13. Molecular characterisation of
Aspergillus flavus isolates from peanut fields in India using AFLPAflatoxin contamination of peanut, due to infection by
Aspergillus flavus , is a major problem of rain-fed agriculture in India. In the present study, molecular characterisation of 187Aspergillus flavus isolates, which were sampled from the peanut fields of Gujarat state in India, was performed using AFLP markers. On a poBraz.

14. Developing a common bean core collection suitable for association mapping studies
Because of the continuous introduction of germplasm from abroad, some collections have a high number of accessions, making it difficult to explore the genetic variability present in a germplasm bank for conservation and breeding purposes. Therefore, the aim of this study was to quantify and analyze the structure of genetic variability among 500 common bean a

15. Diversity and genetic structure of jenipapo (Genipa americana L.) Brazilian accessions
Usually known as jenipapo, Genipa americana L. is a Rubiaceae Brazilian native species. It is an important species in the restoration of Brazilian riparian forests and is one of the most promising fruit trees for sustainable harvesting programs. In this study we provide the first data on the genetic diversity and structure of a Jenipapo Germplasm Bank using

16. Genetic diversity and structure of Atta robusta (Hymenoptera, Formicidae, Attini), an endangered species endemic to the restinga ecoregion
The genetic diversity and structure of the ant Atta robusta were assessed by ISSR (inter-simple sequence repeats) in 72 colonies collected from 10 localities in the Brazilian states of Espírito Santo (48 colonies) and Rio de Janeiro (24 colonies). The ISSR pattern included 67 bands, 51 of them (76.1%) polymorphic. Analysis of molecular variance (AMOVA) reve

17. Genetic variation in cultivated Rheum tanguticum populations
To examine whether cultivation reduced genetic variation in the important Chinese medicinal plant Rheum tanguticum, the levels and distribution of genetic variation were investigated using ISSR markers. Fifty-eight R. tanguticum individuals from five cultivated populations were studied. Thirteen primers were used and a total of 320 DNA bands were scored. Hig

18. Genetic diversity and population structure of bocachico Prochilodus magdalenae (Pisces, Prochilodontidae) in the Magdalena River basin and its tributaries, Colombia
Prochilodus magdalenae is an endemic freshwater fish that occurs in the Magdalena, Sinú and Atrato hydrographic basins. It has an important economic role and is a food resource for the artisanal fishing communities. Its socioeconomic importance contrasts with the current status of its fisheries, where stocks are being depleted. Considering its importance an

19. Perfil proteômico muscular de bovinos inteiros da raça Nelore / Muscle proteomic profile of Nellore bulls
The present work aimed to study beef quality (Longissimus dorsi) from Nellore bull through two-dimensional proteomic analysis. For this purpose, two specific objectives were proposed: (i) to study the proteolysis of meat at different aging times, if 24 hours, seven and 14 days, and (ii) to study the protein profile of meat from Nellore bull with contrasting

20. Estudo da influência da adição de etanol e/ou metanol ao biodiesel associado a ferramentas quimiométricas
The objective of this work is to study the influence of the addition of alcohol methanol or ethanol - to biodiesel. Therefore, Principal Components Analysis (PCA) was combined with infrared spectra with the aim of separating soybean and tallow biodiesel samples with different alcohol contents of ethanol or methanol. PCA yielded a good reduction of data regar

21. Levan from Bacillus subtilis Natto: its effects in normal and in streptozotocin-diabetic rats
Levan is an exopolysaccharide of fructose primarily linked by β-(2→6) glycosidic bonds with some β-(2→1) branched chains. Due to its chemical properties, levan has possible applications in both the food and pharmaceutical industries. Bacillus subtilis is a promising industrial levan producer, as it ferments sucrose and has a high levan-formation capaci

22. Relaciones entre los bovinos criollos panameños y algunas razas criollas de Latinoamérica
The objective of this work was to establish the genetic relationship between Guabalá and Guaymi cattle populations and some native ones of Latin America. Factorial correspondence analysis, analysis of molecular variance, genetic distances, average number of migrants per population and Wright's F statistics were performed. Population structure was assessed b

23. Diversidade genética da abelha Eufriesea violacea (Hymenoptera, Apidae, Euglossini)
In this study six populations of Eufriesea violacea had their genetic structure and diversity estimated using microsatellite markers and mitochondrial obtained by PCR-RFLP. The samplings of male bees were carried out in Atlantic Forest remnants located in the states of Paraná (PR1, PR2, and PR3), São Paulo (SP1), Santa Catarina (SC1) and Rio Grande do Sul

24. Genetic diversity analysis of common beans based on molecular markers
A core collection of the common bean (Phaseolus vulgaris L.), representing genetic diversity in the entire Mexican holding, is kept at the INIFAP (Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias, Mexico) Germplasm Bank. After evaluation, the genetic structure of this collection (200 accessions) was compared with that of landraces from
