Do tropical plants have smaller genomes? Correlation between genome size and climatic variables in the Caesalpinia Group (Caesalpinioideae, Leguminosae)
While a number of studies have suggested that temperate plants typically have larger genome sizes (GS) than tropical ones, recent analyses have not convincingly confirmed this. We have selected the widely distributed Caesalpinia Group (Leguminosae) to test this hypothesis. We used flow cytometry to estimate the amount of DNA in...Souza, Gustavo ; Costa, Lucas ; Guignard, Maïté ; Van-Lume, Brena ; Pellicer, Jaume …

Evolutionary convergence or homology? Comparative cytogenomics of Caesalpinia group species (Leguminosae) reveals diversification in the pericentromeric heterochromatic composition
The Caesalpinia Group includes 225 species and 27 monophyletic genera of which four occur in Northeastern Brazil: Erythrostemon (1 sp.), Cenostigma (7 spp.), Libidibia (1 sp.), and Paubrasilia (1 sp.). The last three genera are placed in different clades in the Caesalpinia Group phylogeny, and yet they are characterized by...
