“…This can be confirmed by the highest levels of inbreeding observed for the locations from Roraima and Amazonas. Regarding the estimates of genetic diversity, the locations from the Amazon biome presented low values of diversity, similar to data obtained for an aromatic shrub plant species occurring widely in Northeast Brazil, Croton tetradenius (H O = 0.072; H E = 0.086) assessed with SNP markers [27], agreeing with our initial hypothesis. The Cha-padinha location from the Cerrado biome, on the other hand, presented higher genetic diversity indexes, similar to those obtained for mango trees (H O = 0.183-0.215; H E = 0.171-0.216) from seven geographical regions in the world [28].…”

Platonia insignis is a fruit tree native to Brazil of increasing economic importance, with its pulp trading among the highest market values. This study aimed to evaluate the structure and genomic diversity of P. insignis (bacurizeiro) accessions from six locations in the Brazilian States of Roraima, Amazonas, Pará (Amazon biome), and Maranhão (Cerrado biome). A total of 2031 SNP markers were obtained using genotyping-by-sequencing (GBS), from which 625 outlier SNPs were identified. High genetic structure was observed, with most of the genetic variability (59%) concentrated among locations, mainly between biomes (Amazon and Cerrado). A positive and significant correlation (r = 0.85; p < 0.005) was detected between genetic and geographic distances, indicating isolation by distance. The highest genetic diversity was observed for the location in the Cerrado biome (HE = 0.1746; HO = 0.2078). The locations in the Amazon biome showed low genetic diversity indexes with significant levels of inbreeding. The advance of urban areas, events of burning, and expansion of agricultural activities are most probably the main factors for the genetic diversity reduction of P. insignis. Approaches to functional analysis showed that most of the outlier loci found may be related to genes involved in cellular and metabolic processes.
