Light enables a very high efficiency of carbon storage in developing embryos of rapeseed.
The conversion of photosynthate to seed storage reserves is crucial to plant fitness and agricultural production, yet quantitative information about the efficiency of this process is lacking. To measure metabolic efficiency in developing seeds, rapeseed (Brassica napus) embryos were cultured in media in which all carbon sources were [U-14C]-labeled and their conversion into CO2, oil, protein, a...
متن کاملOil, erucic acid, and glucosinolate contents in winter hardy rapeseed germplasms
The US industry uses :18 million kg of high erucic acid oil annually, mostly from imports. Therefore, a large overall market potential exists for development of annually renewable domestic sources of erucic acid. The present research was conducted to characterize the winter hardy rapeseed germplasm for oil, erucic acid, and glucosinolate contents for use in breeding programs to develop commerci...
متن کاملDietary low-glucosinolate rapeseed meal affects thyroid status and nutrient utilization in rainbow trout (Oncorhynchus mykiss).
Two rapeseed (Brassica napus) meals, RM1 and RM2, with two levels of glucosinolates (GLS; 5 and 41 mumol/g DM respectively) were incorporated at the levels of 300 and 500 g/kg of the diets of juvenile rainbow trout (Oncorhynchus mykiss) in replacement of fish meal, and compared with a fish-meal-based diet. A decrease in the digestibility of the DM, protein, gross energy and P was observed with ...
متن کاملSucrose uptake by developing soybean cotyledons.
Sucrose uptake by excised developing soybean cotyledons shows a biphasic dependence on sucrose concentration. At concentrations less than about 50 millimolar external sucrose, uptake can be described as a carrier-mediated process, with a K(m) of 8 millimolar. At higher external sucrose concentrations, a linear dependence becomes apparent, which suggests the participation of a nonsaturable compo...
متن کاملUptake and tissue-specific distribution of selected polychlorinated biphenyls in developing chicken embryos.
Fertilized chicken eggs were injected with high doses of individual polychlorinated biphenyl (PCB) congeners (0.5 microg of PCB 77, 9.8 microg of PCB 153, or 10.9 microg of PCB 180) before incubation to investigate the structure-specific uptake of these compounds by the embryo and their accumulation in brain and liver tissue. In accordance with earlier publications, a gradual uptake and accumul...
