The glucosinolate/myrosinase system: variation in glucosinolates, hydrolysis products, transcript abundance, and quinone reductase bioactivity in Brassica sp. crops
Glucosinolates, and more specifically their hydrolysis products, are secondary metabolites present in Brassica crops that are important for plant defense from insects and pathogens. In addition, these compounds have long been associated with anti-cancer activity in mammals through the induction of …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
The relationships between host plant glucosinolates and feeding and growth of a polyphagous insect, the Bertha armyworm, Mamestra configurata Walker and field infestation levels of an oligophagous insect, the diamondback moth, Plutella xylostella L. were investigated. M. configurata reared on eight …

Digestive metabolism of glucosinolates: a novel approach using urinary markers for estimating the release of glucosinolate breakdown products in the gastro-intestinal tract of mammals.
Glucosinolates have been implicated as a mediator of the cancer-protective properties of cruciferous vegetables. Enzymatic hydrolysis of glucosinolates by plant or microbial myrosinase yields a range of metabolites including beneficial isothiocyanates. Little is known about the fate of …

Antioxidant Potential in Broccoli and Observations on Flavor in a Segregating Broccoli Population (Brassica Oleracea)
… a number of bioactive compounds including glucosinolates, S-methyl cysteine sulfoxide (SMCSO) and many antioxidants that may be responsible for this protective effect. However, glucosinolates and SMCSO are also thought to negatively impact flavor and consumer acceptance of the vegetable, …

Effects of Brassica on the human gut microbiota
… presence of sulphur-containing compounds, termed glucosinolates, which are associated with potential health benefits for humans. Glucosinolates are metabolised in the gut by members of the gut microbiota, producing biologically active breakdown products, such as isothiocyanates. The effects of …

Flavor Characterization of Broccoli Cultivars
… also suggest that SMCSO and aliphatic glucosinolates share common pathways in biosynthesis.

Genetic Constraints and the Evolution of Chemical Defenses in Multiple Tissues of Boechera stricta
… In my dissertation, I investigate how glucosinolates, biologically active secondary metabolites, evolve in multiple tissues of the crucifer Boechera stricta. I quantify variation in glucosinolate concentration and the relative ratio of each glucosinolate compound (hereafter called the …

Effectiveness of mustard short-cycle cover crops for management of Phytophthora capsici and Fusarium spp. in cucurbits
… not affected. In the greenhouse trial, thirteen glucosinolates were detected and quantified in both FBL and Tilney mustard cultivars. FBL roots had significantly lower total glucosinolate content (µmol/g) than FBL foliage. Conversely, Tilney roots had significantly higher glucosinolate content …

Dissecting the jasmonate singalling pathway in Arabidopsis thaliana
… β-glucosidases catalyse the breakdown of glucosinolates into glucose and sulphate releasing toxic by-products which play a role in plant defence against insects and pathogens.

The Overexpression of a Feedback -Insensitive Anthranilate Synthase in Arabidopsis and Tobacco
… The levels of the Trp-derived compounds indole glucosinolates were not altered in transgenic plants, suggesting that the increased Trp pool did not affect the synthesis of indole glucosinolates. Transgenic Arabidopsis also exhibited greater resistance than the wild type to all of the Trp and …

Evaluation of the induction of rat hepatic and pancreatic glutathione S-transferases by treatment with the cruciferous nitrile, cyanohydroxybutene
… (CHB) is a nitrile derived from glucosinolates commonly found in cruciferous plants. Glucosinolate derivatives are believed to provide protection against carcinogens by inducing detoxifying including the glutathione S-transferase isoenzymes (GSTs). The GSTs catalyze the …

GENETIC IMPROVEMENT OF CAMELINA SATIVA: DEVELOPMENT OF NEW VARIETIES AND EXPLORATION OF ITS POTENTIAL AS AN INTERMEDIATE CROP
… reduction of anti-nutritional compounds such as glucosinolates). He underlines the importance of genetic diversity and proposes two selection strategies: one that involves crossing spring varieties and the other that crosses spring and winter varieties. Breeding programs have shown that winter …

Microbial glucosinolate metabolism: Characterization of Enterococcus faecalis XL1 and functional analysis of a GH4 enzyme
Glucosinolates (GSLs), sulfur-containing plant metabolites abundant in cruciferous vegetables, are hydrolyzed to isothiocyanates (ITCs) – bioactive compounds with antimicrobial, anticancer, and anti-inflammatory properties. When plant myrosinases are inactivated by cooking, gut microbes become the …

EFFECTS OF MATURITY STAGES AND GROWING CONDITIONS ON PHYTOCHEMICAL PROFILE AND ANTIOXIDANT ABILITY OF BRASSICA VEGETABLES
… components in each, respectively. The aliphatic glucosinolates including sinigrin and glucoraphanin were predominant in the kale, broccoli, and red cabbage microgreens grown under both chamber and windowsill conditions. In addition, microwaved mature kale had a greater level of phytochemicals …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
… were tested: plants unable to produce aliphatic glucosinolates, plants impaired in the PAMP-triggered immune response and plants unable and over-expressed in methyl halides production and one group of Medicago mutants which are impaired in the mycorrhization ability. All these plant genotypes, …

Metabolomic approaches to understanding the auxin and ethylene response in Arabidopsis roots
… of specialized metabolites such as flavonols and glucosinolates change in abundance in response to both auxin and ethylene, there was little overlap with regard to the specific metabolites affected. These data will be integrated with information from transcriptomic and proteomic experiments to …

Evaluation of the nutritional value of canola meal, 00-rapeseed meal, and 00-rapeseed expellers fed to pigs
… that concentrations of sucrose, P, K, Zn, and glucosinolates are greater (P < 0.05) in 00-rapeseed meal than in canola meal. Concentrations of GE and acid hydrolyzed ether extract (AEE) are greater (P < 0.05) in 00-rapeseed expellers than in 00-rapeseed meal, but concentrations of CP, Thr, ash, …

Nutritional Evaluation Of New Reduced-Oligosaccharide Soybean Meal And Canola Meals Produced From New Varieties Of Canola Seeds For Poultry
… of the double low (low erucic acid and low glucosinolates) cultivars of canola has resulted in increased usages of canola meal (CM) in poultry diets. If the CM had more digestible energy, more protein and less glucosinolates, it would likely be more competitive in the world market. This …
