The Plant Orthology Browser (POB) is currently being developed as part of the Canadian Wheat Improvement Flagship which represents the National Research Council's contribution to the Canadian Wheat Alliance (CWA), a strategic collaboration with Agriculture and Agri-Food Canada (AAFC), the University of Saskatchewan's Crop Development Centre and the province of Saskatchewan.

Aiming for accelerating variety development of wheat through Genomics Assisted Breeding, POB uses comparative genomics to aid with the identification of high quality orthologous genes in wheat and other species such as Brachypodium distachyon and Sorghum bicolor. You can interactively search and visualize the order of orthologous genes and their synteny conservation using our visualization tools.

Currently, POB includes information related to the following plant species:
