Genome-Wide Association Analyses Identify Hydrogen Peroxide-Responsive Loci in Wheat Diversity.

ABSTRACT: Hydrogen peroxide (H₂O₂) is a signaling molecule that plays a crucial role in plant growth and development against different abiotic stresses. Identifying genetic factors associated with H₂O₂ regulation and homeostasis can provide valuable insights for improving stress tolerance. Here, we explored genetic diversity of root and shoot traits mediated by H₂O₂ using a global diversity panel of 150 bread wheat cultivars. The H₂O₂ treatment significantly reduced root and shoot growth. We calculated relative values and stress tolerance index (STI) of root and shoot traits and performed genome-wide association studies (GWAS). This led to identification of 108 marker-trait associations including the topmost asso
