摘　　要：Annona cherimola is a woody perennial species in the Annonaceae family that produces edible fruits and has economic importance in several regions of the world with subtropical climates.Together with other 10-12 species,A.cherimola belongs to the section Atta of the Annona genus with a center of origin in Central America and the Caribbean.Species of the section Atta produce soft skin ripe fruits with raised areoles bounded by recessed furrows.Annona cherimola is the only species of the section naturally found in the Andean region of South America.Currently,no information is available at the molecular level on the phylogenetic relationships of most of the species of Atta and closely related sections in Annona.In order to fill this gap,in this work a phylogenetic approach was performed using five coding and non-coding plastid DNA regions,to determine the phylogenetic relationshipsbetween A.cherimola and other related species included in Atta and other sections of the genus.The results obtained support recent studies that demonstrated the likely Mesoamerican origin of A.cherimola based on biogeographical analysis with SSR markers,rather than the previously considered South American origin hypothesis.In addition,the species belonging to the Atta section did not show monophyly.Finally,A.cherimola andA.pruinosa seem to be phylogenetically close species and additional studies are needed to discern the relations between them.
