“…The identification of private alleles is useful for genetic conservation [ 55 ]. In the present study, the populations from APD (Ap = 40), AR1 (Ap = 35), and MOS (Ap = 28) had the highest number of private alleles and diversity was not found in the other localities; therefore, these populations deserve special management because the levels of private alleles are indicative of individual fitness and explain the evolutionary potential of populations and their ability to adapt to the adverse environmental conditions [ 21 ].…”

Population genomics of the neotropical palm Copernicia prunifera (Miller) H. E. Moore: Implications for conservation

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.

“…For this reason, there is still no consensus on the taxonomy of this genus [22]. Recent studies using both morphoanatomical characteristics of the plant and fruit biometrics have contributed to the understanding of the taxonomy of this group [23][24][25][26][27].…”

“…Macauba, like most palm species, has an essentially extractive cultivation system, leading to habitat fragmentation, increasing inbreeding, and decreasing genetic diversity [37]. Both the domestication process and the development of breeding programs for A. aculeata are still at an incipient stage [27,38] should be integral and systematic due to the socioeconomic impact of the cultivation of this palm and the application prospects [7]. The success of the domestication process depends on genetic improvement programs that are directly related to the choice of genotypes with the best agronomic characteristics [39].…”

The global production of vegetable oil has increased since the beginning of the century, reaching a peak of 209 million tons in 2020/2021 and is projected to continue to increase due to population growth and the impact of the biodiesel industry. In this context, palm oil and soybean oil have stood out. However, both palm oil and soybean oil production chains are not fully sustainable, leading to socioeconomic and environmental challenges, which have driven the search for new raw materials with sustainability potential. Macauba [Acrocomia aculeata (Jacq.) Lodd. Ex Mart.] is an oleaginous palm distributed mainly in Central and South America, and most of the Brazilian territory. It is one of the species with greater potential for economic exploitation due to its high oil productivity and use of by-products from oil extraction and processing. This chapter addresses the most up-to-date information in biology, oil production, and oil processing from fruit to oil applications.

“…• Genetic characterization and plant breeding. Knowledge of A. aculeata has been expanded by the genetic and biometric characterization of germplasm from natural populations in various regions of Brazil, progress in molecular biology information on the species, the study of its reproductive biology, and the establishment of germplasm banks [6,12,[60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77]. This has allowed the identification of promising genetic material for selection.…”

The diversification of biomass resources is key to the transition towards a bioeconomy. Acrocomia spp., a neotropical genus of palms, is an example of plants’ diversity potential for a sustainable bioeconomy. Acrocomia’s adaptability to environments outside rainforests, its specific fruit properties and high yields has generated the interest of researchers and entrepreneurs, triggering its introduction as a multipurpose oil crop. Developing sustainability-oriented and knowledge-based acrocomia value webs requires a collaborative, systems approach from the outset. Fostering an inter- and transdisciplinary dialogue on acrocomia through a participatory workshop with both academic and non-academic actors contributed to this endeavor. This allowed the identification of priorities, knowledge gaps, and stakeholder roles, and served as the basis for the co-creation of a research and development roadmap. Key steps for the introduction of acrocomia include intertwined technical aspects relating to the development of planting material, cultivation systems, processing technologies and applications, market entry, and value web governance aspects. A broad collaboration among scientists, the public and private sectors, farmers, and civil society, is required for the development of acrocomia value webs. The incorporation of sustainability and a consideration of context in the design and development phases are fundamental to fostering the sustainable performance of acrocomia value webs.
