“…One of the many factors contributing to the generation of unviable seeds and seedlings is inbreeding, especially in forest species, since most of them reproduce by cross-fertilization (Shimizu, 2007). Knowing the genetic variability existing in these populations affected by human activity can contribute to the development of an adequate management on these populations and recovery of degraded environments (Rabbani et al, 2012).…”

ABSTRACT. Poincianella pyramidalis (Tul.) L.P. Queiroz is an endemic Caatinga (Brazilian savannah biome) species that has been exploited for different purposes, although information is necessary about still existing natural populations. The objective of this study was to evaluate the genetic diversity among 20 P. pyramidalis individuals occurring in a population localized in the Caatinga biome of Paraíba State, aiming at seed collection, using RAPD markers. For the DNA extraction, young shoots of the individuals were used, and amplification was carried out using 20 primers. The obtained markers were converted to a binary matrix, from which a genetic dissimilarity matrix was built using the arithmetic complement of Jaccard's coefficient, and the dendrogram was built by the UPGMA analysis. No amplified fragment was monomorphic, resulting in 100% polymorphism of the analyzed population. The mean genetic diversity among the matrices was 63.28%, ranging from 30.9 to 97.7%. Individuals 09 and 17 showed relevant genetic proximity, and thus planting their seedlings at close sites would not be indicated. The population evaluated in this study showed high genetic diversity, originating twelve groups from the UPGMA hierarchical cluster analysis. Based on the results, individuals 09 and 17 can provide plant material for the evaluation of the physiological performance of P. pyramidalis seeds, and the set of individuals of this population has a high genetic diversity that characterizes them as adequate matrices for projects of restoration and conservation of the seed species.

“…Diante do cenário de devastação das áreas, estudos que contemplem os genótipos prioritários para conservação são poucos. Em Sergipe, poucos trabalhos abordam o tema (SANTANA et al, 2008;GOIS;SILVA-MANN;FERREIRA, 2009;RABBANI;SILVA-MANN;FERREIRA, 2012). Estudos desse tipo, além de outros envolvendo aspectos biológicos, moleculares, econômicos, culturais e sociais tornam-se necessários tanto em nível nacional, quanto regional e local (MELO, 2007).…”

“…A atividade contra Staphylococus aureus e Streptococcus pyogenes, confirmam, em alguns casos, as propriedade antibacterianas conhecidas pela medicina popular para essa espécie (VIRTUOSO et al, 2005). Estudos realizados com o mulungu têm permitido o isolamento de novos compostos, e alguns deles nunca tinham sido isolados de uma planta dessa espécie, ou até mesmo da família Fabaceae (RABELO et al, 2001), atribuindo assim novas propriedades para essa espécie. Com os estudos apresentados verifica-se um potencial biotecnológico da espécie para produção de fitoterápicos e fitofármacos.…”

Caracterização genética de mulungu (Erythrina velutinaWilldPalavras-chave: Genética vegetal. Mulungu. ABSTRACT -The coral tree (Erythrina velutina Willd.), popularly known in Brazil as mulungu, presents various pharmacological properties and although extremely scarce, can be found in regions of the State of Sergipe, Brazil. Due to economic interests, producing information in order to set up plans for its conservation and sustainable exploitation becomes essential. The objective of this work was to characterize individuals of Erythrina velutina by means of ISSR markers. In order to do this, 40 individuals were studied from three locations in the State of Sergipe (The town of Pinhão -Caatinga; The towns of Santana do San Francisco and São Cristóvão -Atlantic Forest). In total, 149 loci from 11 ISSR primers were obtained and evaluated. The minimum number of loci for the study of diversity in E. velutina was 117, agreeing with Kruskal's stress value. Spatial genetic structuring is seen in the population from Santana, but the population from Pinhão lacks this structuring; its individuals are distributed randomly, compromising sustainability over time and therefore requiring immediate action for its conservation and restoration.

“…According to Rabbani, Silva-Mann, and Ferreira (2012), G. americana presents an economic importance for the production of food, since its consumed in natura or used for the production of sweets, jellies and liqueurs (Lorenzi, 1992). The fruits have numerous seeds, which are found together in the innermost part of the nucleus (Figueiredo, Maia, Monteiro, & De-Figueiredo, 1991).…”

Genipa americana L. well known as genipap, is a tree that is widely distributed throughout the Brazilian territory. The communities appreciate the genipap fruits, since they are used as food; in addition to that, their fruits have numerous seeds that can be used in the production of vegetable oil. This being, in this work inclined to a bromatological study of the genipap fruits and chemical composition and bioassays from vegetable oil seeds. Obtaining the highest percentage of lipids in the seeds that was of 7.08%, the highest percentage of humidity obtained was 74.66% present in the pulp, the highest amount of carbohydrates was found in the seeds, with a percentage of 79.37%, the highest percentage of ash present was 3.99% found in the pulp, another parameter analyzed were the proteins mostly present in the seeds with a percentage of 4.45% and finally the energy value was calculated, being the majority in the seeds with 398.98 Kcal/100 g. The fatty acid profile showed the highest percentage for the Linoleic Acid with 61.5%. The greatest inhibition in the antimicrobial assays was for S. typhimurium with 42.12% inhibition. In the tests performed for the inhibition of the enzyme acetylcholinesterase was 14.95%.
