Differential expression of major genes involved in the biosynthesis of aliphatic glucosinolates in intergeneric Baemoochae (Brassicaceae) and its parents during development.[Pubmed:31792713]

Plant Mol Biol. 2020 Jan;102(1-2):171-184.

KEY MESSAGE: Thus study found the temporal and spatial relationship between production of aliphatic glucosinolate compounds and the expression profile of glucosinolate-related genes during growth and development in radish, Chinese cabbage, and their intergeneric hybrid baemoochae plants. Glucosinolates (GSLs) are one of major bioactive compounds in Brassicaceae plants. GSLs play a role in defense against microbes as well as chemo-preventative activity against cancer, which draw attentions from plant scientists. We investigated the temporal relationship between production of aliphatic Glucosinolate (GSLs) compounds and the expression profile of GSL related genes during growth and development in radish, Chinese cabbage, and their intergeneric hybrid, baemoochae. Over the complete life cycle, Glucoraphasatin (GRH) and glucoraphanin (GRE) predominated in radish, whereas gluconapin (GNP), glucobrassicanapin (GBN), and glucoraphanin (GRA) abounded in Chinese cabbage. Baemoochae contained intermediate levels of all GSLs studied, indicating inheritance from both radish and Chinese cabbage. Expression patterns of BCAT4, CYP79F1, CYP83A1, UGT74B1, GRS1, FMOgs-ox1, and AOP2 genes showed a correlation to their corresponding encoded proteins in radish, Chinese cabbage, and baemoochae. Interestingly, there is a sharp change in gene expression pattern involved in side chain modification, particularly GRS1, FMOgs-ox1, and AOP2, among these plants during the vegetative and reproductive stage. For instance, the GRS1 was strongly expressed during leaf development, while both of FMOgs-ox1 and AOP2 was manifested high in floral tissues. Furthermore, expression of GRS1 gene which is responsible for GRH production was predominantly expressed in leaf tissues of radish and baemoochae, whereas it was only slightly detected in Chinese cabbage root tissue, explaining why radish has an abundance of GRH compared to other Brassica plants. Altogether, our comprehensive and comparative data proved that aliphatic GSLs biosynthesis is dynamically and precisely regulated in a tissue- and development-dependent manner in Brassicaceae family members.

Bunias erucago L.: Glucosinolate Profile and In Vitro Biological Potential.[Pubmed:30791395]

Molecules. 2019 Feb 19;24(4). pii: molecules24040741.

Bunias erucago belongs to the Brassicaceae family, which represents a forgotten crop of the Euro-Mediterranean area. The aim of the present study was to determine the glucosinolate profile in different plant parts and biological properties (antioxidant, anticholinesterase, and cytotoxic activities) of the isolates containing glucosinolate breakdown products. The chemical profiles were determined by using HPLC-PDA-MS/MS of desulfoglucosinolates and GC-MS of glucosinolate degradation products. The analysis of B. erucago showed the presence of seven glucosinolates: gluconapin (1), Glucoraphasatin (2), glucoraphenin (3), glucoerucin (4), glucoraphanin (5), glucotropaeolin (6), and glucosinalbin (7). The total glucosinolate content ranged from 7.0 to 14.6 micromol/g of dry weight, with the major glucosinolate glucosinalbin in all parts. The antioxidant activity of all volatile isolates was not notable. At a tested concentration of 227 mug/mL, flower hydro-distillate (FH) showed good AChE inhibition, i.e., 40.9%, while root hydro-distillate (RH) had good activity against BChE, i.e., 54.3%. FH showed the best activity against both tested human bladder cancer cell lines, i.e., against T24 after 72 h, which have IC50 of 16.0 mug/mL, and against TCCSUP after 48 h with IC50 of 7.8 mug/mL, and can be considered as highly active. On the other hand, RH showed weak activity against tested cancer cells.

