Single Nucleotide Variations in the Buffalo Kappa-Casein Gene (CSN3)

Caseins are the major milk proteins associated with lactation performance, milk composition and cheese yield efficiency, representing around 80% of the total amount of proteins found in milk. Among the caseins, kappa-casein is the protein that stabilizes micelle structure during milk coagulation process and being used during the cheese production. The kappa-casein gene (CSN3) has been previously mapped to buffalo chromosome 7 using a radiation hybrid panel and a comparative map was established using the sequence from bovine chromosome 6. The molecular structure of this gene has also been established in river buffalo, with a total length of 13,191 bp (GenBank: AM900443.1) and containing five exons. In this study we searched for single nucleotide variations in specific regions of the CSN3 gene in three animals representing the Murrah breed. Sequencing reactions were performed using ABI3730xl sequencer. The primer walking method was used to span the 5'-UTR and intron 2 regions of the gene, for which ten primer pairs were designed using Oligo 6 software. BLAST tool was used to verify the primers specificity. DNA sequences assemblies from all three animals were performed with Sequencher (R) software 4.1, while multiple alignments were performed using Clustal W software to identify single nucleotide variations. The sequencing revealed a total of 19 single nucleotide variations with 13 located in the upstream regulatory region of the gene (5'-UTR) and six on intron 2. These variations can be validated using commercial populations segregating specific economic traits.

Estudo do reservatório de coquinas do grupo Lagoa Feia (Eocretáceo) na acumulação de Linguado, sudoeste da Bacia de Campos

The Linguado Field is located in the extreme southwest portion of Campos Basin. It’s associated with Structural Badejo High and can be divided in two groups of faults: one manly formed by antithetic faults, with NW-SE direction, continuous to Badejo Fault, and another identified by N-S faults. Besides these faults had affected the basement and the stratification of basin, these systems also had contributed to coquina permoporosity development, that show 80% of recoverable oil volume of the field. The carbonate marine sequence, Albian age, it was deposited under the salt. This forms structures as like as pillows and raft as a result of the halocinese. Structurally the Linguado Field coquina has monoclinal direction with east dip, it’s cut by faults with slip up to 50 meters. In addition to structural control, stratigraphy and diagenesis also were important to carbonate trap oil. The identification of recoverable oil levels in the low phase of the coquina from Lagoa Feia Group was done by well data. The seismic 2D and 3D, with the well data, was used to structural interpretation to regional scale either to reservoir scale.
