Abstract The genus Piper and Peperomia are the largest genera of Piperaceae and has wide geographical distribution. It is the goal of this study is infer phylogenetic hypothesis of Piper and Peperomia, using different DNA sequences; establish evolutionary trends in the production of classes of secondary metabolites in this genera, employing an array of chemical information built with data from the literature. The regions of the DNA that will be analyzed belong to two genomes of plant cell, which are as follows: matK gene of the chloroplast and ITS gene of the nucleus. The use of molecular markers has huge advance in the phylogenetic studies of Piper and Peperomia. However, there have been no studies on the evolution of secondary metabolites in these genera. In other families, phytochemical data have contributed to clarify phylogenetic relationships. The secondary metabolites are widely diverse in plants, are often used as characters for taxonomic studies. Therefore, it is important to develop studies on Piper and Peperomia on genomic data as the basis for the establishment of evolutionary trends of groups of secondary metabolites. It is possible that one of the results of this research is the establishment of chemical synapomorphies for clades obtained in molecular phylogenetic analysis. | |
