The effect of activation ("aging") of potato tuber slices on their phospholipid metabolism was investigated. Aged slices were incubated with (14)C labeled choline, ethanolamine, methionine, serine, and acetate. In all cases, the incorporation of radioactivity into the lipid fraction increased with
Freshly cut slices of potato tuber show an extensive loss of membrane lipid components which may be as great as 35% for phospholipids and 30% for glycolipids, in less than 15 minutes at 3 C. Phosphatidyl-choline, phosphatidyl-ethanolamine and mono- and di-galactosyl diglycerides comprise the bulk of
A method for rapid isolation of glyco- and phospholipids from potato leaves by a two-fold separation in a thin layer of silica gel is described. Using gas-liquid chromatography, the fatty acid compositions of monogalactosyldiglyceride, digalactosyldiglyceride, sulfolipid, phosphatidyl choline,
A Gram-stain-negative, non-motile, non-spore-forming bacterium, designated MLS-26-JM13-11T, was isolated from potato stems, collected in Guyuan County, Hebei Province, China. Strain MLS-26-JM13-11T could grow at 10-39 °C (optimum, 30 °C), pH 6.0-9.0 (optimum, pH 7.2) and in the presence of 0-4.0 %
Four Canadian varieties of potatoes were examined for their lipid composition. Lipids, extracted with chloroformmethanol, were shown by TLC and column chromatography to consist of 16.5% neutral lipids, 45.5% phospholipids and 38.1% glycolipids. Among the phospholipids and glycolipids, phosphatidyl
The phosphatidyl ethanolamine-binding proteins (PEBPs) function primarily in regulating flowering in plants. Here, we report a genome-wide identification of PEBPs and functional characterization of a novel FLOWERING LOCUS T homolog (NtFT5) in tobacco, Nicotiana tabacum. Seven new PEBPs were
Plants are known to synthesize ethanolamine (Etn) moieties by decarboxylation of free serine (Ser), but there is also some evidence for phosphatidyl-Ser (Ptd-Ser) decarboxylation. Database searches identified diverse plant cDNAs and an Arabidopsis gene encoding 50-kD proteins homologous to yeast
Geographically the prevalence of duodenal ulceration is related to the staple foods in the diet in regions of developing countries where the diet is stable. It is higher in regions where the diet is based on milled rice, refined wheat or maize, yams, cassava, sweet potato, or green bananas, and is
The prevalence of duodenal ulceration in regions of developing countries with a stable diet is related to the staple food(s) in that diet. A higher prevalence occurs in areas where the diet is principally milled rice, refined wheat or maize, yams, cassava, sweet potato or green bananas, and a lower