Comparative analysis of glucosinolates and metabolite profiling of green and red mustard (brassica juncea) hairy roots.[Pubmed:30148032]

3 Biotech. 2018 Sep;8(9):382.

Here, accumulation of glucosinolates and expression of glucosinolates biosynthesis genes in green and red mustard hairy roots were identified and quantified by HPLC and qRT-PCR analyses. The total glucosinolates content of green mustard hairy root (10.09 microg/g dry weight) was 3.88 times higher than that of red mustard hairy root. Indolic glucosinolates (glucobrassicin, 4-methoxyglucobrassicin, and neoglucobrassicin) in green mustard were found at 30.92, 6.95, and 5.29 times higher than in red mustard hairy root, respectively. Conversely, levels of glucotropaeolin (aromatic glucosinolate) was significantly higher in red mustard than in green mustard. Accumulation of Glucoraphasatin, an aliphatic glucosinolate, was only observed only in red mustard hairy roots. Quantitative real-time PCR analysis showed that the expression level of genes related to aliphatic and aromatic glucosinolate biosynthesis were higher in red mustard, exception BjCYP83B. The expression of BjCYP79B2, which encodes a key enzyme involved in the indolic glucosinolate biosynthetic pathway, was higher in green mustard than in red mustard. Additionally, to further distinguish between green mustard and red mustard hairy roots, hydrophilic and lipophilic compounds were identified by gas chromatography-mass spectrometry and subjected to principal component analysis. The results indicated that core primary metabolites and glucosinolate levels were higher in the hairy roots of green mustard than in those of red mustard.

The mechanism of deterioration of the glucosinolate-myrosynase system in radish roots during cold storage after harvest.[Pubmed:28530612]

Food Chem. 2017 Oct 15;233:60-68.

The hydrolysis of glucosinolates (GSLs) by myrosinase yields varieties of degradation products including isothiocyanates (ITCs). This process is controlled by the glucosinolate-myrosinase (G-M) system. The major ITCs in radish roots are raphasatin and sulforaphene (SFE), and the levels of these compounds decrease during storage after harvest. We investigated the G-M system to understand the mechanism behind the decrease in the ITCs in radish roots. Six varieties of radish roots were stored for 8weeks at 0-1.5 degrees C. The concentrations of GSLs (Glucoraphasatin and glucoraphenin) were maintained at harvest levels without significant changes during the storage period. However, SFE concentration and myrosinase activity remarkably decreased for 8weeks. Pearson correlation analysis between ITCs, GSLs, and myrosinase activity showed that a decrease of SFE during storage had a positive correlation with a decrease in myrosinase activity, which resulted from a decrease of ascorbic acid but also a decrease of myrosinase activity-related gene expressions.

Development of an efficient glucosinolate extraction method.[Pubmed:28344636]

Plant Methods. 2017 Mar 21;13:17.

BACKGROUND: Glucosinolates, anionic sulfur rich secondary metabolites, have been extensively studied because of their occurrence in the agriculturally important brassicaceae and their impact on human and animal health. There is also increasing interest in the biofumigant properties of toxic glucosinolate hydrolysis products as a method to control agricultural pests. Evaluating biofumigation potential requires rapid and accurate quantification of glucosinolates, but current commonly used methods of extraction prior to analysis involve a number of time consuming and hazardous steps; this study aimed to develop an improved method for glucosinolate extraction. RESULTS: Three methods previously used to extract glucosinolates from brassicaceae tissues, namely extraction in cold methanol, extraction in boiling methanol, and extraction in boiling water were compared across tissue type (root, stem leaf) and four brassicaceae species (B. juncea, S. alba, R. sativus, and E. sativa). Cold methanol extraction was shown to perform as well or better than all other tested methods for extraction of glucosinolates with the exception of Glucoraphasatin in R. sativus shoots. It was also demonstrated that lyophilisation methods, routinely used during extraction to allow tissue disruption, can reduce final glucosinolate concentrations and that extracting from frozen wet tissue samples in cold 80% methanol is more effective. CONCLUSIONS: We present a simplified method for extracting glucosinolates from plant tissues which does not require the use of a freeze drier or boiling methanol, and is therefore less hazardous, and more time and cost effective. The presented method has been shown to have comparable or improved glucosinolate extraction efficiency relative to the commonly used ISO method for major glucosinolates in the Brassicaceae species studied: sinigrin and gluconasturtiin in B. juncea; sinalbin, glucotropaeolin, and gluconasturtiin in S. alba; glucoraphenin and Glucoraphasatin in R. sativus; and glucosatavin, glucoerucin and glucoraphanin in E. sativa.

Metabolic Activity of Radish Sprouts Derived Isothiocyanates in Drosophila melanogaster.[Pubmed:26901196]

Int J Mol Sci. 2016 Feb 18;17(2):251.

