Development of a SNP linkage map and genome-wide association study for resistance to Aeromonas hydrophila in pacu (Piaractus mesopotamicus)

This study aimed to investigate the genetic architecture of resistance to A.hydrophila in pacu via a Genome-Wide Association Study (GWAS) to identifyQuantitative Trait Loci (QTLs) and putative genes associated with this trait in 14 pacufull-sib families. An experimental challenge was performed in order to assess the levelsof genetic variation for resistance against the bacteria using the following traitdefinition: binary test survival (TS) and time of death (TD).
