“…In plants from the phytoremediation systems, the fatty acid contents in the leaf and the corm were negatively affected by the THC level, but in contrast, for the root tissue, the effect was noticeably positive for a THC content below 340 g/Kg soil. The effect observed for the root tissue is consistent with reports for monoaxenic cultures of Cichorium intybus grown in the presence of Benzo[a]pyrene [ 27 ] and Zea mayz seedlings cultured in the presence of monoterpenes [ 37 ], where increases in the total fatty acid content in the roots after the xenobiotic application were observed. However, the results for the corm in the present study contrast with the study of Stoller and Weber [ 33 ], where significant increases in the fatty acid content in tubers from a cold tolerant variety of C .…”

“…It was hypothesized that the combination of the C18:3 fatty acid biosynthetic pathway with the production of corms might provide C . laxus with a superior ability to tolerate the weathered hydrocarbons’ toxicity by adjusting the antioxidant capability, thereby producing a higher amount of unsaturated fatty acids in a similar way as reported for the fatty acid content in chicory root cultures grown in presence of benzo(a)pyrene [ 27 ]. However, because no information was found about the effect of hydrocarbons on the fatty acid profile of C .…”

The Fatty Acid Profile Analysis of Cyperus laxus Used for Phytoremediation of Soils from Aged Oil Spill-Impacted Sites Revealed That This Is a C18:3 Plant Species

The effect of recalcitrant hydrocarbons on the fatty acid profile from leaf, basal corm, and roots of Cyperus laxus plants cultivated in greenhouse phytoremediation systems of soils from aged oil spill-impacted sites containing from 16 to 340 g/Kg total hydrocarbons (THC) was assessed to investigate if this is a C18:3 species and if the hydrocarbon removal during the phytoremediation process has a relationship with the fatty acid profile of this plant. The fatty acid profile was specific to each vegetative organ and was strongly affected by the hydrocarbons level in the impacted sites. Leaf extracts of plants from uncontaminated soil produced palmitic acid (C16), octadecanoic acid (C18:0), unsaturated oleic acids (C18:1-C18:3), and unsaturated eichosanoic (C20:2-C20:3) acids with a noticeable absence of the unsaturated hexadecatrienoic acid (C16:3); this finding demonstrates, for the first time, that C. laxus is a C18:3 plant. In plants from the phytoremediation systems, the total fatty acid contents in the leaf and the corm were negatively affected by the hydrocarbons presence; however, the effect was positive in root. Interestingly, under contaminated conditions, unusual fatty acids such as odd numbered carbons (C15, C17, C21, and C23) and uncommon unsaturated chains (C20:3n6 and C20:4) were produced together with a remarkable quantity of C22:2 and C24:0 chains in the corm and the leaf. These results demonstrate that weathered hydrocarbons may drastically affect the lipidic composition of C. laxus at the fatty acid level, suggesting that this species adjusts the cover lipid composition in its vegetative organs, mainly in roots, in response to the weathered hydrocarbon presence and uptake during the phytoremediation process.

“…This is the case in symbiotic arbuscular mycorrhizal fungi (AMF), which are largely documented for their ability to colonize root systems, regulate mineral nutrition and alleviate TE stress in several plant species (Smith and Read, 2008). The fungi, in exchange for carbohydrates, improve the water and mineral nutrition of the host plant (Smith and Read, 2008) and the plant's tolerance to abiotic stresses, such as pollution (Debiane et al, 2008(Debiane et al, , 2009(Debiane et al, , 2012. It has been demonstrated that AMF have a protective effect on plants growing in extreme environments, such as disturbed ecosystems and TE-contaminated sites (Ryszka and Turnau, 2007).…”

“…Once an arbuscular mycorrhiza (AM) association develop, mycorrhizal plants take up water and mineral nutrients, such as phosphorus (P), nitrogen (N), and trace elements more efficiently than non-mycorrhizal plants 6 7 . Meanwhile, AMF protect host plants against diverse biotic and abiotic stresses 8 . Most previous studies have found that AM fungi have positive effects on the dissipation of organic contaminants such as atrazine.…”

Arbuscular mycorrhizal fungi (AMF) protect host plants against diverse biotic and abiotic stresses, and promote biodegradation of various contaminants. In this study effect of Glomus mosseae/Medicago sativa mycorrhiza on atrazine degradation was investigated. It was observed that the atrazine degradation rates with any addition level in mycorrhizal treatments were all significantly higher than those in non- mycorrhizal treatments. When atrazine was applied at 20 mg kg−1, the removal efficiency was up to 74.65%. Therefore, G. mosseae can be considered as ideal inhabitants of technical installations to facilitate phytoremediation. Furthermore, a total of 10.4 Gb was used for de novo transcriptome assembly, resulting in a comprehensive data set for the identification of genes corresponding to atrazine stress in the AM association. After comparative analysis with edgeR, a total of 2,060 differential expressed genes were identified, including 570 up-regulated genes and 1490 down-regulated genes. After excluding ‘function unknown’ and ‘general function predictions only’ genes, 172 up-regulated genes were obtained. The differentially expressed genes in AM association with and without atrazine stress were associated with molecular processes/other proteins, zinc finger protein, intracellular/extracellular enzymes, structural proteins, anti-stress/anti-disease protein, electron transport-related protein, and plant growth associated protein. Our results not only prove AMF has important ecological significance on atrazine degradation but also provide evidence for the molecular mechanisms of atrazine degradation by AMF.
