dc.description.abstractThe Hymenaea clade is a lineage of the subfamily Detarioideae of Leguminosae. The clade is currently composed of three genera: Guibourtia, Hymenaea, and Peltogyne. The genera Guibourtia and Hymenaea present an AmphiAtlantic distribution, whereas Peltogyne is exclusively found in the Neotropics. Previous studies have focused on the phylogeny of the group but there are no studies that demonstrate mechanisms that could be involved in the evolution of this Amphi-Atlantic clade. The present work is the largest cytogenetic analysis for the group published so far. We aimed to provide a study of karyotypic characteristics of the Hymenaea clade, interpreted using the plastidial trnK phylogenetic reconstruction as background. We analyzed karyological characteristics such as chromosome number, chromosome size, centromeric position, CMA/DAPI patterns, and banding for 5S and 45S rDNA. With the present data available, multivariate analyses (PCA) and Phylogenetic Eigenvector Regression (PVR) demonstrated that centromeric asymmetry and number of 5S rDNA sites may present a strong phylogenetic signal, whereas number of CMA+ sites is associated with geography/climate characteristics. The association of CMA bands and geography has been reported for other legumes of the Caesalpinia group. This study demonstrates that the use of statistical tools for analyzing karyotypic characteristics can result in more precise interpretation of evolutionary processes related to structural changes in chromosomes and how these changes can also be related to environmental conditions.pt_BR
