“…It remains an interesting question why the reaction took place in wheat cells but not in soybean cells. The conversion of PCP to tetrachlorocatechol may resemble the radical-type conversion of benzo[a]pyrene to benzo[a]pyrene quiñones by plant microsomes (Trenck and Sandermann, 1980) as well as by rat liver microsomal lipid peroxidation products (Morgenstern et al, 1981). NADPH-induced lipid peroxidation in liver microsomes also converted aldrin to dieldrin (Lang and Maier, 1986), a reaction often described in plant systems (Dohn and Krieger, 1981;Dennis and Kennedy, 1986).…”

“…Pollutants above a certain level can be toxic to both the plants and the associated microorganisms (van Dillewijn et al. , 2008), plant metabolism can transform the contaminant (at least temporarily) into a more toxic chemical (Trenck and Sandermann, 1980; Hughes et al. , 1997) or the plant can mobilize the contaminant from the soil to an aerial part where it can be introduced into the food chain.…”

SummaryWith the increase in quality of life standards and the awareness of environmental issues, the remediation of polluted sites has become a priority for society. Because of the high economic cost of physico‐chemical strategies for remediation, the use of biological tools for cleaning‐up contaminated sites is a very attractive option. Rhizoremediation, the use of rhizospheric microorganisms in the bioremediation of contaminants, is the biotechnological approach that we explore in this minireview. We focus our attention on bacterial interactions with the plant surface, responses towards root exudates, and how plants and microbes communicate. We analyse certain strategies that may improve rhizoremediation, including the utilization of endophytes, and finally we discuss several rhizoremediation strategies that have opened ways to improve biodegradation.

“…Quinones of benzo[a]pyrene identified by v.d. Trenck and Sandermann (1980) were supposed to arise by (abiotic) autoxidation of a hydroxylated derivative. Thus, the present unequivocal identification of 1-HO-P as a primary phase I product of pyrene supports previously published suppositions.…”

“…In the plant metabolism of endogenous and exogenous compounds, hydroxylations of aromatic rings are common and may be catalyzed by cytochrome P-450 dependent systems, peroxidases, or hydroperoxidases (Dohn and Krieger, 1981;Cole, 1983;Sandermann, 1994). Oxidation of benzo[a]pyrene was demonstrated with microsomal fractions from pea and soybean (v.d. Trenck and Sandermann, 1980).…”

The metabolism of the four-ringed polycyclic aromatic hydrocarbon (PAH) pyrene was investigated using cell suspension cultures of soybean, wheat, purple foxglove, and jimsonweed and callus cultures of soybean and foxglove. In all species, nonextractable residues were found (soybean, jimsonweed, and foxglove suspensions, <10% of applied 14C; soybean and foxglove callus cultures, 20−25%; wheat, 30−40%); soluble metabolites were detected in only foxglove and wheat. About 90% of applied pyrene was transformed in wheat. Corresponding data from soybean and foxglove callus cultures were about 30% and those from soybean, jimsonweed, and foxglove suspensions about 7%. In foxglove, 1-hydroxypyrene methyl ether was identified as the main metabolite, whereas a complex mixture of carbohydrate conjugates of 1-hydroxypyrene was found in wheat. Due to the present results, crop and wild plants may be metabolic sinks for PAHs in the environment. Concentrations and toxicological implications of 1-hydroxypyrene, its derivatives, and analogous metabolites of other PAHs should be investigated. Keywords: Pyrene metabolism; cell-suspension and callus cultures of soybean, wheat, purple foxglove and jimsonweed; hydroxylation; O-methylation; carbohydrate conjugates
