Xiphophorus Genetic Stock Center
Each of the Xiphophorus genomes have been greatly enhanced by PacBio sequencing and Bionano mapping. To take advantage of the improved genomes, the XGSC configured a platyfish genome hub that is hosted on the UCSC genome browser for genetic data visualization and data mining. See link for details.
The XGSC also configured a gene expression browser link to facilitate data visualization and tracking of genes of interest to determine gene basal expression level through light and dark phases over a 24-hr period.
WELCOME TO THE XIPHOPHORUS GENETIC STOCK CENTER
Dedicated to the Poeciliid fish genus Xiphophorus.
Xiphophorus is a freshwater fish genus comprised of 26 species. These fishes live in drainages in eastern Mexico, Guatemala, Belize and Honduras, with most of the described species living in Mexico. The taxa make up three groups: the Northern Swordtails, the Southern Swordtails, and the Platyfish.
The purpose of this site is to provide information to both the research community and the general public about the Xiphophorus Genetic Stock Center. As a national resource for research animals, we welcome opportunities to share fish with the research community for further research, development, and application.
