Schematic representation of the systems genetics approach to explore the potential of existing intraspecific variation for various grain quality traits on a genetic map using GWAS/QTL. Unravelling a holistic view of grain quality perturbation under stress requires the integration of knowledge from systems biology (regulatory networks and flux balance analysis), systems genetics, and comparative genomics to explore the perspectives of a genomics revolution in breeding to develop climate-resilient lines with superior grain quality.
