“…As such, the NP could be absorbed from the soil by the roots and then partly transferred to the above-ground parts, and then ultimately located throughout the whole plants. Similar observations were previously reported in studies on the uptake and translocation of pesticides in plants 27,28 .Figure 1Accumulation of NP in the shoots and roots of the tomato seedlings (means ± SD, n = 3). Data with the same letter did not differ significantly at the 5% level.…”

“…In fact, to improve their tolerability to various environmental stresses, plants are able to generate a set of protective and remediation mechanisms for the effective removal of ROS. Among these mechanisms, ROS-eliminating enzymes play an indispensable role and are often used as indicators of abiotic stresses 28,45 .…”

“…GST catalyses the covalent binding of various electrophilic xenobiotics to the sulphur atom in GSH, which is a classical detoxification pathway in plant tissues 28,58 . Not long ago, GST was reported to be a potent antidote to atrazine and ametryn in plants 28,30,59 . In addition, our recent study indicated that GST in wheat plants played an important role in the detoxification of simetryne 27 .…”

“…Several contaminants can be present in soil, such as pesticides, polycyclic aromatic hydrocarbons and heavy metals, which are ready to intrude into crop plants. Plants have evolved sophisticated defence mechanisms to counteract the stress induced by these toxicants 27,28 . The antioxidant system is a key constituent consisting of a variety of independent yet cooperating enzymes 29,30 .…”
Nonylphenol (NP) is one of the most worrisome and ubiquitous environmental endocrine disruptors. The tomato is one of the most important agricultural plants in the world. However, little is known about the toxicological effects of NP on tomato crops or the accommodative responses of tomato plants to NP stress. Thus, in this study, relevant tests were performed using pot experiments, and they indicated that when the NP concentration in the soil was elevated from 25 mg kg

to 400 mg kg

, NP was progressively accumulated by the tomato plants. The NP induced growth inhibition and a declined in the total chlorophyll content, and it aggravated membrane lipid peroxidation in tomato plants. When confronted with NP stress, the tomato plants correspondingly induced their antioxidant enzymes via both molecular and protein pathways to relieve the NP-induced oxidative stress. All the above results would be illuminating for developing strategies to address NP-induced damage to agricultural output, food quality and public health.

“…However these methods are usually associated with sample preparation techniques, crucial to remove matrix effects and even to obtain enriched extracts of trace analytes [16]. Some of the sample preparation techniques that have been applied include microwave-assisted solvent extraction [11], solidphase microextraction (SPME) [9,10,14], liquid-liquid extraction [17] or solid-phase extraction [8].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
