摘要： Phenylalanine (Phe), an aromatic amino acid, is a key precursor of flavonoids, which are crucial for plant growth and development. Arogenate dehydratase (ADT) catalyzes the final step in Phe biosynthesis. This study identified eleven ADT genes in G. hirsutum, twelve in G. barbadense, six in G. arboreum, and six in G. raimondii. Among them, GhADT5 exhibited the highest upregulation under alkali stress. Silencing GhADT5 using virus-induced gene silencing (VIGS) reduced cotton tolerance to alkali stress. GhADT5 silencing also led to decreased plant phenylalanine content, total flavonoid content, and activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD). These reductions caused intracellular accumulation of Malondialdehyde (MDA) and reactive oxygen species (ROS). This oxidative damage ultimately reduced tolerance to alkali stress. In addition, silenced plants displayed reduced stomatal aperture, cellular deformation, and irregular intercellular breaks in the leaf epidermis. In summary, these findings suggest that GhADT5 may enhance resistance to alkali stress by regulating enzymatic and non-enzymatic antioxidant systems. This study highlights the role of GhADT5 under alkali stress and provides novel insights for breeding cotton varieties with improved stress tolerance.