We used Drosophila melanogaster as a model system to study the absorption, metabolism and potential health benefits of plant bioactives derived from radish sprouts (Raphanus sativus cv. Rambo), a Brassicaceae species rich in glucosinolates and other phytochemicals. Flies were subjected to a diet supplemented with lyophilized radish sprouts (10.6 g/L) for 10 days, containing high amounts of glucoraphenin and Glucoraphasatin, which can be hydrolyzed by myrosinase to the isothiocyanates sulforaphene and raphasatin, respectively. We demonstrate that Drosophila melanogaster takes up and metabolizes isothiocyanates from radish sprouts through the detection of the metabolite sulforaphane-cysteine in fly homogenates. Moreover, we report a decrease in the glucose content of flies, an upregulation of spargel expression, the Drosophila homolog of the mammalian PPARgamma-coactivator 1 alpha, as well as the inhibition of alpha-amylase and alpha-glucosidase in vitro. Overall, we show that the consumption of radish sprouts affects energy metabolism in Drosophila melanogaster which is reflected by lower glucose levels and an increased expression of spargel, a central player in mitochondrial biogenesis. These processes are often affected in chronic diseases associated with aging, including type II diabetes mellitus.

Root Glucosinolate Profiles for Screening of Radish (Raphanus sativus L.) Genetic Resources.[Pubmed:26672790]

J Agric Food Chem. 2016 Jan 13;64(1):61-70.

Radish (Raphanus sativus L.), a root vegetable, is rich in glucosinolates (GLs), which are beneficial secondary metabolites for human health. To investigate the genetic variations in GL content in radish roots and the relationship with other root phenotypes, we analyzed 71 accessions from 23 different countries for GLs using HPLC. The most abundant GL in radish roots was Glucoraphasatin, a GL with four-carbon aliphatic side chain. The content of Glucoraphasatin represented at least 84.5% of the total GL content. Indolyl GL represented only 3.1% of the total GL at its maximum. The principal component analysis of GL profiles with various root phenotypes showed that four different genotypes exist in the 71 accessions. Although no strong correlation with GL content and root phenotype was observed, the varied GL content levels demonstrate the genetic diversity of GL content, and the amount that GLs could be potentially improved by breeding in radishes.

4-Methylsulfanyl-3-butenyl isothiocyanate derived from glucoraphasatin is a potent inducer of rat hepatic phase II enzymes and a potential chemopreventive agent.[Pubmed:21960141]

Arch Toxicol. 2012 Feb;86(2):183-94.

The objective of this study was to establish whether the phytochemical Glucoraphasatin, a glucosinolate present in cruciferous vegetables, and its corresponding isothiocyanate, 4-methylsulfanyl-3-butenyl isothiocyanate, up-regulate enzymes involved in the detoxification of carcinogens and are thus potential chemopreventive agents. Glucoraphasatin and myrosinase were isolated and purified from Daikon sprouts and Sinapis alba L., respectively. Glucoraphasatin (0-10 muM) was incubated for 24 h with precision-cut rat liver slices in the presence and absence of myrosinase, the enzyme that converts the glucosinolate to the isothiocyanate. The intact glucosinolate failed to influence the O-dealkylations of methoxy- and ethoxyresorufin or the apoprotein expression of CYP1 enzymes. Supplementation with myrosinase led to an increase in the dealkylation of methoxyresorufin, but only at the highest concentration of the glucosinolate, and CYP1A2 expression. In the absence of myrosinase, Glucoraphasatin caused a marked increase in epoxide hydrolase activity at concentrations as low as 1 muM paralleled by a rise in the enzyme protein expression; at the highest concentration only, a rise was also observed in glucuronosyl transferase activity, but other phase II enzyme systems were unaffected. Addition of myrosinase to the Glucoraphasatin incubation maintained the rise in epoxide hydrolase and glucuronosyl transferase activities, further elevated quinone reductase and glutathione S-transferase activities, and increased total glutathione concentrations. It is concluded that at low concentrations, Glucoraphasatin, either intact and/or through the formation of 4-methylsulfanyl-3-butenyl isothiocyanate, is a potent inducer of hepatic enzymes involved in the detoxification of chemical carcinogens and merits further investigation for chemopreventive activity.
