Abstract The Cerrado, the largest Neotropical savanna, and Brazilian Atlantic Forest form large ecotonal areas where savanna forest habitats occupy adjacent patches with closely related species occurring side by side, providing opportunities for hybridization. Here, we investigated evolutionary divergence between ecotypes of widely distributed tree Plathymenia reticulata ( n = 233 individuals). Genetic structure analysis P . was congruent recognition two ecotypes, whose captured proportion...
Abstract Local adaptation is often a product of environmental variations in geographical space and has implications for biodiversity conservation. We investigated the role latitudinal heterogeneity climate on organization genetic phenotypic variation dominant coastal tree Avicennia schaueriana . In common garden experiment, samples from an equatorial region, with pronounced seasonality precipitation, accumulated less biomass, showed lower stomatal conductance transpiration, narrower xylem...
Environmental variation along the geographical space can shape populations by natural selection. In context of global warming and changing precipitation regimes, it is crucial to understand role environmental heterogeneity in tropical trees adaptation, given their disproportional contribution water carbon biogeochemical cycles. Here, we investigated how freshwater availability wetlands has influenced molecular variations black mangrove (Avicennia germinans). A total 57 were sampled at seven...
The goal of this research was to generate networks co-expressed genes explore the genomic responses Rhizophora mangle L. populations contrasting environments and use gene network analysis investigate their capacity for adaptation in face historical future perturbations climatic changes. RNA sequencing data were generated R. samples collected under field conditions from climate zones equatorial subtropical regions Brazil. A co-expression constructed using Pearson's correlation coefficient,...
Abstract Assessing the relative importance of geographical and environmental factors to spatial distribution genetic variation can provide information about processes that maintain in natural populations. With a globally wide but very restricted habitat distribution, mangrove trees are useful model for studies aiming understand contributions these factors. Mangroves occur along continent–ocean interface tropical subtropical latitudes, regions considered inhospitable many other types plants....
Twenty-seven nuclear microsatellite markers were developed for the mangrove fern, Acrostichum aureum (Pteridaceae), to investigate genetic structure and demographic history of only pantropical plant.Fifty-six A. individuals from three populations sampled genotyped characterize 27 loci. The number alleles expected heterozygosity ranged one 15 0.000 0.893, respectively. Across 26 polymorphic loci, Malaysian population showed much higher levels polymorphism compared other two in Guam Brazil....
Microsatellite loci were isolated and characterized for use in population genetic studies of Plathymenia reticulata (Fabaceae), a tropical tree widespread the Atlantic Forest cerrado biomes South America.Nine microsatellite markers developed using simple sequence repeat-enriched library. Polymorphism was analyzed 51 individuals from two populations. All polymorphic, with number alleles per ranging five to 15 (mean alleles: 10.22). Observed expected heterozygosities ranged 0.313 1.000 0.280...
Abstract Local adaptation is often a product of environmental variations in the geographical space and has implications for biodiversity conservation. We investigated role latitudinal heterogeneity climate on organization genetic phenotypic variation dominant coastal tree, Avicennia schaueriana . In common garden experiment, samples from an equatorial region, marked by rainy/dry seasons, accumulated less biomass, showed lower stomatal conductance transpiration, narrower xylem vessels,...
ABSTRACT Mangroves are coastal ecosystems of great socioenvironmental importance that highly threatened by human activities. Mangrove trees live under harsh environmental conditions, which makes them sensitive to extreme weather events, particularly freezing events. Such events unpredictable and have catastrophic consequences for mangrove trees; therefore, understanding anticipating the impacts such essential directing future mitigation measures. Freezing cold currently limits distribution...

Oral cancer is the seventh most frequent type in our population and approximately 90% of these malignancies are squamous cell carcinoma. Genetic alterations tumor suppressor genes increase risk development, since associated with cycle control. Epigenetic changes involving regulatory related to initiation progression various tumors. The hyper methylation gene p16 found many types cancers silencing. aim this study was determine promoter region samples normal oral mucosa from patients technique...
Genomic profiling using next-generation sequencing (NGS) is fundamental for driving prognostic and therapy in cancer. Formalin-fixed paraffin embedded (FFPE) tissue the widely used material, whereas non-FFPE may represent an alternative. However, studies comparing NGS performance of materials to FFPE are still lacking literature. The objective this study was characterize preparations nucleic acid yield on both a capture-based amplicon-based platform. quality metrics obtained from were compared FFPE.
Abstract Environmental variation along the geographical space can shape populations by natural selection. In context of global warming, accompanied substantial changes in precipitation regimes, it is crucial to understand role environmental heterogeneity tropical trees adaptation, given their disproportional contribution water and carbon biogeochemical cycles. Here we investigated how freshwater availability wetlands has influenced molecular variations Black-Mangrove ( Avicennia germinans )....
Abstract Geographic and environmental differences have been identified as factors influencing Brazilian mangrove trees’ genetic diversity. Geographically, distinct species convergent spatial structures, indicating a limited gene flow between northern southern populations. Environmentally, genomic studies common garden experiments found evidence of local adaptations along the latitudinal gradient coast. However, little is known about how such adaptive heterogeneity could be affected by...
