“…For this reason, it is necessary that sowing for the production of seedlings takes place immediately after the processing of the fruits. The propagation of this species can also occur in vitro from explants, such as the internodal segments (Prudente et al 2016 ). However, this form of propagation is usually only in active germplasm banks.…”

Hancornia speciosa Gomes is a fruit and medicinal tree species native to South America, which in Brazil is considered of potential economic value and priority for research and development. We present a map of the state-of-art, including articles, patents, and molecular data of the species to identify perspectives for future research. The annual scientific production, intellectual, social, and conceptual structure were evaluated, along with the number of patent deposits, components of the plant used, countries of deposit, international classification and assignees, and the accessibility of available molecular data. Brazil has the most significant publications (306) between 1992 and 2020. Technological products (29) have been developed from different tissues of the plant. Most of the articles and patents were developed by researchers from public universities from different regions of Brazil. The molecular data are sequences of nucleotides (164) and proteins (236) of the chloroplast genome and are described to identify the species as DNA barcodes and proteins involved in photosynthesis. The compilation and report of scientific, technological, and molecular information in the present review allowed the identification of new perspectives of research to be developed based on the gaps in knowledge regarding the species and perspectives for the definition of future research. Supplementary Information The online version contains supplementary material available at 10.1007/s10722-021-01319-w.

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).

“…Despite efforts to develop a reliable protocol for in vitro establishment and shoot multiplication for H. speciosa [12,20,[38][39][40], there is no research regarding the SV at the molecular level focused on this species. Accessing the genetic stability of plantlets recovered by tissue culture techniques at early stage through molecular markers is recommended since morphological variations in plants raised through tissue culture can be detected usually at later stages [41].…”

The plant tissue culture procedures for asexual multiplication of Hancornia speciosa represent an important process facilitating the preservation of selected genotypes of this threatened species and large-scale production of plantlets for population reinforcement or other utilization. However, there is no research regarding the somaclonal variation of this threatened species at molecular level. This study aimed to evaluate the role of the multiplication process in the genetic stability of H. speciosa plantlets and calluses using molecular markers. The tissue culture techniques for H. speciosa micropropagation used in this study did not influence the occurrence of somaclonal variation, which can be related to the genotypes of the donor plants and to the low concentrations of growth regulators used in tissue culture procedures adopted. The results observed here provide a reliable methodology for further studies involving micropropagation techniques with the goal of preserving selected or endangered genotypes of H. speciosa without genetic losses and producing seedlings of this species on a large scale. In addition, it was possible to verify that the donor plants used in this study showed a relatively low genetic variability.
