Rapeseed contains glucosinolates, a toxic group of sulfur-containing glucosides, which play critical roles in defense against herbivores and microbes. However, the presence of glucosinolates in rapeseed reduces the value of the meal as feed for livestock. We performed association mapping of seed glucosinolate (GS) content using the 60K Brassica Infinium single nucleotide polymorphism (SNP) arra...

Lysophosphatidic acid acyltransferase acylates the sn-2 hydroxyl group of lysophosphatidic acid to form phosphatidic acid, a precursor to triacylglycerol. A cDNA encoding lysophosphatidic acid acyltransferase was isolated from developing seeds of meadowfoam (Limnanthes alba alba). The cDNA encodes a 281-amino acid protein with a molecular mass of 32 kD. The cDNA was expressed in developing seed...

The use of large-scale or genome-scale metabolic reconstructions for modeling and simulation of plant metabolism and integration of those models with large-scale omics and experimental flux data is becoming increasingly important in plant metabolic research. Here we report an updated version of bna572, a bottom-up reconstruction of oilseed rape (Brassica napus L.; Brassicaceae) developing seeds...

Seed yield and oil content are two important agricultural characteristics in oil crop breeding, and a lot of functional gene research is being concentrated on increasing these factors. In this study, by differential gene expression analyses between rapeseed lines (zy036 and 51070) which exhibit different levels of seed oil production, BnGRF2 (Brassica napus growth-regulating factor 2-like gene)...

Seed oil content is a key agronomical trait, while the control of carbon allocation into different seed storage compounds is still poorly understood and hard to manipulate. Using bna572, a large-scale model of cellular metabolism in developing embryos of rapeseed (Brassica napus) oilseeds, we present an in silico approach for the analysis of carbon allocation into seed storage products. Optimal...

Acetyl-coenzyme A carboxylase (ACCase) occurs in at least two forms in rapeseed (Brassica napus): a homomeric (HO) and presumably cytosolic isozyme and a heteromeric, plastidial isozyme. We investigated whether the HO-ACCase of Arabidopsis can be targeted to plastids of B. napus seeds. A chloroplast transit peptide and the napin promoter were fused to the Arabidopsis ACC1 gene and transformed i...

seed and oil yields, their components, and the relationships among trait performance were determined in 25genotypes of winter type oilseed rape (brassica napus l.). the experiment was carried out at the agricultural and natural resources research center of east azerbaijan, iran, in two consecutive growing seasons 2009-10 and 2010- 11. significant differences were observed in plant height, numbe...

proper irrigation scheduling, i.e. timely and adequate irrigation is an important prerequisite to profitable crop production. high temperatures along with soil moisture deficits are some of the main limiting factors for canola (b. napus l.) production in dry land cropping systems. these factors negatively affect the formation of pods during the flowering stage, resulting in decrease in seed yie...

Much of the commercially available lecithin is produced as a byproduct soybean oil extraction. However, there strong need for alternative feedstock due to presence allergens in soy lecithin. The objective present study was determine if oilseeds from Brassicaceae family such Brassica juncea, Sinapis alba, and napus represent viable source Total yields seed meals quantified. Composition extracted...
