Genomic structural variation, in the form of large-scale insertions and deletions, as well as inversions and translocations, are referred to as copy number variations (CNVs). Compared to single nucleotide polymorphisms (SNPs), CNVs have potentially greater effects on gene structure, dosage and regulation, being an important source of phenotypic variation. In humans, CNVs are widespread in the genome and have been shown to be associated with complex traits. In livestock species, the characterization of this genetic variation is an important step toward linking genes or genomic regions with phenotypic traits of economic importance. Studies in cattle have revealed some CNVs associated with differences in host parasite resistance and breed-specific differences in adaptation, health, and production traits. We report initial data from an analysis of CNVs in Canchim, a synthetic cattle (5/8 Charolais + 3/8 Zebu) that has been selected for meat production in Brazil. Using the PennCNV software and data from 192 Canchim DNA samples with extreme phenotypes for ribeye area, genotyped with Illumina BovineHD BeadChip, a total of 6,985 CNVs were detected. The regions ranged from 20,012bp to 4,157,122bp, with mean and median of 140,484bp and 81,303bp, respectively. Copy number gains (62.09%) were found to be more common than deletions. Gene content of discovered CNVs and functional enrichment analysis are being assessed using Ensembl genes and cattle RefSeq databases, and PANTHER classification system, respectively. We expect to use these findings in genome wide association studies to better understand the genetic variation underlying meat quality in beef cattle.

Ferralsols are characterized by poorly-defined horizons, weak macrostructure and strong development of a fine granular structure comprising subangular micro-aggregates. In this study, the morphological and physical modifications caused by earthworm activity in a clayey ferralsol were analysed. After describing soil structures, undisturbed samples were taken for evaluating aggregates and determining clod bulk density and particle density. Soil water retention properties were measured and an inventory of soil invertebrate macrofauna was created. The structural and porous transformations were due to aggregates created by earthworm activity. Changes in bulk density can be associated with pore modifications caused by a change in the proportions of aggregate types, and a notable reduction of total porosity was measured, tending to increase soil volume with dense aggregates. Structural modifications affected the topsoil down to 0.5 m and water retention between 1 and 33 kPa, the principal water compartment of these soils. |
