“…At the beginning of the era of rape modification, erucic acid occurred extensively in seed oils of the mustard family ( Cruciferae ) and distinguished these from most other vegetable oils which generally contain fatty acids with 16 and 18 carbon atoms . Erucic acid ( cis ‐13‐docosenoic acid, C22:1) is a long chain monounsaturated fatty acid with 22 carbon atoms, with a double bound at the cis‐13 position of the carbon chain . It is built‐in the TAG molecules.…”

“…The enzyme acyl‐CoA elongase, which is responsible for erucic acid biosynthesis, is situated in the endoplasmic reticulum. The elongation stage studied in Lunaria annua includes the following steps: condensation of oleoyl‐CoA and malonyl‐CoA and creation of 3‐ketoacyl‐CoA; reduction of 3‐ketoacyl CoA to 3‐hydroxyacyl‐CoA; dehydration of 3‐hydroxyacyl‐CoA and 2,3 transenoyl‐CoA reduction …”

Brassica napus is cultivated largely as a winter or semi‐winter form in Europe and Asia, respectively, whereas spring‐sown rape types are more adapted to the climatic conditions in Canada, northern Europe, and Australia. This plant, the third most important oil crop in the world after maize and oil palm, has had a unique history among those crops that have been targets of breeding and genetic modification. Although agronomy and genetic manipulations of B. napus plants to create seed with substantially no erucic acid content in the seed oil and meal largely free from aliphatic glucosinolates were major breakthroughs, opportunities for further advances in the reduction of antinutritive compounds/enhancement of bioactive compounds, in oil and meal health safety and quality, as well as in agronomic performance and pest resistance, are still greater today than they have ever been. Understanding and application of genetic control for key agronomic traits in B. napus, such as seed oil composition and concentration as well as their environmental interactions, are the main targets, which will underpin the development of the crop for cultivation in an extensive range of environments. It is also needed to improve phytochemical content through traditional breeding programs or through bioengineering of the phenylpropanoid pathway, leading to desirable secondary metabolite accumulation. This paper is a review of modifications (in the field of biotechnology, agronomy, and processing) that have been applied to improve the nutritional value of B. napus L. Practical Applications: This paper has value for people starting their scientific work in the field related to the B. napus biotechnology and nutritional value of vegetable oils. In addition, it is a current compedium of knowledge for people working professionally in the oil industry. Moreover, this article is a cross‐section of the current achievements of genetic engineering in improving the composition of rapeseed and indicates key publications on this subject. Brassica napus L., the third most important oil crop in the world after maize and oil palm, has a unique history among those crops that are targets of breeding and genetic modification. Effective tools of processing, biotechnology, and agronomy are essential to produce rapeseed oil with a high amount of bioactive compounds and continue to be employed in strengthening the product versatility.

“…Erucic acid (cis-13-docosenoic acid, C22:1) is a straight-chained mono-unsaturated very-long-chain fatty acid (VLCFA) with 22 carbon atoms and a double bond at the cis-13 position of the carbon chain. Biosynthesis of this fatty acid involves chain elongation of oleic acid (cis-9-octadecenoic acid, C18:1) to gondoic acid (cis-11-eicosenoic acid, C20:1) and then to C22:1 (Sanyal et al 2015). This reaction is catalyzed by ß-ketoacyl-CoA synthase (KCS), a membrane-bound enzyme that utilizes malonyl-CoA as the source of the two carbon atoms added in each cycle (Griffiths et al 1998).…”

“…Compared to low-erucic Brassica oils, high erucic oils have a higher energy potential (Semenov et al 2006) and are more desirable substrates for biodiesel (Vicente et al 2005) and biofuel (Zhao et al 2016) production. High erucic acid rapeseed (HEAR), currently the main feedstock for erucic acid used in industrial applications, contains about 50% of this fatty acid (Sanyal et al 2015). For improved technical utility and enhanced marketability of carinata oil, it is desirable to increase the C22:1 content and to simultaneously decrease the content of C20:1, polyunsaturated fatty acids (PUFA,linoleic [C18:2] and linolenic [C18:3] acids) and saturated fatty acids (palmitic [C16:0] and stearic [C18:0] acids).…”

Development of B. carinata with super-high erucic acid content through interspecific hybridization

et al. 2021

Key message Disomic alien chromosome addition Brassica carinata lines with super-high erucic acid content were developed through interspecific hybridization with B. juncea and characterized using molecular, cytological and biochemical techniques. Abstract Brassica carinata [A.] Braun (BBCC, 2n = 34) is a climate-resilient oilseed. Its seed oil is high in erucic acid (> 40%), rendering it well suited for the production of biofuel and other bio-based applications. To enhance the competitiveness of B. carinata with high erucic B. napus (HEAR), lines with super-high erucic acid content were developed through interspecific hybridization. To this end, a fad2B null allele from Brassica juncea (AABB, 2n = 36) was introgressed into B. carinata, resulting in a B. carinata fad2B mutant with erucic acid levels of over 50%. Subsequently, the FAE allele from B. rapa spp. yellow sarson (AA, 2n = 20) was transferred to the fad2B B. carinata line, yielding lines with erucic acid contents of up to 57.9%. Molecular analysis using the Brassica 90 K Illumina Infinium™ SNP genotyping array identified these lines as disomic alien chromosome addition lines, with two extra A08 chromosomes containing the BrFAE gene. The alien chromosomes from B. rapa were clearly distinguished by molecular cytogenetics in one of the addition lines. Analysis of microspore-derived offspring and hybrids from crosses with a CMS B. carinata line showed that the transfer rate of the A08 chromosome into male gametes was over 98%, resulting in almost completely stable transmission of an A08 chromosome copy into the progeny. The increase in erucic acid levels was accompanied by changes in the proportions of other fatty acids depending on the genetic changes that were introduced in the interspecific hybrids, providing valuable insights into erucic acid metabolism in Brassica.

Winged bean (Psophocarpus tetragonolobus (L.) (DC.) contains moderate to high fat in its seeds including palmitic acid (C18:0). Of those three sampling areas in Indonesia, the Sumateranese winged bean seeds contains 60%; which is important raw source of various oleochemical industries. Palmitoyl ACP is one among those enzyme involves in palmitic acid biosynthesis pathway from fatty acid synthase. Information about encoding genes of ACP enzyme which involves in palmitic acid biosynthesis pathway, therefore, becomes a prerequisite and became the aim of this study. Current study designed three different specific primer for palmitic acids namely: A. palmitoyl-ACP, B. KAS III, and C. acc D. each of them has the following nucleotide sequences: A. forward primer (F) 5'-GTC GTG CAT CGG GGA AGA A -3' and reverse (R) 5'-TCG CTC CAT TTA GGC TGC AA-3'. B. KAS III (F) 5'-TGC CAG ACA CCA TCA CAA ACT-3' and (R) 5'-TGA CGC CAG CGA TTA CAG C-3' and C. acc D (F) 5'-GGG CGT GAT GGA GTT TG-3' and (R) 5'-AGG TTG GCC TCG TTC TG-3' which were tested on three different genotypes the short pod winged beans, medium length pods and long pods ones on a PCR machine. The PCR resulted in amplicons
