1. Genetic variability of Brazilian rice landraces determined by SSR markers.
Abstract ? The objective of this study was to evaluate the genetic variability of rice (Oryza sativa) landraces collected in Brazilian small farms. Twelve simple sequence repeat (SSR) markers characterized 417 landraces collected in 1986, 1987 and 2003, in the state of Goiás, Brazil. The number of landraces with long and thin grain type increased in the eva

2. Variabilidade genética em acessos de caupi analisada por meio de marcadores RAPD.
O conhecimento da variabilidade genética e da relação entre diferentes acessos de caupi é importante para maximizar o uso dos recursos genéticos disponíveis. Esse trabalho teve como objetivo avaliar a variabilidade genética em 45 acessos de caupi (Vigna unguiculata (L.) Walp.) oriundos do Brasil, EUA e Nigéria, por meio de marcadores RAPD. Foram enco

3. Perfil transcricional durante o desenvolvimento muscular esquelético de suínos de uma raça local Brasileira e dois grupos genéticos comerciais / Transcriptional profiling during pig skeletal muscle development of a Brazilian local breed and two commercial genetic groups
O desenvolvimento esquelético muscular é um processo complexo que envolve a expressão coordenada de milhares de genes. O objetivo deste estudo foi identificar genes diferencialmente expressos no músculo longissimus dorsi (LD) de suínos, bem como seus padrões de expressão entre cinco estádios do desenvolvimento. Primeiramente, uma análise de microarr

4. Estudos de locos de características quantitativas, de expressão gênica e teste de paternidade em suínos / Studies of quantitative trait loci, genic expression and of paternity testing in pigs
The accomplishment of the present study had as objective: 1) to map Quantitative Trait Loci (QTL) on chromosomes 1, 2, 3, 12, 14, 15 and X in a F2 pig population developed by mating two Brazilian Piau breed sires with 18 dams from a commercial line (Landrace × Large White × Pietrain); 2) investigate the level of expression of candidate genes influencing ec

5. Quantitative trait loci for carcass, internal organ and meat quality traits on porcine chromosomes 16, 17 and 18
The objective of this study was to map quantitative trait loci (QTL) on porcine chromosomes 16, 17 and 18 and to determine their association with carcass, organ and meat quality traits. An F2 population was produced by crossing two boars of the naturalized Brazilian Piau breed with 18 commercial females (Landrace x Large White x Pietrain). The population was

6. Association of the estrogen receptor gene Pvu II restriction polymorphism with expected progeny differences for reproductive and performance traits in swine herds in Brazil
Estrogen has an important function in swine reproduction and growth. A Pvu II restriction enzyme polymorphism has been proven to be an important genetic variation in the estrogen receptor gene (ESR) and may be considered as a candidate gene for use in pig production but there is no data regarding the prevalence of this polymorphism in the Brazilian pig popul

7. Níveis de expressão dos genes FABP3 e FABP4 e conteúdo de gordura intramuscular em suínos / Expression levels of the FABP3 and FABP4 genes and intramuscular fat content in pigs
Genes FABP3 (heart fatty acid-binding protein gene) and FABP4 (adipocyte fatty acid-binding protein gene) have been indicated as candidate genes to the intramuscular fat deposition in pigs. The present research aimed to analyze the levels of expression of these genes in the Longissimus dorsi (LD) and Semimembranosus (SM) muscles of commercial (Landrace X Lar

8. Nutritional Value of Swine Feeds Determined at the Federal University of Lavras / Valor nutricional de alimentos para suÃnos determinado na Universidade Federal de Lavras
The present work was conducted in order to evaluate the chemical and nutritional composition of 35 protein feeds and 67 energy feeds through the compilation of data from the research works of metabolism trials on swine performed at the Animal Science Department of the UFLA in the period from 1996 to 2002. It was utilized the protein feeds such as of cottonse
