Abstract

The nature and number of characters used for the identification and systematization of plants have increased and changed greatly throughout the history of plant classification, especially with the advent of DNA discovery and the use of molecular techniques for their study. Analyzes based on molecular data, in increasing and rapid progress, associated with morphological data are excellent sources of information for evolutionary and phylogenetic reconstruction studies. The palm trees (Arecaceae) have the highest morphological diversity within monocotyledons, being represented by about 2,700 species distributed in more than 240 genera, constituting one of the most characteristic groups of tropical flora, with great economic, social and ecological importance. Thus, the present project proposes the execution of an in - depth study of the external morphology, leaf anatomy and, molecular, with use of chloroplastid, nuclear, and SNPs markers in the Acrocomia palms, a taxonomically unresolved genus distributed throughout Tropical and Subtropical Americas, widely used for oil production and with great potential for use in other segments, in order to reconstruct phylogenetic hypotheses that allows the interpretation of the evolution of characters important to its circumscription. The results to be obtained with the present proposal, which unites knowledge of different areas, will contribute to future studies including their use, conservation and, above all, their breeding, including the correct identification and characterization of the individuals used for the formation of the Acrocomia Germplasm Bank in current implantation in the Institution (FAPESP 14/23591-7).
