A gene-transcription factor network associated with residual feed intake based on SNVs/InDels identified in Gir, Girolando and Holstein cattle breeds. Repositório Alice
VERARDO, L. L.; STAFUZZA, N. B.; MUNARI, D. P.; ZERLOTINI NETO, A.; CHUD, T. C. S.; GARRICK, D. J.; COLE, J. B.; PANETTO, J. C. do C.; MACHADO, M. A.; MARTINS, M. F.; SILVA, M. V. G. B..
The aim of this study was to analyze whole-genome re-sequencing data focusing on SNVs and InDels identified in Gir, Girolando and Holstein cattle breeds related to RFI. Thus, genes showing SNVs/InDels in TF binding sites (5' UTR variants) were used to search for TF related to feed intake and to generate a gene-TF network for RFI across two purebred and one admixed dairy cattle breeds. Moreover, we were able to perform a comparative analysis accessing similarities and dissimilarities at the genomic level across these breeds.

BUZANSKAS, M. E.; GROSSI, D. do A.; VENTURA, R. V.; SCHENKEL, F. S.; CHUD, T. C. S.; STAFUZZA, N. B.; ROLA, L. D.; MEIRELLES, S. L. C.; MOKRY, F. B.; MUDADU, M. de A.; HIGA, R. H.; SILVA, M. V. G. B.; ALENCAR, M. M. de; REGITANO, L. C. de A.; MUNARI, D. P..
Background: Beef cattle breeding programs in Brazil have placed greater emphasis on the genomic study of reproductive traits of males and females due to their economic importance. In this study, genome-wide associations were assessed for scrotal circumference at 210 d of age, scrotal circumference at 420 d of age, age at first calving, and age at second calving, in Canchim beef cattle. Data quality control was conducted resulting in 672,778 SNPs and 392 animals. Results: Associated SNPs were observed for scrotal circumference at 420 d of age (435 SNPs), followed by scrotal circumference at 210 d of age (12 SNPs), age at first calving (six SNPs), and age at second calving (four SNPs). We investigated whether significant SNPs were within genic or surrounding...

Copy number variation in dairy cattle using next-generation sequencing. Repositório Alice
CHUD, T. C. S.; BICKHART, D. M.; ZERLOTINI NETO, A.; COLE, J. B.; SILVA, M. V. G. B.; MUNARI, D. P..
Gene copy number variants (CNV) have been shown to be associated with several production traits in dairy cattle; however, the detection and validation of CNVs in crossbred cattle is currently lacking. In order to provide a basis for future association studies, we sought to identify CNV regions (CNVRs) within the Girolando composite breed resulting from a mating of the Holstein (taurine) and Gir (indicine) breeds. A read depth method was performed using CNVnator software on NGS data from two Girolando, two Gir and ten Holstein bulls. The individual CNVs were merged into CNVRs based on genomic regions overlapping by at least 1 bp. In total, we identified a composite of 1,286 CNVRs (520 deletions, 255 duplications, 511 mixed) on the genomes of all samples. We...

Detection of potential genetic variants affecting gene function in Guzerat cattle. Repositório Alice
ZERLOTINI NETO, A.; STAFUZZA, N. B.; LOBO, F. P.; YAMAGISHI, M. E. B.; CHUD, T. C. S.; CAETANO, A. R.; MUNARI, D. P.; GARRICK, D. J.; MACHADO, M. A.; MARTINS, M. F.; CARVALHO, M. R.; SILVA, M. V. G. B..
Guzerat is a dual-purpose breed recognized for important traits to its adaptation to adverse tropical environments such as resistance to parasites, heat tolerance and ability to intake forage with low nutritional value. Once genetic variation responsible for this traits has so far not been well characterized, the aim of this study was to identity single nucleotide variants (SNVs) and insertion/deletions (Indels) in Guzerat cattle breed from whole genome re-sequencing in order to characterize loss-of-function variants which could be associated with complex traits in this cattle breed.

