“…However, the use of this marker requires the previous development of loci, which do not exist for E. precatoria, and this process is laborious and expensive (Gupta et al, 2016). The conservation of microsatellite sites among related species makes it possible to transfer them to other species (Guidugli et al, 2010;Santos et al, 2011, Carmo et al, 2015, Azêvedo et al, 2016Fagundes et al, 2016). To date, 18 SSR loci have been developed for Euterpe edulis, seven of which have been shown to be amplifiable and polymorphic for E. oleracea (Gaiotto et al, 2001;Oliveira et al, 2010).…”

Euterpe precatoria, popularly known as "açaí-doamazonas", has agronomic, technological and economic potential and has been gaining prominence with the commercialization of its fruits. The production of this açaí-do-amazonas is based on extractivism and management practices have been recommended for sustainable collection. To recommend sustainable rates of fruit collection, it is essential to have information on the genetic variability of natural populations to monitor the recruitment and population dynamics. The objective of this study was to evaluate the transferability of microsatellite loci of E. edulis species to E. precatoria to confirm the applicability of these markers in genetic studies. Eighteen microsatellite loci developed for E. edulis were analyzed using 20 individuals from two natural populations (Formoso and Novo Segredo) of E. precatoria collected at Feijó, State of Acre, Brazil. All loci (100%) were amplified, and of these, nine (50%) were polymorphic. A total of 29 alleles were Genetics and Molecular Research 16 (4): gmr16039825 found in the Novo Segredo population, and 27 alleles were found in the Formoso population, ranging from two to five alleles per locus, with a mean of three alleles per locus. The expected heterozygosity in the Formoso population varied from 0.100 to 0.668, with an average of 0.421. In the Novo Segredo population, a variation between 0.100 and 0.710, with a mean of 0.418, was found. The observed heterozygosity values ranged from 0.100 to 0.800, with averages of 0.333 and 0.267 for Formoso and Novo Segredo, respectively. This set of markers will support further studies on the molecular characterization of the natural populations of E. precatoria and assist with the recommendation of sustainable management practices and strategies for the conservation and genetic improvement of this species.

Arachis pintoi, commonly known as pinto or forage peanut, is used mainly in consortia with grass pastures and as cover plant. In addition to increasing the productivity of livestock and plantations, it contributes to the mitigation of environmental impacts (reduction of greenhouse gas emissions) and soil improvement (nitrogen fixation, reduction of fertilizers use), as well as to pests and disease management. Several cultivars that are tolerant to specific climates and soil conditions are suitable to be used as ground covers in agroforestry and silvopastoral systems, orchards, and plantations. Biotechnological and phytochemical investigations revealed the potential of pinto peanut as a sustainable source of resveratrol and other stilbenoids. Extracts from plants grown under natural conditions and from materials obtained in vitro displayed allelopathic, anthelmintic, or antioxidant activities. Other studies revealed the potential of pinto peanut for erosion control, phytoremediation, seed and essential oils production, materials for animal tissue engineering, synthesis of nanoparticles for drug delivery, and as green biorefineries to produce proteins, biochemicals, and biomaterials.
