Article Synopsis
  • * Analysis of blood pressure and plasma EDN3 levels in Coldblooded trotters and Standardbreds revealed that horses with a sub-elite haplotype had significantly higher blood pressure during exercise compared to those with an elite haplotype.
  • * The findings shed light on the genetic factors influencing athletic performance and vascular traits, suggesting that certain elite haplotypes were present in pre-domestication horses but became more common through selective breeding in modern horses.

Article Synopsis
  • Gene expression differences can help identify genetic mechanisms linked to phenotypic traits, but dense tissues can dilute signals from rare cell types.
  • A study using polyA-selected RNA-seq was conducted on hair and skin samples from domestic horses to compare gene abundance and identify cell-type populations.
  • Results showed that non-invasive hair plucking enriched for specific keratin-related genes, while skin biopsies revealed different populations, suggesting that hair plucking could be a viable alternative to biopsies in certain research contexts.

Article Synopsis
  • The study investigates the genetic factors influencing the conformation of the back and croup in Icelandic horses, which are important for their locomotion and riding performance.
  • Using a genome-wide association analysis on 177 horses, researchers identified a significant genomic region on Equus caballus chromosome 22 linked to back and croup scores.
  • Horses with a favorable genetic haplotype had better conformation and higher scores in specific gaits, indicating potential genetic influences on equine performance.
