorstenia com a única seção neotropical, porém maiores estudos moleculares são necessários.2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://hdl.handle.net/10316/101180http://hdl.handle.net/10316/101180https://doi.org/10.1590/2175-7860202172087eng2175-78600370-6583Vianna-Filho, Marcelo Dias MachadoPederneiras, Leandro CardosoMaia, Vitor HugoCosta, Andrea Ferreira daMansano, Vidal de Freitasinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-08-16T20:49:39Zoai:estudogeral.uc.pt:10316/101180Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:18:25.800728Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
