Genome‐wide scan reveals <scp>CYP450</scp> metabolism and stress response regulation underlying sulfosulfuron resistance in <scp> <i>Bromus tectorum</i> </scp>
Non-target site resistance for sulfosulfuron is present in B. tectorum populations of the inland PNW. A heat shock-related protein 70 regulator and an auxin response factor gene was near the SNP that explained 48% of the variation in the GWAS, indicating auxin regulation and stress response pathways are involved in the resistance of B. tectorum populations to sulfosulfuron. The heat shock-factor protein 70 regulated by the heat shock-related protein 70 regulator was found on another significant SNP and the SNPs those two genes were on have a significant interaction. Additionally, the GWAS analysis indicated CYP450 genes are likely involved in resistance. © 2025 Society of Chemical Industry.
