25. Species boundary and extensive hybridization and introgression in Petunia
ABSTRACT Studying the role of hybridization in the speciation of plants is one of the most thrilling areas of evolutionary biology. Hybridization in natural populations can act in opposition to divergence, contribute to adaptation through introgression or foster the emergence of new lineages via hybrid speciation. Species of the plant genus Petunia grow in o

27. Liaisons dangereuses: cross-border gene flow and dispersal of insecticide resistance-associated genes in the mosquito Aedes aegypti from Brazil and French Guiana
BACKGROUND In recent years, South America has suffered the burden of continuous high impact outbreaks of dengue, chikungunya and Zika. Aedes aegypti is the main mosquito vector of these arboviruses and its control is the only solution to reduce transmission. OBJECTIVES In order to improve vector control it is essential to study mosquito population geneti

28. Usefulness of 3’- 5’ IS6110-RFLP genotyping and spoligotyping of Mycobacterium tuberculosis isolated in a tertiary hospital: a retrospective study detecting unsuspected epidemiological events
ABSTRACT A drug resistance survey involving Mycobacterium tuberculosis isolated from patients of a tertiary Hospital in the Rio de Janeiro city (RJ), Brazil, between the years 1996 and 1998 revealed a high frequency of isoniazid (HR) resistance. These isolates were revisited and genotyped. Patients came from different RJ neighborhoods and municipalities, and

29. Association mapping of drought tolerance indices in wheat: QTL-rich regions on chromosome 4A
ABSTRACT Drought is likely the main abiotic stress that affects wheat yield. The identification of drought-tolerant genotypes represents an effective way of dealing with the continuous decrease in water resources as well as the increase in world population. The aim of this study was to identify single nucleotide polymorphisms (SNP) associated with drought to

30. Can the genetic polymorphisms of the folate metabolism have an influence in the polycystic ovary syndrome?
ABSTRACT Objective To investigate the association of the genetic variants of the folate metabolism genes (MTHFR C677T; MTHFR A1298C; MTR A2756G; MTRR A66G and RFC-1 A80G) with the development of polycystic ovary syndrome (PCOS). Subjects and methods This study included 203 women (99 women with PCOS and 104 controls). The genotyping was performed by PCR-R

31. A new, harmless, high-throughput endosperm-based DNA extraction method for wheat
RESUMO: Neste estudo, foi desenvolvido um método de extração de DNA não destrutivo, de alto débito e endosperma. Para verificar a natureza não destrutiva deste método, um teste de germinação foi realizado em 288 sementes após a amostragem do endosperma, o que deu uma taxa de emergência de plântulas maior (97,6%) do que a do grupo controle (92%).

34. Effects of melanocortin 1 receptor (MC1R) gene polymorphisms on plumage color in mule ducks
ABSTRACT The objective of the present study was to investigate the effect of single nucleotide polymorphism (SNP) of the melanocortin 1 receptor (MC1R) gene on plumage coloration in mule ducks. PCR-high-resolution melting analysis (PCR-HRM) and DNA sequencing were used to identify the SNP variability of the MC1R gene in white common ducks. Three non-synonymo

35. Detection of virulence genes in Salmonella Heidelberg isolated from chicken carcasses
ABSTRACT During the last years, Brazilian government control programs have detected an increase of Salmonella Heidelberg in poultry slaughterhouses a condition that poses a threat to human health However, the reasons remain unclear. Differences in genetic virulence profiles may be a possible justification. In addition, effective control of Salmonella is rela

36. Stress-induced hashitoxicosis: case report and relative HLA serotype and genotype
RESUMO OBJETIVO Mesmo que o estresse seja conhecido há muito tempo como um fator provocativo para a doença de Graves, sua relação com a tireoidite de Hashimoto é mais controversa. Estudos sobre esse tema são escassos. O objetivo deste artigo é relatar um caso de Hashitoxicose induzida por estresse. RESULTADOS Aqui nós relatamos um caso de Hashitoxi
