“…It occurs in the tableland and coastal plains of the Northeast, in the Cerrado of the Central-West, in the North and Southeast regions of Brazil. The state of Sergipe is the largest mangaba producer in the country, especially in the municipalities of Barra dos Coqueiros, Itaporanga D'Ajuda, and Estância (Soares et al, 2016). The deforestation of large areas of natural occurrence of the species provides the genetic erosion of mangaba, and associated with this, the unsustainable use of remaining individuals result in irreparable environmental damage (Santos et al, 2010).…”

The state of Sergipe is the largest mangaba producer, which is a fruit native to Brazil, and has cultural, social and economic importance in its area of occurrence. It is an endangered species due to human actions, and despite its economic potential, there are still no commercial plantations. The study was carried out in order to characterize trees, fruits and the genetic diversity of natural populations of mangaba in Sergipe, Brazil. Fruits from Abaís Beach/Estância (AB) presented, on average, twice the vitamin C content (414.81 mg of vit. C/100g), when compared with the others. The use of ISSR primers was efficient in estimating the genetic similarity of populations. The primers clustered the populations of mangaba according to their origin, which indicates the genetic diversity of mangaba and their isolation. The results can be used to guide the selection of individuals in situ and ex situ conservation actions of these genetic resources. Index terms:Hancornia speciosa Gomes; postharvest; molecular markers; variability. RESUMOO Estado de Sergipe é o maior produtor de mangaba, fruta nativa do Brasil e de importância cultural, social e econômica nas áreas de ocorrência. Encontra-se em risco de extinção devido a ações antrópicas, e apesar de seu potencial econômico, ainda não existem plantios comerciais da espécie. O trabalho foi desenvolvido com o objetivo de caracterizar árvores, frutos e a diversidade genética de populações naturais de mangabeira em Sergipe, Brasil. Frutos oriundos de Abaís/Estância (AB) apresentam em média o dobro do conteúdo de vitamina C (414.81 mg de vit. C/100g) dos demais. O uso de primers ISSR foi eficiente para estimar a similaridade genética das populações, sendo agrupados de acordo com sua origem, o que indica a diversidade genética destas mangabeiras, e seu isolamento. Os resultados poderão ser usados para direcionar a seleção de indivíduos em ações de conservação desses recursos genéticos, in situ e ex situ.

“…Therefore, inside the germplasm bank progenies hybridization may occur due to natural pollinator agents. Soares et al (2016) carried out the test with 155 mangaba individuals of natural species from Sergipe, concluding 100% of polymorphism presenting high genetic variability among populations. The rate of genetic similarity of this study was considered low when compared with the study on natural species, the fact of the matrices belonging to the BAG, factors such as geographical proximity of the accessions and the position of the matrices in the experimental field, interfere in genetic diversity between matrix/progeny.…”

Mangaba tree (Hancornia speciosa Gomes) is a tropical fruit species from Brazil and presents socioeconomic potential. The objective of this study was to determine antioxidant activity, rutin content and genetic similarity among in vivo and in vitro matrices and progenies of six accessions from the Mangaba Active Germplasm Bank of the Embrapa Coastal Tablelands, SE, Brazil. Young leaves of adult matrix plants and in vitro callus methanolic extracts obtained from young leaves resulted in differences between the accessions for the rutin content and high antioxidant activity. The Costa Azul accession, from Bahia, Brazil outstood with values above 3,000 g of dry extract/g of DPPH (2.2-diphenyl-1-picrilhydrazyl) in in vitro callus coming from nodal and internodal segments (3,023.73 and 3,136.80 g of dry extract/g of DPPH, respectively). Rutin was not found in extracts resulting from in vitro callus of mangaba tree. The difference among the values obtained for DPPH analysis are superior when compared with in vivo leaf extract, with the in vitro Costa Azul accession (nodal and internodal) outstanding, concluding that in vitro callus induction can interfere with chemical compounds of the plant. The markers detect genetic similarity under in vitro cultivation conditions. The Costa Azul accession group itself in isolation from others and EC 50 concentrations differentiated between leaf and callus are obtained. O EC 50 is superior in extracts deriving from in vitro callus, with the in vitro Costa Azul accession (nodal and internodal).

Mangaba (Hancornia speciosa Gomes -Apocynaceae) is a native fruit of Brazil which is of great importance in its areas of occurrence. This species has been subjected to habitat fragmentation that is mainly due to human activity, and requires conservation. The aim of the present review was to evaluate the biotechnological advances in the species. This paper deals with recent studies on the genetic diversity and bioactive compounds.
