A plastidic transporter involved in aliphatic glucosinolate biosynthesis.
The distinctive flavors and anticarcinogenic properties of cruciferous vegetables are largely due to the presence of glucosinolates. These sulfur-rich metabolites are derived from one of several amino acids via three stages: (1) elongation of the amino acid side chain; (2) formation of the core glucosinolate skeleton; and (3) secondary modification of the side chain (reviewed in Grubb and Abel,...
متن کاملSubclade of flavin-monooxygenases involved in aliphatic glucosinolate biosynthesis.
Glucosinolates (GSLs) are amino acid-derived secondary metabolites with diverse biological activities dependent on chemical modifications of the side chain. We previously identified the flavin-monooxygenase FMO(GS-OX1) as an enzyme in the biosynthesis of aliphatic GSLs in Arabidopsis (Arabidopsis thaliana) that catalyzes the S-oxygenation of methylthioalkyl to methylsulfinylalkyl GSLs. Here, we...
متن کاملGlucose signalling positively regulates aliphatic glucosinolate biosynthesis
The effects of glucose on aliphatic glucosinolate biosynthesis in Arabidopsis thaliana were investigated in this study by using mutants related to aliphatic glucosinolate biosynthesis and regulation, as well as glucose signalling. The results showed that glucose significantly increased the contents of individual and total aliphatic glucosinolates. Expression of MYB28 and MYB29, two key transcri...
متن کاملThree genes encoding AOP2, a protein involved in aliphatic glucosinolate biosynthesis, are differentially expressed in Brassica rapa
The glucosinolate biosynthetic gene AOP2 encodes an enzyme that plays a crucial role in catalysing the conversion of beneficial glucosinolates into anti-nutritional ones. In Brassica rapa, three copies of BrAOP2 have been identified, but their function in establishing the glucosinolate content of B. rapa is poorly understood. Here, we used phylogenetic and gene structure analyses to show that B...
متن کاملMolecular Characterization of MYB28 Involved in Aliphatic Glucosinolate Biosynthesis in Chinese Kale (Brassica oleracea var. alboglabra Bailey)
Glucosinolates are Brassicaceae-specific secondary metabolites that act as crop protectants, flavor precursors, and cancer-prevention agents, which shows strong evidences of anticarcinogentic, antioxidant, and antimicrobial activities. MYB28, the R2R3-MYB28 transcription factor, directly activates genes involved in aliphatic glucosinolate biosynthesis. In this study, the MYB28 homology (BoaMYB2...
