Metabolic regulations in lettuce root under combined exposure to perfluorooctanoic acid and perfluorooctane sulfonate in hydroponic media

Translocation, bioaccumulation, and distribution of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in plants

“…Increased PFAS levels in plant tissues induce metabolomic changes in vivo , such as changes in purine metabolism, tricarboxylic acid cycle (TCA cycle), glyoxylate and dicarboxylate metabolism, pyruvate metabolism, nitrogen metabolism, and linoleic acid (fatty acid) metabolism in lettuce roots following PFOA and PFOS exposure ( Li et al., 2020b ). As a result, 23 antioxidants present in the lettuce roots were significantly altered after exposure to PFASs, reducing levels of arbutin and cinnamic acid and increasing levels of caffeic, cycloheterophyllin, equol, homovanillic acid, and hydroxytyrosol ( Figure 4 ).…”

“…Equol, 6. Homovanillic acid, and 7. hydroxytyrosol) in lettuce root induced by (A and B) PFOA and PFOS exposure (A = control; B = 1000 ng/L of both PFOA and PFOS) Reproduced with permission from Li et al. (2020b) .…”

Effect of Nicotiana benthamiana exposed to long- or short-chain perfluoroalkyl substances: Levels, transfer and potential risk analysis

“…Tolerance had been widely used to evaluated the ability of crops under biological and abiotic stress. (CH Chen et al 2020; Li et al 2020) The difference between stress group and control group was more signi cant, which was manifested as weaker tolerance and greater damage to crops. In general, PFASs exposure levels were equal or greater than 15 mg/L, the tolerance of N. benthamiana decreased rapidly.…”

Soybean Metabolomics Based in Mass Spectrometry: Decoding the Plant’s Signaling and Defense Responses under Biotic Stress

“…39 As such, metabolomics enables new dimensions in the study of systems biology, allowing for a deep understanding of the intracellular and extracellular interactions of plant cells. 40 Plant metabolomics has been applied in different studies, such as in the evaluation of the metabolic profile at different growth stages, 41 changes in the metabolism of exposed plants to environmental contaminants, 42 alteration of the metabolome of plants in conditioned soil, 43 effect of fungicide on the metabolome of the plant, 44 and abiotic 45 and biotic stress. 46 Metabolomics strategies cover two main segments of analysis: targeted and untargeted.…”
