Introduction. Oilseed rape (Brassica napus L.) is one of the most important oil crops worldwide and provides high‐quality edible vegetable oil for human edibility and processing quality of rapeseed oil are mainly determined by the fatty acid composition of the seeds, particularly the proportions of the three major unsaturated fatty acids: oleic acid (C), linoleic acid Cited by: 2.

The two major storage proteins identified in Brassica napus (canola) were isolated and studied for their molecular composition, structural characteristics and the responses of structural features to the changes in pH and temperature. Cruciferin, a complex of six monomers, has a predominantly β-sheet-containing secondary structure.
This protein showed low pH unstable tertiary structure, and Cited by: Genome-wide association study of heat stress-tolerance traits in spring-type Brassica napus L. under controlled conditions L.

However, little is known about the transcriptomic changes that occur in the industrial oilseed crop, rapeseed (Brassica napus), in response to abiotic stress.

Canola (Brassica napus L.) is the member of the Brassicaceae family (syn.

Low-molecular mass (10 kD) cytosolic acyl-coenzyme A-binding protein (ACBP) has a substantial influence over fatty acid composition in oilseeds, possibly via an effect on the partitioning of acyl groups between elongation and desaturation usly, we demonstrated that the expression of a Brassica napus ACBP (BnACBP) complementary DNA in the developing Cited by: Oilseed rape (Brassica napus L.) is an allotetraploid species with 2n = 38 chromosomes and two genomes (AA derived from B.

Analysis of Self-Compatible Mutant BrassicaStrains. Two self-compatible (SC) mutant Brassica strains that exhibit defects in the structure or expression of SLG were used in this study: (a) Brassica campestris (syn.

Although the difference in seed oil content between soybean (~ 20%) and rapeseed (~ 40%) exists, little is known about its underlying molecular mechanism. An integrated omics analysis was performed in soybean, rapeseed, Cited by: 1.
Brassica napus seed is a lipid storage organ containing approximately 40% oil, while its leaves contain many kinds of lipids for many biological roles, but the overall amounts are less than in seeds.
Thus, lipid biosynthesis in the developing seeds and the leaves is strictly regulated which results the final difference of lipids. However, there are few reports about the molecular mechanism Cited by: Rapeseed (Brassica napus) is an important oil seed crop, providing more than 13% of the world’s supply of edible oils.
An in-depth knowledge of the gene network involved in biosynthesis and accumulation of seed oil is critical for the improvement of B. napus. Using available genomic and transcriptomic resources, we identified 1, acyl-lipid metabolism (ALM) genes that are distributed over Cited by: In Brassica napus, oleosins are expressed at high levels in the seed during the latter stages of embryo development.

Plants require sunlight, water, CO2, and essential nutrients to drive photosynthesis and fulfill their life cycle. The photosynthetic apparatus resides in chloroplasts and fundamentally relies on transition metals as catalysts and cofactors.
Accordingly, chloroplasts are particularly rich in iron (Fe), manganese (Mn), and copper (Cu). Owing to their redox properties, those metals need to be. MicroRNAs (miRNAs) are noncoding RNAs that play an important role in the regulation of the genetic expression in animals and plants by targeting mRNAs for cleavage or translational repression.
Several miRNAs regulate the plant development, the metabolism, and the responses to biotic and abiotic stresses.

Brassica napus L. is an important oilseed and fodder crop with significant heterosis for seed yield and other agronomic traits, but very little is known about the molecular basis of heterosis. As an initial step towards understanding the molecular events associated with this phenomenon, a molecular functional map of rapeseed was constructed using differentially expressed genes in hybrid.Enter search terms.
