DNA testing for parentage verification in a conservation nucleus of Pantaneiro horse Genet. Mol. Biol.
Sereno,Fabiana Tavares Pires de Souza; Sereno,José Robson Bezerra; Vega-Pla,Jose Luis; Delgado,Juan Vicente.
We investigated the genealogy of the in situ conservation nucleus of the Pantaneiro horse using DNA microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). Genomic DNA was extracted from hair roots and genotyped using 12 microsatellite markers (AHT4, AHT5, ASB2, ASB17, ASB23, HMS3 HMS6, HMS7, HTG4, HTG10, LEX33 and VHL20). The number of alleles per locus varied from 6 to 13, with a mean of 7.8 and the expected heterozygosity ranged from 0.544 to 0.734 (mean 0.644). The VLH20, ASB2, HTG10, ASB23 markers had a high (> 0.8) polymorphism information content and the total exclusion probability of the 12 microsatellite loci was 0.99. The genealogical study of...

Effects of inclustion and exposition times of sugar cane to calcium oxide on the physiologic and digestive parameters of Nellore heifers R. Bras. Zootec.
Pina,Douglas dos Santos; Valadares Filho,Sebastião de Campos; Azevêdo,José Augusto Gomes; Barbosa,Analívia Martins; Valadares,Rilene Ferreira Diniz; Detmann,Edenio.
It was aimed to evaluate the effect of inclusion and times of sugar cane exposition to whitewash on intake and total and partial digestibility of nutrients and ruminal parameters and to compare titanium dioxide and chromium oxide as markers to estimate fecal dry matter excretion and dry matter abomasal flow. It was used six rumen and abomasum cannulated Nellore females, with average body weight of 250 ± 19 kg, distributed in an incomplete 6 x 6 latin square design. The experiment was set in a 3 x 2 factorial scheme with three levels of whitewash (0; 0.5 or 1.0% natural matter) and two times of sugar cane storage (0 and 3 days). There was no effect of storage times neither interaction among levels of whitewash and storage times on the intake of nutrients....

Estimating the effects of population size and type on the accuracy of genetic maps Genet. Mol. Biol.
Ferreira,Adésio; Silva,Marcia Flores da; Silva,Luciano da Costa e; Cruz,Cosme Damião.
Based on simulation studies, it was shown that the type and size of experimental populations can exert an influence on the accuracy of genetic maps. A hypothetical genome map (one chromosome with nine equidistant molecular markers) was generated for the following population types: F2 with dominant and co-dominant markers, backcrossing, recombinant inbred lines (RIL) and double-haploid. The population sizes were 50, 100, 150, 200, 500 and 1000 individuals and 100 simulations were made for each population. The inaccuracies of the populations with the lowest number of individuals were shown by inversions in the order of the markers and the establishment of more than one linkage group in up to 38% of the simulations, depending on the population type. Stress...

Genetic diversity of the common bean Phaseolus vulgaris L. determined by DNA-based molecular markers. Repositório Alice
VASCONCELOS, M. J. V.; BARROS, E.G.de; MOREIRA, M.A.; VIEIRA, C..
Weselected 28 potential common bean (Phaseolus vulgaris L.) progenitors to determine their genetic diversity using RAPD technique. They were divided into two groups based on their type of storage protein (phaseolin); 18 of them had type "S" phaseolin and the other 10 had phaseolin. DNA samples of all the cultivars were amplified in vitro with oligonucleotide primiers of random sequences. A total of 276 amplification products, 144 of them being polymorphic, were obtained with 45 different primers. Multivariate analysis of these data divided the cultivars into groups and, in addition, allowed a more precise intra and intergroup distinction.

N-alkanes to estimate voluntary forage intake of cattle using controlled-release capsules Scientia Agricola
Oliveira,Dimas Estrasulas de; Manella,Marcelo de Queiroz; Tedeschi,Luis Orlindo; Silva,Sila Carneiro da; Lanna,Dante Pazzanese Duarte.
N-alkanes have been used as internal markers in digestibility trials with ruminants and non-ruminants for more than 20 years. In this study, two trials were conducted under different feeding regimes to (i) evaluate the release rate of n-alkanes of controlled-release capsules in the rumen of rumen-cannulated steers either grazing or restrained in metabolic stalls and (ii) estimate voluntary forage intake of the same steers in metabolic stalls. Six rumen-cannulated Nelore steers were allocated to individual metabolic stalls and were fed diets with varying forage to concentrate ratios (80:20, 60:40, and 40:60; respectively). Corn silage was the only forage source. In the grazing trial, the same steers were evaluated under three feeding managements (Brachiaria...

Perspectives on the application of biotechnology to assist the genetic enhancement of plantain and banana (Musa spp.) Electron. J. Biotechnol.
Crouch,Jonathan H.; Vuylsteke,Dirk; Ortiz,Rodomiro.
Bananas and plantains (Musa spp.) are the most important tropical fruit crops. They form an integral component of the farming systems in the humid agroecological zones of the tropics. A broad array of applied cell and molecular techniques are increasingly being used worldwide to facilitate and enhance the handling and improvement of plantain and banana germplasm. Tissue culture is used for germplasm exchange, conservation and rapid multiplication, while in vitro seed germination (based on embryo culture or rescue) plays a critical role in generating hybrid plants. DNA marker systems have been developed in Musa to assist germplasm management, selection within the breeding pool or gene introgression from wild species, and for disease diagnosis. Likewise,...
