Accumulation of γ-aminobutyric acid and transcription of glutamate decarboxylase in Brassica juncea (L.) Czern
Mustard leaf (Brassica juncea (L.) Czern.) using as material of a traditional fermented vegetable food (Kimchi) in Korea, is one of the important vegetables. Two cultivars of mustard (red and green) were grown in the experimental farm of Chungnam National University and allowed them to grow until flowering stage. In this study, the variability of γ-aminobutyric acid (GABA) content and mRNA tran...
متن کاملTwo FAD3 desaturase genes control the level of linolenic acid in flax seed.
Industrial oil flax (Linum usitatissimum) and edible oil or solin flax differ markedly in seed linolenic acid levels. Despite the economic importance of low-linolenic-acid or solin flax, the molecular mechanism underlying this trait has not been established. Two independently inherited genes control the low-linolenic-acid trait in flax. Here, we identified two genes, LuFAD3A and LuFAD3B that en...
متن کاملApplication of a delta-6 desaturase with α-linolenic acid preference on eicosapentaenoic acid production in Mortierella alpina
BACKGROUND Delta-6 desaturase (FADS6) is a key bifunctional enzyme desaturating linoleic acid (LA) or α-linolenic acid (ALA) in the biosynthesis of polyunsaturated fatty acids (PUFAs). In previous work, we analyzed the substrate specificity of two FADS6 enzymes from Mortierella alpina ATCC 32222 (MaFADS6) and Micromonas pusilla CCMP1545 (MpFADS6), which showed preference for LA and ALA, respect...
متن کاملVariability of Fatty Acid Composition in Interspecific Hybrids of Mustard Brassica Juncea and Brassica Napus
In Sri Lanka, mustard (Brassica juncea) is cultivated as a subsidiary crop for the seeds used as a condiment in cooking. In the Indian sub-continent, however, it is an important oilseed crop used as a source of vegetable oil. Mustard has over 45% erucic acid (C22:1) which is unsuitable nutritionally for human consumption. The Brassica oilseed species, B. napus and B. campestris, were developed ...
متن کاملObesity resistance and deregulation of lipogenesis in Δ6-fatty acid desaturase (FADS2) deficiency.
Δ-6-fatty acid desaturase (FADS2) is the key enzyme in the biosynthesis of polyunsaturated fatty acids (PUFAs), the essential structural determinants of mammalian membrane lipid-bilayers. We developed the auxotrophic fads2(-/-) mouse mutant to assess the enigmatic role of ω3- and ω6-PUFAs in lipid homeostasis, membrane structure and function. Obesity resistance is another major phenotype of the...
