1. Bioactive Compounds and Antioxidant Activity in Leaves of Endemic and Native Isatis spp in Turkey
Abstract This study was undertaken to evaluate the health-promoting potentials of Isatis aucherii, Isatis buschiana, Isatis candolleana, Isatis tinctoria subsp. corymbosa and Isatis tinctoria. I. aucherii and I. candolleana are endemic, I. buschiana, I. tinctoria subsp. corymbosa are native in Turkey. While I. tinctoria is a well studied species, there is in

2. Variation of glucoraphanin and glucobrassicin: anticancer components in Brassica during processing
Effects of cold storage and three common cooking practices, blanching, sauteing, and microwave cooking at different time intervals, on the content of glucosinolate (GSL) anticancer components in six Brassica vegetables were investigated. Eleven GSLs including progoitrin, glucoraphanin, sinigrin, glucoalyssin, gluconapin, glucobrassicanapin, glucoerucin, gluc

3. Seleção de fungos filamentosos para a produção do mirosinase
A linhagem Aspergillus sp. NR46FB, isolada de solo através da técnica do ágar sulfato de bário-sinigrina, foi testada quanto à produção de mirosinase. O fungo degradou completamente o glicosinolato e produziu 3,19 U.mL-1 de mirosinase, após 48 h de cultivo. Devido à alta produção de mirosinase, esse novo isolado é um potente candidato para aplica

4. Genetic Control of Natural Variation in Arabidopsis Glucosinolate Accumulation
Glucosinolates are biologically active secondary metabolites of the Brassicaceae and related plant families that influence plant/insect interactions. Specific glucosinolates can act as feeding deterrents or stimulants, depending upon the insect species. Hence, natural selection might favor the presence of diverse glucosinolate profiles within a given species

5. Modulation of CYP79 Genes and Glucosinolate Profiles in Arabidopsis by Defense Signaling Pathways1
Glucosinolates are natural plant products that function in the defense toward herbivores and pathogens. Plant defense is regulated by multiple signal transduction pathways in which salicylic acid (SA), jasmonic acid, and ethylene function as signaling molecules. Glucosinolate content was analyzed in Arabidopsis wild-type plants in response to single or combi

6. Evolutionary dynamics of an Arabidopsis insect resistance quantitative trait locus
Glucosinolate profiles differ among Arabidopsis thaliana ecotypes, caused by the composition of alleles at several glucosinolate biosynthetic loci. One of these, GS-Elong, harbors a family of methylthioalkylmalate synthase (MAM) genes that determine the side chain length of aliphatic glucosinolate structures. Fine mapping reveals that GS-Elong constitutes an

7. Nitrile-specifier Proteins Involved in Glucosinolate Hydrolysis in Arabidopsis thaliana*S⃞
Glucosinolates are plant secondary metabolites present in Brassicaceae plants such as the model plant Arabidopsis thaliana. Intact glucosinolates are believed to be biologically inactive, whereas degradation products after hydrolysis have multiple roles in growth regulation and defense. The degradation of glucosinolates is catalyzed by thioglucosidases

8. The Plastidic Bile Acid Transporter 5 Is Required for the Biosynthesis of Methionine-Derived Glucosinolates in Arabidopsis thaliana[W]
Aliphatic glucosinolate biosynthesis is highly compartmentalized, requiring import of 2-keto acids or amino acids into chloroplasts for side chain elongation and export of the resulting compounds into the cytosol for conversion into glucosinolate. Aliphatic glucosinolate biosynthesis in Arabidopsis thaliana is regulated by three R2R3-MYB transcription factor

9. Glucosinolate Uptake by Developing Rapeseed Embryos 1
Embryos excised from the seed of rapeseed (Brassica napus L.) accumulated glucosinolate from the culture medium. Uptake was saturable, subject to inhibition, varied with the developmental stage of the embryo but correlated with the time of accumulation of glucosinolates in situ. It is suggested that a carrier-mediated transport system is operating in the dev

10. Involvement of Cytochrome P450 in Glucosinolate Biosynthesis in White Mustard (A Biochemical Anomaly).
One of the first steps in glucosinolate biosynthesis is the conversion of amino acids to their aldoximes. The biochemistry of this process is controversial, and several very different enzyme systems have been described. The major glucosinolate in white mustard (Sinapis alba) is sinalbin, which is derived from tyrosine via its aldoxime, and this conversion is

11. Study of the Role of Antimicrobial Glucosinolate-Derived Isothiocyanates in Resistance of Arabidopsis to Microbial Pathogens1
Crude aqueous extracts from Arabidopsis leaves were subjected to chromatographic separations, after which the different fractions were monitored for antimicrobial activity using the fungus Neurospora crassa as a test organism. Two major fractions were obtained that appeared to have the same abundance in leaves from untreated plants versus leaves from pl
