Introduction Glucosinolates are a class of compounds found in the plant family Brassicaceae and particularly in rapeseed. They are considered as responsible for the detrimental effects (palatability and toxic symptoms) observed when rapeseed meal is used for feeding (Fenwick et al., 1983). The analysis of glucosinolates appears to be a good evaluation of rapeseed anti-nutritional potential. Dur...

The feasibility of using untreated rapeseed meal as a nitrogen source for iturin A production by Bacillus subtilis 3-10 in submerged fermentation was first evaluated by comparison with two different commercial nitrogen sources of peptone and ammonium nitrate. A significant promoting effect of rapeseed meal on iturin A production was observed and the maximum iturin A concentration of 0.60 g/L wa...

Efficient molecular markers for the selection of rapeseed genetic materials with high seed oil content and ideal fatty acid (FA) composition are preferred by rapeseed breeders. Recently, we reported the molecular mechanism of TRANSPARENT TESTA 2 (TT2) in inhibiting seed FA biosynthesis in Arabidopsis. However, evidence showing the association of rapeseed TT2 homologs and seed FA production are ...

MicroRNAs (miRNAs) are a class of small noncoding RNA that, through mediating posttranscriptional gene regulation, play a critical role in nearly all biological processes. Over the last decade it has become apparent that plant miRNAs may serve as a novel functional component of food with therapeutic effects including anti-influenza and antitumor. Rapeseed bee pollen has good properties in enhan...

Paraquat (1, r-dimethyl-4,4'-bipyridium dichloride), a brown syrupy liquid is an effective herbicide that has low chronic toxicity because of its rapid deactivation on contact with soil. A high dose of paraquat or severe poisoning has a poor prognosis. At present there is no specific antidote to paraquat poisoning, hence the need to focus on prevention and in case of exposure or ingestion, aggr...

In this paper a review of the most important results on the paraquat resistance mechanism of weeds is given, with special respect on horseweed Conyza canadensis (L.) Cronq. There is no difference between susceptible and resistant plants in the activity of antioxidant enzymes and in the penetration of paraquat into the chloroplasts. The paraquat resistance is primarily based on higher expression...

Background Paraquat is a broad spectrum herbicide used particularly in burndown, pre-plant of row crops and the pre-harvest desiccation some crops. In Brazil, paraquat was re-evaluated by Anvisa, leading to prohibition production sales on September 22, 2020, until July 31, 2021. Objective The objective this review characterize use Brazil describe status other countries, agronomic implications i...

BACKGROUND The plasma concentration of paraquat is closely related to the prognosis of patients with paraquat toxication, and the most common cause of death from paraquat poisoning is multiple organ failure (MOF). This study aimed to evaluate therapeutic effect of smecta on the plasma concentrations of paraquat and multi-organ injury induced by paraquat intoxication in rats. METHODS A total o...

Wld(S) is a fusion protein with NAD synthesis activity, and has been reported to protect axonal and synaptic compartments of neurons from various mechanical, genetic and chemical insults. However, whether Wld(S) can protect non-neuronal cells against toxic chemicals is largely unknown. Here we found that Wld(S) significantly reduced the cytotoxicity of bipyridylium herbicides paraquat and diqua...

Poisoning by paraquat herbicide is a major medical problem in parts of Asia while sporadic cases occur elsewhere. The very high case fatality of paraquat is due to inherent toxicity and lack of effective treatments. We conducted a systematic search for human studies that report toxicokinetics, mechanisms, clinical features, prognosis and treatment. Paraquat is rapidly but incompletely absorbed ...
