“…Copernicia prunifera (Mill.) H.E.Moore, known as Carnaúba (Carnaúba palm), is a worldwide source of quality carnauba wax 16,17 and can also be used in cosmetics, skin care and candy coating 18 . Both palms are endemic to Brazilian biomes, Pantanal and Caatinga, respectively.…”

“…For B. gasipaes, the rst chloroplast genome was assembled and used to make inferences within the tribe Cocoseae 20 . In the Brazilian Northwest, 11 natural populations of C. prunifera were analyzed using Inter Simple Sequence Repeats (ISSR) markers, in which genetic bottlenecks were detected due to wax extracting, land-use change for wind power expansion and agriculture decreasing natural habitat 17,21 . For S. romanzo ana, a recent study using SSR (single sequence repeats) markers detected low diversity in speci c genetic parameters, emphasizing the need of increasing genetic research within this species 22 .…”

The Arecaceae family has a worldwide distribution, specially in the tropical and subtropical regions. We sequenced the chloroplast genome of Acrocomia intumescens and A. totai, widely used in the food and energy industry, Bactris gasipaes, important for palm heart, Copernicia alba and C. prunifera, worldwide known for wax utilization, and Syagrus romanzoffiana, of great ornamental potential. Copernicia spp. showed the largest chloroplast genomes (C. prunifera: 157,323 bp and C. alba: 157,192 bp), while B. gasipaes presented the smallest (155,078 bp). Copernicia spp. had two more gene copies (trnL-GAG) than the others, and S. romanzoffianaunderwent pseudogenization in one copy of rps19. Structurally, great synteny was detected among palms. Conservation was also observed in the distribution of single sequence repeats (SSR). Copernicia spp. presented less dispersed repeats, without occurrence in the small single copy (SSC). All RNA editing sites were C (cytidine) to U (uridine) conversions. Overall, closer phylogenetically species shared more sites. Almost all nodes of the phylogenetic analysis showed posterior probability (PP) of 1.0, reaffirming the close relationship between Acrocomia species. These results elucidate the conservation among palm chloroplast genomes but point to subtle structural changes, providing support for the evolutionary dynamics of the Arecaceae family.

“…The fruits serve as food for animals, the stems can be used in the construction of houses, and the fasciculated roots have medicinal properties [ 14 ]. Due to its versatility and usefulness, this palm tree is known as “the tree of life” [ 15 ]. The main product of economic value obtained from this tree is carnaúba wax, which is extracted from young leaves and is of interest in the pharmaceutical and automotive industries [ 16 ].…”

Copernicia prunifera (Miller) H. E. Moore is a palm tree native to Brazil. The products obtained from its leaf extracts are a source of income for local families and the agroindustry. Owing to the reduction of natural habitats and the absence of a sustainable management plan, the maintenance of the natural populations of this palm tree has been compromised. Therefore, this study aimed to evaluate the diversity and genetic structure of 14 C. prunifera populations using single nucleotide polymorphisms (SNPs) identified through genotyping-by-sequencing (GBS) to provide information that contributes to the conservation of this species. A total of 1,013 SNP markers were identified, of which 84 loci showed outlier behavior and may reflect responses to natural selection. Overall, the level of genomic diversity was compatible with the biological aspects of this species. The inbreeding coefficient (f) was negative for all populations, indicating excess heterozygotes. Most genetic variations occurred within populations (77.26%), and a positive correlation existed between genetic and geographic distances. The population structure evaluated through discriminant analysis of principal components (DAPC) revealed low genetic differentiation between populations. The results highlight the need for efforts to conserve C. prunifera as well as its distribution range to preserve its global genetic diversity and evolutionary potential.
