| The geographical structure of 15 natural populations of the flat oyster (Ostrea edulis L.) was assessed by single-strand conformation polymorphism (SSCP) of a 313-base-pair (bp) fragment of the mitochondrial 12S-rRNA gene. Fourteen haplotypes were observed, with one being dominant in the Mediterranean samples and another one in the Atlantic populations. The geographically extreme populations sampled in Norway and the Black Sea appeared differentiated by exhibiting the dominance of a third group of haplotypes. The results were compared to available microsatellite data at five loci. The Atlantic/Mediterranean differentiation pattern was qualitatively the same with both types of markers, confirming an isolation-by-distance pattern. The average mitochondrial... |

| Since red alleles (R) of the genes that control grain colour are important for the improvement of preharvest sprouting resistance in wheat and there are three independently inherited loci, on chromosomes 3A, 3B and 3D of hexaploid wheat, it is possible to vary the dosage of dominant alleles in a breeding program. The objective of this work was to evaluate the dosage effect of R genes on preharvest sprouting, in a single seed descent population, named TRL, derived from the cross between Timgalen, white-grained wheat, and RL 4137, red-grained wheat. The study was carried out using sprouting data in ripe ears obtained under artificial conditions in a rainfall simulator over three years. According to the results there is a significant effect on preharvest... |

| The transcription factor 7-like 2 gene (TCF7L2) rs7903146 T allele is constantly associated with Type 2 diabetes in various populations and ethnic groups. Nevertheless, this has not been observed in two studies involving Arab populations. The aim of the present study was to investigate the association between TCF7L2 rs7903146 in an Iranian population. Type 2 diabetes patients (N = 258) and normal healthy control subjects (N = 168) from the same area, were examined. The ARMS-PCR (Amplification Refractory Mutation System) technique, subsequently validated by direct sequencing, was used for genotyping. Allele and genotype frequencies were significantly different between patients and controls TT vs. CT + CC [p 0.0081 OR 3.4 95%CI (1.27-11.9)] and T vs. C... |

| Nucleases com efetores do tipo ativador transcricional (do inglês “transcription activator-like effector nucleases” – TALENs) é uma das técnicas incluídas nas chamadas Novas Tecnologias no Melhoramento de Plantas (do inglês “New Plant Breeding Techniques – NPBT”), as quais abrangem um conjunto de novas metodologias e abordagens que diferem da estratégia de melhoramento genético utilizando as técnicas de transgenia clássica que foram desenvolvidas na década de 1990. A tecnologia TALENs apoia-se em novos conhecimentos sobre os processos celulares de expressão e regulação gênica e tanto podem se apresentar como um refinamento das técnicas de modificação por transgenia clássica quanto podem, sob alguns aspectos, produzir eventos de transformação genética... |

| Summer mortality associated with juveniles of the oyster Crassostrea gigas is the result of a complex interaction between the host, pathogens and environment. Divergent selection based on summer survival have been applied to produce families with resistant and susceptible progeny. Here, we describe the use of suppression subtractive hybridization to generate 150 clones that were differentially regulated between resistant and susceptible F2 progeny. The nucleotide sequence of these 150 clones was determined. Among the 25 unique sequences that matched with the products of known genes, those putatively implicated in energy generation (12%) and immune function (16%), systems suspected to be implicated in summer mortality, were extended and analyzed by real... |

| No âmbito da genômica funcional, o estudo do transcriptoma pode auxiliar na elucidação das funções dos genes. Isto é possível devido ao conhecimento existente sobre expressão gênica de que ela ocorre de maneira diferenciada nos diferentes tecidos, nas diferentes fases fenológicas, em geral, nas diferentes situações em que o organismo se encontra. Entretanto, o grande volume de dados gerados pelo NGS requer as ferramentas computacionais para serem analisados. Nesse sentido, um dos objetivos desta publicação é demonstrar a utilização de dois programas de bioinformática que são amplamente utilizados na análise de transcriptoma: Tophat e Cufflinks. |

| The sixty-two of the exotic germplasms waxy corn were performed. The agronomic characters were averaged 45 - 52 days to flowerings, opaque and small kernel. Almost all plant aspects were green and less uniformity, unfortunately, downy mildew was susceptible. Three methods for S1 selection were (1) half - sib (HS) (2) full - sib (FS) and (3) S1 (S1) progeny test. Each method was received for two ears. Also, the agronomic characters were recorded, 45 - 52 days to tasseling and 46 - 52 days to silking. Economic yields, green and white weight were 588 - 1,063 and 340 - 631 kg/rai, namely, UPDW-0013 was showed the best of both. Furthermore, UPCW-0004 showed that the best shelling (71.16%). And, cutting trait was UPWC-0002 (66.67%). Afterward, 26 lines are... |
