- Intervention effect 2-CEES exposure caused significant morphological changes in bryophytes.
- Intervention effect 2-CEES markedly disrupted the photosynthetic activity of Physcomitrella patens.
- Intervention effect 2-CEES markedly disrupted the photosynthetic activity of Taxiphyllum taxirameum.
- Intervention effect 2-CEES at 600 mg/m³ for 72 hr produced pronounced changes in metabolite expression across all three bryophytes.
- Intervention effect 2-CEES significantly perturbed amino acid, nucleic acid and carbohydrate metabolism in Bryum argenteum.
- Intervention effect 2-CEES significantly perturbed lipid metabolism in Bryum argenteum.
- Intervention effect 2-CEES significantly perturbed amino acid, nucleic acid and carbohydrate metabolism in Physcomitrella patens.
- Intervention effect 2-CEES significantly perturbed lipid metabolism in Physcomitrella patens.
- Intervention effect 2-CEES caused primary disruptions in lipid metabolism, terpenoid and polyketide metabolism, and membrane transport in Taxiphyllum taxirameum.
- Association Aberrant synthesis of L-Glutamyl-tRNA(Glu) may correlate with impaired chlorophyll production in bryophytes.
- Mechanism Molecular docking suggests 2-CEES binds key enzymes (glutathione S-transferase and Glu-tRNA synthetase) through hydrogen bonds, interfering with substrate-binding activity and disrupting metabolic pathways.
