Transformation of Rapeseed (Brassica napus L.) Plants with Sense and Antisense Constructs of the Fatty Acid Elongase Gene
The biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. One of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-CoA syn...
متن کاملA jojoba beta-Ketoacyl-CoA synthase cDNA complements the canola fatty acid elongation mutation in transgenic plants.
beta-Ketoacyl-coenzyme A (CoA) synthase (KCS) catalyzes the condensation of malonyl-CoA with long-chain acyl-CoA. This reaction is the initial step of the microsomal fatty acyl-CoA elongation pathway responsible for formation of very long chain fatty acids (VLCFAs, or fatty acids with chain lengths > 18 carbons). Manipulation of this pathway is significant for agriculture, because it is the bas...

متن کاملPorcine Fatty Acid Synthase Gene Polymorphisms Are Associated with Meat Quality and Fatty Acid Composition
We assessed the effects of single-nucleotide polymorphisms (SNPs) within the porcine fatty acid synthase (FASN) gene regarding meat quality and fatty acid composition in two pig populations: Korean native pigs (KNP) were crossed with Yorkshire (YS) F 2 , and KNP were crossed with Landrace (LR) F 2 . Direct DNA sequencing using eight KNP and eight YS pigs revealed two SNPs: c.265C>T (silent) in ...
متن کاملEnvironmental and Induced Mutations Influences on Oil Content, Oleic Acid and Erucic Acid in Rapeseed
A comparative study was conducted to see the mutational analysis for monounsaturated fatty acids in rapeseed (Brassica napus L.) mutant populations. By using gamma irradiation, a range of variability generated for oil content and fatty acid composition in rapeseed seeds. The induced genetic variability was analyzed for two consecutive years in two contrasting environments at elevations of 510 a...
