Authors: P. Saowaphak, M. Duangjinda, S. Plaengkaeo, R. Suwannasing and W. Boonkum
In this study, we estimated the genetic parameters and identified the putative quantitative trait loci (QTL) associated with the length of productive life (LPL), days open (DO), and 305-day milk yield for the first lactation (FM305) of crossbred Holstein dairy cattle. Data comprising 4,739 records collected between 1986 and 20.. Read More»

Comparison of physical and chemical characteristics of collagen from the skin of cod (Gadus macrocephaius)
Authors: Y. Shu, H. Ren, R. Ao, W.C. Qi and Z.S. Zhang
Acid and pepsin-soluble collagen (ASC and PSC, respectively) were extracted from cod (Gadus macrocephaius) skin, and yields of 37.36 and 55.96% were obtained for ASC and PSC, respectively. The total yield of ASC and PSC was 93.92%, based on the lyophilized dry weight, which is higher than that obtained from other sources. Elec.. Read More»

Phenotypic and genotypic characterization of Staphylococcus aureus isolates in milk from flocks diagnosed with subclinical mastitis
Authors: A.R.E.O. Xavier, A.C. Almeida, C.N. Souza, L.M.V Silva, A.X.A. Ruas, D.A. Sanglard, A.F.M. J�ºnior , A.M.E. Oliveira and M.A.S. Xavier
The Staphylococcus aureus is the most common isolated microorganism in ruminant animal species diagnostic with clinical or subclinical mastitis. Dairy herds with these diseases can transfer S. aureus into the milk supply, which can lead to food poisoning in humans. The objective of this study was to evaluate the profile of ant.. Read More»

Transferability of microsatellite markers in Syagrus coronata (Mart.) Becc. (Arecaceae), an iconic palm tree from the Brazilian semiarid region
Authors: R.R. Simplicio, D.G. Pereira and A.M. Waldschmidt
The licuri palm Syagrus coronata plays a key role in the ecology and economy of Brazilian semiarid region. Nonetheless, genetic data about populations of this species are absent even though the intensive and uncontrolled exploitation since colonial periods has threatened the sustainability and viability of licuri populations. ..

Selection of candidate reference genes and validation for real-time PCR studies in rice plants exposed to low temperatures
Authors: P.A. Auler, L.C. Benitez, M.N. do Amaral, I.L. Vighi, G.S. Rodrigues, L.C. da Maia and E.J.B. Braga
Rice is a cereal that presents a great ability to adapt to different soil and climate conditions. However, as it is a tropical crop with C3 metabolism, it performs better in warm temperatures with high solar radiation. Tolerance to stress caused by low temperatures is a highly complex process that involves various metabolic pa.. Read More»

Haplotypes and polymorphism in the CCR5 gene in sickle cell disease
Authors: A.F. Nascimento, J.S. Oliveira, J.C. Silva Junior and A.A.L. Barbosa
Sickle cell disease shows several clinical manifestations in distinct levels of severity. This heterogeneity is due to the haplotype variability associated with the HbS gene, levels of fetal hemoglobin and environmental conditions, which modify the disease expression. Science community believes that the presence of a polymorph.. Read More»

Genome-wide analysis of salinity-stress induced DNA methylation alterations in cotton (Gossypium hirsutum L.) using the Me-DIP sequencing technology
Authors: X.K. Lu, N. Shu, J.J. Wang, X.G. Chen, D.L. Wang, S. Wang, W.L. Fan, X.N. Guo, L.X. Guo and W.W. Ye
Cytosine DNA methylation is a significant form of DNA modification closely associated with gene expression in eukaryotes, fungi, animals, and plants. Although the reference genomes of cotton (Gossypium hirsutum L.) have been publically available, the salinity-stress-induced DNA methylome alterations in cotton are not well unde.. Read More»

Maize hybrid stability in environments under water restriction using mixed models and factor analysis
Authors: A.O. Santos, J.J. Nuvunga, C.P. Silva, L.P.M. Pires, R.G. Von Pinho, L.J.M. Guimar�£es and M. Balestre
In several crops, the water deficit is perhaps the main limiting factor in the search for high yields. The objective of this study was to evaluate the phenotypic stability of maize hybrids in environments with and without water restriction using the analytical factor (AF) approach. We evaluated 171 maize hybrids in 14 environm.. Read More»

Implications of the clone by harvest interaction in the selection of sugarcane genotypes in a regionalized program
Authors: D.N.A. Cabral, J.A.R. Nunes, P.D.S. Cabral, J. Zuchi, A.J. Raizer and T.O.M. De Paula
The recommendation of sugarcane clones depends on several factors, as the response or performance of the clones over different cuts or harvests. The clone by harvest interaction might be difficult to identify superior clones in the final stages of the sugarcane breeding program. Thus, the objective of this study was to investi.. Read More»

Gas exchanges and water use efficiency in the selection of tomato geno-types tolerant to water stress.
Authors: M.E.A. Borba, G.M. Maciel, E.F. Fraga Junior, C.S. Machado Junior,G.R. Marquez, I.G. Silva and R.S. Almeida
Water stress can affect the yield in tomato crops and, despite this, there are few types of research aiming to select tomato genotypes resistant to the water stress using physiological parameters. This experiment aimed to study the variables that are related to the gas exchanges and the efficiency in water use, in the selectio.. Read More»
