摘要
Polycyclic aromatic hydrocarbons (PAHs) are a type of organic pollutions that can accumulate in crops and hazard human health. This study used phenanthrene (PHE) as a model PAH and employed hydroponic experiments to illustrate the role of indole-3-acetic acid (IAA) in the regulation of PHE accumulation in wheat roots. At optimal concentrations, wheat roots treated with PHE+IAA showed a 46.9% increase in PHE concentration, whereas treatment with PHE+P-chlorophenoxyisobutyric acid resulted in a 38.77% reduction. Transcriptome analysis identified TaSAUR80-5A as the crucial gene for IAA-enhancing PHE uptake. IAA increases plasma membrane H