Estratégias de imputação em gado Canchim utilizando população de referência da raça Nelore. Repositório Alice
MARCIANO, L. E. A.; MAIA, R. de O. G.; SANTOS; DUARTE, I. N. H.; BERNARDES, P. A.; CHUD, T. C. S.; REGITANO, L. C. de A.; BUZANSKAS, M. E..
The use of genomic tools in animal breeding has been widely applied to improve productivity. Imputation methods could be used to reduce genotyping costs and increase the amount of genomic information, which are needed for various studies. The aim of this study was to consider the Canchim cattle (a composite beef breed) as target population and the Nelore breed as reference population to evaluate the imputation accuracy. A total of 285 Canchim, 114 MA genetic group and 814 Nelore animals were used in this study. Imputation was carried out using the FImpute software and genotype imputation accuracy was measured by concordance rate (CR) and allelic R square (R2). Five imputation scenarios were tested and CR results varied from 64.71% to 89.69%. The R2 varied...

Genetic parameters and mapping quantitative trait loci associated with tibia traits in broilers. Repositório Alice

Abstract: Selection among broilers for performance traits is resulting in locomotion problems and bone disorders, once skeletal structure is not strong enough to support body weight in broilers with high growth rates. In this study, genetic parameters were estimated for body weight at 42 days of age (BW42), and tibia traits (length, width, and weight) in a population of broiler chickens. Quantitative trait loci (QTL) were identified for tibia traits to expand our knowledge of the genetic architecture of the broiler population. Genetic correlations ranged from 0.56 +/- 0.18 (between tibia length and BW42) to 0.89 +/- 0.06 (between tibia width and weight), suggesting that these traits are either controlled by pleiotropic genes or by genes that are in linkage...

Genome-wide association study on long-yearling scrotal circumference in Canchim cattle. Repositório Alice

Genome-wide association studies provide valuable information for understanding the genetic control of complex traits in livestock. The goal of this study was to investigate the association of the BovineHD BeadChip SNP genotypes with estimated breeding values for long-yearling scrotal circumference adjusted to 420 days (SC420) in Canchim beef cattle. A total 435 SNPs were significantly associated with SC420 (10% chromosome-wise FDR), of which 30 were located in genes on chromosomes 5, 13, and 14, including HEY1, PLCG1, PAG1, ZFHX4, PEX2, FABP5, FABP12, MED30, and TRHR genes. These genes play a role in biological processes related to reproduction, fat deposition, and hormonal systems development. Future studies targeting these regions and genes could provide...

Selection signature (SS) was assessed in this study by means of the integrated haplotype score (iHS) method, which determines the decay of homozygosity in the surroundings of a core single nucleotide polymorphism (SNP) marker. Canchim breed animals were genotyped using the Illumina BovineHD BeadChip; which has almost 800 thousand SNP markers. Genotype quality control (QC) was applied to exclude SNP with genotype calling score lower than 0.20; SNP with minor allele frequency lower than 0.01; and call rate for SNP and samples which were lower than 0.95 and 0.90, respectively. Only autosomal SNPs with known genome position were used. After the QC, 687,655 SNPs and 396 samples remained for SS analysis. Signals of SS were detected on chromosomes 5, 6, 8, and...

Background: Recent technological advances in genomics have allowed the genotyping of cattle through single nucleotide polymorphism (SNP) panels. High-density SNP panels possess greater genome coverage and are useful for the identification of conserved regions of the genome due to selection, known as selection signatures (SS). The SS are detectable by different methods, such as the extended haplotype homozygosity (EHH); and the integrated haplotype score (iHS), which is derived from the EHH. The aim of this study was to identify SS regions in Canchim cattle (composite breed), genotyped with high-density SNP panel. Results: A total of 687,655 SNP markers and 396 samples remained for SS analysis after the genotype quality control. The iHS statistic for each...

Whole-genome re-sequencing, alignment and annotation analyses were undertaken for 12 sires representing four important cattle breeds in Brazil: Guzerat (multi-purpose), Gyr, Girolando and Holstein (dairy production). A total of approximately 4.3 billion reads from an Illumina HiSeq 2000 sequencer generated for each animal 10.7 to 16.4-fold genome coverage. A total of 27,441,279 single nucleotide variations (SNVs) and 3,828,041 insertions/ deletions (InDels) were detected in the samples, of which 2,557,670 SNVs and 883,219 InDels were novel. The submission of these genetic variants to the dbSNP database significantly increased the number of known variants, particularly for the indicine genome. The concordance rate between genotypes obtained using the Bovine...
