BAC library; Bubalus bubalis; Cloning; Pulse-field gel electrophoresis

River buffalo genome analyses have advanced significantly in the last decade, and the genome sequence of Bubalus bubalis will be available shortly. Nonetheless, large-insert DNA library resources such as bacterial artificial chromosomes (BAC) are still required for validation and accurate assembly of the genome sequence. We constructed a river buffalo BAC library containing 52, ... more

Bubalus bubalis; GC-rich; Molecular cloning; rDNA; rRNA

The rDNA genes coding for ribosomal RNA in animals are complicated repeat sequences with high GC content. We amplified water buffalo rDNA gene sequences with the long and accurate (LA) PCR method, using LA Taq DNA polymerase and GC buffer, based on bioinformatic analysis of related organisms. The rDNA genes were found to consist of 9016 nucleotides, including three rRNA genes and two ... more

Bubalus bubalis; Genetic correlation; Heritability; Random regression models; Sire rank

The objective of this study was to estimate variance components and genetic parameters for accumulated 305-day milk yield (MY305) over multiple ages, from 24 to 120 months of age, applying random regression (RRM), repeatability (REP) and multi-trait (MT) models. A total of 4472 lactation records from 1882 buffaloes of the Murrah breed were utilized. The contemporary group (herd-year- ... more

Bubalus bubalis; Gibbs analyses; Milk composition

Buffalo milk has excellent physical and chemical qualities as a consequence of the high percentage of constituents. This milk property is desirable for the dairy industry because it facilitates manufacture of mozzarella cheese. We estimated genetic parameters for milk yield, milk fat and protein and their effects on mozzarella cheese production using Bayesian inference. Using information ... more

Bubalus bubalis; Chromosome 1; Comparative map; Radiation hybrid mapping

River buffalo chromosome 1 (BBU1) is a sub-metacentric chromosome homologous to bovine chromosomes 1 and 27. In this study, we constructed a new framework radiation hybrid (RH) map from BBU1 using BBURH5000 panel adding nine new genes (ADRB3, ATP2C1, COPB2, CRYGS, P2RY1, SLC5A3, SLC20A2, SST, and ZDHHC2 ... more

Cross-species; Kelp grouper; Pyrosequencing; Transferability

The kelp or longtooth grouper (Epinephelus bruneus), which inhabits Eastern Asia, is the most economically important of 11 grouper species that inhabit the Southern Sea near Jeju Island in Korea. This species is listed as vulnerable by the International Union for the Conservation of Nature and Natural Resources because of a rapid decrease in its resources. We developed ... more

Cross-species transfer; Microsatellite; Mytilus coruscus; Pyrosequencing

The Korean mussel Mytilus coruscus, an endemic marine bivalve mollusk, is economically important. Its population is currently decreasing due to overexploitation and invasion of a more competitive species, Mytilus galloprovincialis. In this study, microsatellite markers for M. coruscus were developed using a cost-effective pyrosequencing technique. Among the 33, ... more

Currently assembling genomes without reference is one of the most important challenges for bioinformaticists all over the world in an attempt to characterize new organisms. The current study has used two dengue virus type 4 (DENV-4) strains recently isolated in Brazil, which have its genomes sequenced using the GSFLX 454 sequencer (Roche, Life Science) by the pyrosequencing method. The ... more

BAC library; FABP6; Murrah; Next generation sequencing

In this study, we compared the complete sequence of the FABP6 gene from an animal representing the Murrah breed of the river buffalo (Bubalus bubalis) with the gene sequence from different mammals. The buffalo FABP6 gene is 6105 bp in length and is organized into four exons (67, 176, 90, and 54 bp), three introns (1167, 1737, and 2649 bp), a 5ꞌUTR (93 bp), and a ... more

Interferon regulatory factor 1 (IRF1) is functionally diverse in the regulation of immune response and is considered to be an important candidate gene for studying disease susceptibility in mammals. In this paper, we characterized the whole sequence of the IRF1 gene in river buffalo (Bubalus bubalis) and compared genomic and the amino acid sequences between different species. The ... more
