Chemical Survey and Erucic Acid Content of Commercial Varieties of Nasturtium , Tropaeolum maju 5 L .
نویسنده
چکیده
Nasturtium (Tropaeolum majus L.) oil contains the highest levels of erucic acid of known seed oils (75-80%). A significant portion of the acid is attached to the 2-position of the glycerol, and trierucin is a major component (ca. 50%) of the oil. Seeds from eleven varieties of commercially available garden nasturtium (T. majus) were screened for oil content, erucic acid levels and fatty acid distribution. Oil contents ranged from ca. 6 to 11%, and erucic acid levels in the oils ranged from 62 to 80%. One sample of T. speciosum was also analyzed, and contained 28% oil, fatty acids from C16 to C2S and triglycerides up to Cn .

Seed-specific heterologous expression of a nasturtium FAE gene in Arabidopsis results in a dramatic increase in the proportion of erucic acid.
The fatty acid elongase [often designated FAE or beta-(or 3-) ketoacyl-CoA synthase] is a condensing enzyme and is the first component of the elongation complex involved in synthesis of erucic acid (22:1) in seeds of garden nasturtium (Tropaeolum majus). Using a degenerate primers approach, a cDNA of a putative embryo FAE was obtained showing high homology to known plant elongases. This cDNA co...
متن کاملInfluence of drought stress and Chitosan on fatty acid compounds of rapeseed varieties
In order to investigate the changes in fatty acids composition of rapeseed lines under Chitosan application, a factorial split-plot experiment was conducted based on RCBD in 3 replications during 2 years (2014-2016) in Karaj, Iran. Irrigation and Chitosan as main plots and cultivar in sub-plots were considered. In this study, treatmen...
متن کاملErucic acid as the factor in rape oil affecting adrenal cholesterol in the rat.
In a previous communication it was reported that feeding rape oil to rats for a month as 25 per cent by weight of their diet caused a 3to 4-fold increase in the amount of cholesterol in their adrenals (1). A similar effect has been obtained by feeding large amounts of turnip seed oil, nasturtium seed oil, or a weed seed oil obtained chiefly from species of Brassica. Other fats and oils have gen...
متن کاملEffect of Gibberellic Acid on the Senescence of Leaf Discs of Nasturtium (Tropaeolum majus).
Aging in leaves is characterized by a decrease in chlorophyll content and an accompanying loss of protein and ribonucleic acid. It is well known that these symptoms of senescence occur at an accelerated rate in excised mature leaves and in leaf discs floated on water. In recent years it has been established that several chemical substances retard the senescence of leaves. Among the compounds wh...
متن کاملTransformation 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...
