1. Microsatellites for detecting inconsistencies in Capsicum cultivars registration in Brazilian database: more than meets the eye
RESUMO No Brasil, o registro de cultivares é feito com cadastramento no Registro Nacional de Cultivares (RNC), o qual, além de habilitar a comercialização do material propagativo da cultivar, garante ao produtor pureza e identidade genética dos propágulos. Mas, é possível que as informações fornecidas para o registro e comercialização das cultiva

2. Molecular diversity in a germplasm collection of avocado accessions from the tropical and subtropical regions of China
Abstract Avocado is an economically important crop and widely cultivated in the tropical and subtropical regions of China, whereas little is known about its genetic diversification. Twenty-six EST-SSR markers were developed based on avocado EST sequences. Molecular characterization was applied to assess the genetic relationships among different accessions.

3. Relationships between land use and water quality obtained for the evaluation of genotoxic effects in plant bioindicators
Resumo As atividades antrópicas bem como o uso e ocupação da terra estão intimamente ligadas à qualidade da água e do solo. Uma alternativa para avaliar suas influências na qualidade da água em corpos hídricos é através do biomonitoramento utilizando Allium cepa como organismo bioindicador. Esta técnica permite detectar anormalidades citogenétic

4. An alternative storage method for characterization of the intestinal microbiota through next generation sequencing
ABSTRACT Gut microbiota has been the subject of various molecular studies mainly due to its importance and wide-ranging relationships with human hosts. However, the storage of fecal samples prior to DNA extraction is critical when characterizing the composition of intestinal microbiota. Therefore, we aimed to understand the effects of different fecal storage

5. A comparison of efficiency parameters of SSR markers and genetic diversity analysis in Amorphophallus paeoniifolius (Dennst.) Nicolson
ABSTRACT Amorphophallus (elephant foot yam) is an herbaceous edible aroid crop which belongs to the family Araceae. The study was undertaken to identify the efficient SSR primer that could differentiate a set of 12 elephant foot yam genotypes. Various efficiency parameters, namely, Polymorphism Information Content (PIC), Marker Index (MI), Resolving Power (R

6. Snake assemblages of Marajó Island, Pará state, Brazil
ABSTRACT We describe the diversity, natural history and structure of snake assemblages from Marajó Island, state of Pará, Brazil, after analyzing 439 specimens deposited in herpetological collections. We tested the hypothesis that snake assemblages from forest and open areas of Marajó Island are distinct with regard to their structure, composition and fun

7. The best of both worlds: Phylogenetic eigenvector regression and mapping
Eigenfunction analyses have been widely used to model patterns of autocorrelation in time, space and phylogeny. In a phylogenetic context, Diniz-Filho et al. (1998) proposed what they called Phylogenetic Eigenvector Regression (PVR), in which pairwise phylogenetic distances among species are submitted to a Principal Coordinate Analysis, and eigenvectors are

8. Capital social en áreas rurales: adaptación al español y validación factorial de una escala
Social capital is considered a structural determinant of social development and wellbeing. Its cognitive component assesses the degree of confidence of the population in their systems for social organization, as well as community interactions to coordinate social responses to social problems. There are few available scales for measuring this construct. This

9. Estudo de estrutura genética da espécie de Cactácea colunar Pilosocereus machrisii utilizando DNA microssatélite
Pilosocereus machrisii is a columnar cacti with natural fragmented distribution; restrict to campos rupestres vegetation patches or rocky outcrops on the Cerrado domain; in Central and eastern Brazil. These features makes P. machrisii an appropriate biological model for population genetic studies aiming to gather information on population structure; since sm

10. Development of an SSR-based identification key for Tunisian local almonds
Ten simple sequence repeat (SSR) loci were used to study polymorphism in 54 almond genotypes. All genotypes used in this study originated from almond-growing areas in Tunisia with different climatic conditions ranging from the sub-humid to the arid and are preserved in the national collection at Sidi Bouzid. Using ten SSR, 130 alleles and 250 genotypes were

11. Genetic variability of brycon orbignyanus (valenciennes, 1850) (characiformes: characidae) in cultivated and natural populations of the upper paraná river, and implications for the conservation of the species
This study aimed to evaluate the genetic variability of B. orbignyanus in cultivated and natural populations of the Upper Paraná River, using molecular RAPD markers and mtDNA control region. Specimens were collected in the Paraná River and in the Piracema fish farm in Maringá, State of Paraná, Brazil. RAPD primers produced 82 loci with consistent express
