Data from: The MC1R and ASIP coat color loci may impact behavior in the horse
Shared signaling pathways utilized by melanocytes and neurons result in pleiotropic traits of coat color and behavior in many mammalian species. For example, in humans polymorphisms at MC1R cause red hair, increased heat sensitivity, and lower pain tolerance. In deer mice, rats, and foxes, ASIP polymorphisms causing black coat color lead to more docile demeanors and reduced activity. Horse (Equus caballus) base coat color is primarily determined by polymorphisms at the Melanocortin-1 Receptor (MC1R) and Agouti Signaling Protein (ASIP) loci, creating a black, bay, or chestnut coat. Our goal was to investigate correlations between genetic loci for coat color and temperament traits in the horse. We genotyped a total of 215 North American Tennessee Walking Horses for the 2 most common alleles at the MC1R (E/e) and ASIP (A/a) loci using previously published PCR and RFLP methods. The horses had a mean age of 10.5 years and comprised 83 geldings, 25 stallions, and 107 mares. To assess behavior, we adapted a previously published survey for handlers to score horses from 1 to 9 on 20 questions related to specific aspects of temperament. We utilized principle component analysis to combine the individual survey scores into 4 factors of variation in temperament phenotype. A factor component detailing self-reliance correlated with genotypes at the ASIP locus; black mares (aa) were more independent than bay mares (A_) (P = 0.0063). These findings illuminate a promising and novel animal model for future study of neuroendocrine mechanisms in complex behavioral phenotypes.

Data from: Genome-wide association study for tobiano spotting coat color in Korean Jeju × Thoroughbred horse population
Korean Jeju horse features a small to medium frame size and stature having varieties of coat colors including grey, milky, spotted and bay1. Crossbreeding with Thoroughbred has been a long tradition in Korea to have intermediate frame size horse suitable for racing, leisure activities and meat production2. Tobiano white-spotting pattern is preferred by many horse breeders and owners which is inherited as an autosomal dominant trait1,3. Polymorphisms in proto-oncogene receptor tyrosine kinase (KIT) gene were strongly associated with tobiano and sabino coat color pattern in American and European horse breeds3,5. In addition, ECA3 inversion locus near KIT gene also significantly associated with tobiano spotting pattern in horses4,5. Here, we report SNPs and harbored genes associated with tobiano coat color in a crossbred horse population through genome-wide SNP association analysis. In this study, coat color patterns of 142 crossbred horses (Jeju indigenous horse × Thoroughbred) were verified according to previously described methods3,5 and coded as "0" or "1" (Figure S1). Genomic DNA was extracted from blood samples using DNeasy 96 blood DNA extraction Kit (QIAGEN, USA). Genotyping was performed using Equine SNP 50K BeadChip (Illumina, San Diego, USA) at AGBD, NIAS, Korea. A total of 45,204 SNPs passed the set quality control criteria as minor allele frequency (MAF<0.01), missing genotype (GENO>0.10) and Hardy-Weinberg equilibrium (HWE<0.0001) in 142 individuals. Finally, a set of 16,223 independent SNPs were generated through –indep –pairwise 25 5 0.25 pruning6. Genome wide association study revealed 18 Bonferroni adjusted SNPs located on chromosome 3 (ECA3) significantly associated with tobiano coat color in the studied population (Figure 1, Table S1). These SNPs broadly plotted on 40 Mbp region (from 39 to 79 Mbp) of ECA3 which might be due to high LD among the significant SNPs. The most significant association was found between ECA3 inversion locus (77657979 bp) and tobiano pattern (P< 5.56×10-17) while the second highest association was detected with SNP rs68555258 (48853535 bp; P< 4.04×10-12, Table S1). Apart from this, genotypes of ECA3 inversion locus by pyrosequencing matched perfectly in our study (Table S2). All tobiano horses (n = 37) were heterozygous for inversion locus (+/To) while solid-colored horses (n = 103) were homozygous (+/+). ECA3 inversion is located 70 kbp downstream from KIT gene which possessed causal variants for tobiano pattern in horse5,6. The Biomart and Variant Effect Predictor tools in Ensembl Genome Browser (http://www.ensembl.org/index.html) identified several significant SNPs harboring genes of which GPRIN3, ARHGAP24, SCFD2, RASSL11B and WDFY3 are noticeable (Table S3). Based on our genome wide association and inversion locus genotyping results, it is suggested that ECA3 inversion locus variant is either causative or completely linked with causative variants for tobiano coat color in this crossbred horse population. Moreover, a set of putative mutations in other genes might be in high LD with causative variants that could be explored for functional annotations associated with tobiano coat color pattern in horse population.
