Genetic and phenotypic parameters of carcass and organ traits of broiler chickens
Authors: G.C. Venturini1, V.A.R. Cruz1, J.O. Rosa1, F. Baldi1, L. El Faro3, M.C. Ledur2, J.O. Peixoto2 and D.P. Munari1
The objective of this study was to estimate the genetic and environmental parameters for carcass, carcass part, and organ weights in a paternal strain of broiler chickens that was selected mainly for body weight at 42 days of age (BW42) to provide support for poultry genetic improvement programs. A total of 1448 chickens were used that resulted from the e.. Read More»

Influence of aberrant myeloid expression on acute lymphoblastic leukemia in children and adolescents from Maranh�£o, Brazil
Authors: T.C. Lopes1, K.N.S. Andrade1, N.L. Camelo1, V.P. Rodrigues2 and R.A.G. Oliveira3
The aim of this study was to evaluate myeloid expression in acute lymphoblastic leukemia (ALL) in children and adolescents who had been referred to the Oncology Department in a hospital in the State of Maranhão based on demographic, laboratory, and clinical data. Myeloid expression was evaluated in 65 patients under 18 years of age who were diagnos.. Read More»

Comparison of small scale methods for the rapid and efficient extraction of mitochondrial DNA from wheat crop suitable for down stream processes
Authors: M. Ejaz*, Z. Qidi*, Z. Gaisheng, W. Qunzhu, N. Na and Z. Huiyan
We evaluated and compared 2 mitochondrial DNA (mtDNA) extraction methods in terms of DNA quality and success of subsequent polymerase chain reaction (PCR) amplifications from etiolated leaves of wheat crop (Triticum aestivum). mtDNA extraction is difficult because the presence of metabolites interfere with DNA isolation procedures and downstream applicati..

Increasing genetic variability in black oats using gamma irradiation
Authors: G. Silveira1, E. Moliterno2, G. Ribeiro3, P.M.A. Costa1, L.G. Woyann4, E.W. Tessmann4, A.C. Oliveira4 and C.D. Cruz1
The black oat (Avena strigosa Schreb) is commonly used for forage, soil cover, and green manure. Despite its importance, little improvement has been made to this species, leading to high levels of genotypic disuniformity within commercial cultivars. The objective of this study was to evaluate the efficiency of different doses of gamma rays [60Co] applied .. Read More»

DNA barcoding for species identification in the Palmae family
Authors: A. Naeem1, A.A. Khan1, H.M.N. Cheema1, I.A. Khan1 and A. Buerkert2
DNA barcoding is a promising tool for species identification at the molecular level. The barcoding system is well established for species differentiation in animals, while it is less common in plants. We evaluated 2 barcoding regions, maturase K (matK) and ribulose bisphosphate carboxylase (rbcL), to compare species of Palmae according to amplification su.. Read More»

Genetic control of inflorescence in common bean
Authors: S.R. Guilherme1, M.A.P. Ramalho1, A. de F.B. Abreu2 and L.A. Pereira1
The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyze.. Read More»

Polymorphic microsatellite markers for the rare and endangered cactus Uebelmannia pectinifera (Cactaceae) and its congeneric species
Authors: E.M. Moraes1, F.W. Cidade1, G.A.R. Silva1 and M.C. Machado2
The cactus genus Uebelmannia includes 3 narrow endemic species associated with rocky savanna habitats in eastern South America. Because of their rarity and illegal over-collection, all of these species are endangered. Taxonomic uncertainties resulting from dramatic local variation in morphology within Uebelmannia species preclude effective conservation ef.. Read More»

Genetic-molecular characterization of backcross generations for sexual conversion in papaya (Carica papaya L.)
Authors: H.C.C. Ramos1, M.G. Pereira1, T.N.S. Pereira1, G.B.A. Barros1 and G.A. Ferreguetti2
The low number of improved cultivars limits the expansion of the papaya crop, particularly because of the time required for the development of new varieties using classical procedures. Molecular techniques associated with conventional procedures accelerate this process and allow targeted improvements. Thus, we used microsatellite markers to perform geneti.. Read More»
