Resumo: | Phylogenetio relationships between Eucalyptus species, subgenus Symphyomyrtus (sections Adnataria, Exsertaria, Maldenaria, and Transversaria), and Corymbia species (sections Politaria and Ocharia) were established based on the sequence of Internal transcribed rDNA spacers (ITS1 and ITS2). The species analyzed were obtained from a collection kept in Brazil. Fragments obtained using primers ITS1 and ITS2 were sequenced and part of the sequence of ITS1 and ITS2 and the complete sequence of 5.8S rDNA were used in the analysis. ITSs and 5.8S rDNA sequences from E. globulus ssp. globulus and A. bakeri (Genus Angophora) were downloaded from the Genbank database and included in the analysis. Psidlum guajava was the selected outgroup used. The sequence alignment and a Neighbor-joining tree were obtained using Clustal X. Few variations were detected in the 5.8S rDNA sequences obtained, occurring mainly between Eucalyptus and Corymbia, thus defining these genera. Variations in ITS sequences occurred in all investigated species. Phylogenetic analysis showed a clear separation between the genera Corymbia and Eucalyptus. A bakeri was more closely related to species belonging to genus Corymbia. Regarding the subgenus Symphyomyrtus (Genus Eucalyptus), only species from section Maidenaria grouped together according to their common section. This could have been caused by the removal of natural reproductive barriers when these species were introduced In Brazil, with a consequent Increase in the rate of interspecific crossings and Introgression events. |
