Chloroplast genomes commonly present a highly conserved quadripartite structure formed by two inverted repeats (IRa and IRb), one large and another small single copy region (LSC and SSC, respectively) 3. This organelle possesses its own genetic material, a circular and double-stranded DNA molecule, comprising about 120 genes (encoding ribosomal RNA, transfer RNA and proteins), and ranging in size between 107–218 kb 2. Its main role is the photosynthesis, but it is also responsible for synthesis of amino acids, fatty acids, lipid components of their membranes and pigments, besides participating in the assimilation of nitrogen 1. The chloroplast is an organelle that belongs to the family of plastids, playing an essential part in plant growth and development. The comparative analyses among species in Malpighiales provided insights into the chloroplast genome evolution in this order, including the presence/absence of three genes ( infA, rpl32 and rps16) and two pseudogenes ( ycf1 and rps19). The phylogenetic reconstruction of Malpighiales with these regions highlighted their utility for phylogenetic studies. We also identified sequences with high divergence that might be informative for phylogenetic inferences in the Malpighiales order, Malpighiaceae family and within the genus Byrsonima. coccolobifolia, both containing 115 genes (four ribosomal RNA genes, 28 tRNA genes and 83 protein-coding genes). Chloroplast genomes ranged between 160,212 bp in B. The chloroplast genomes assembled had a similar structure, gene content and organization, even when compared with species from other families. crassifolia, the first ones described for Malpighiaceae, and performed comparative analyses with sequences previously published for other families in the order Malpighiales. Herein, we sequenced the complete chloroplast genome of B. However, there is no molecular phylogeny available for the genus and taxonomic uncertainties at the generic and family level still remain. Byrsonima is the third largest genus (about 200 species) in the Malpighiaceae family, and one of the most common in Brazilian savannas. ![]()
