palmitoleic/brassica

cis-Vaccenic acid or cis-11-octadecenoic acid, a C18:1 (n-7) isomer of oleic acid (C18:1 (n-9)) has been found in several oilseeds. It is synthesized from palmitic acid (C16:0) via production of C16:1 (n-7) by a Delta9 desaturase and elongation by an elongase giving C18:1 (n-7). In this study, the

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

Treatment of rape seedlings with increasing CdCl2 concentrations in the culture medium resulted in a cadmium accumulation within plant tissues, which increased with external metal dose; such accumulation was more important in roots than in leaves. Biomass production was severely inhibited, even at

Brassica napus leaves developed at low temperature display rapid in situ desaturation of monogalactosyldiacylglycerol (MGDG) fatty acids leading to the production of hexadecatrienoic/linolenic acid. This was shown by radioactivity-tracer experiments to occur via a sequence of desaturations

Brassica juncea plants transformed with the Arabidopsis ADS1 gene, which encodes a plant homologue of the mammalian and yeast acyl-CoA Delta9 desaturases and the cyanobateria acyl-lipid Delta9 desaturase, were found to have a statistically significant decrease in the level of saturated fatty acids

A cDNA encoding a novel isoform of acyl-CoA synthetase (ACS6) was isolated from embryos of oilseed rape. Homology searches show it is most closely related to ACS4 from rat and human brain rather than the other oilseed rape ACSs. The ACS6 is strongly expressed in embryos and flowers, tissues of

Salinity stress is known to modify the plasma membrane lipid and protein composition of plant cells. In this work, we determined the effects of salt stress on the lipid composition of broccoli root plasma membrane vesicles and investigated how these changes could affect water transport via
