The subcellular location of diacylglycerol acyltransferase (EC 2.3.1.20) in spinach leaves (Spinacia oleracea L. cv. Longstanding Bloomsdale) was determined after sucrose-gradient centrifugation of tissue homogenates. Enzyme activity was associated primarily with gradient fractions containing oil
Molecular species and fatty acid distribution of triacylglycerol (TG) accumulated in spinach (Spinacia oleracea L.) leaves fumigated with ozone (0.5 microliter per liter) were compared with those of monogalactosyldiacylglycerol (MGDG). Analysis of positional distribution of the fatty acids in MGDG
Recent pressures to obtain energy from plant biomass have encouraged new metabolic engineering strategies that focus on accumulating lipids in vegetative tissues at the expense of lignin, cellulose and/or carbohydrates. There are at least three important factors that support this rationale. (i)
When the upper leaf surface of spinach (Spinacia oleracea L.) plants was treated with [1-(14)C]acetate and grown for 2 days, (14)C was effectively incorporated into acyl moieties of leaf lipids in ratios approximately their composition by mass. Fumigation of the plants with ozone (0.5 microliter per
The phytochemical study of hexane, chloroform and methanol extracts from leaves of Psychotria viridis resulted in the identification of: the pentacyclic triterpenes, ursolic and oleanolic acid; the steroids, 24-methylene-cycloartanol, stigmasterol and β-sitosterol; the glycosylated steroids
Starch and lipids represent two major forms of carbon and energy storage in plants and play central roles in diverse cellular processes. However, whether and how starch and lipid metabolic pathways interact to regulate metabolism and growth are poorly understood. Here, we show that lipids can
Lipid remodeling plays an important role in the adaptation of plants to environmental factors, but the mechanism by which lipid remodeling mediates salt stress response remains unclear. In this study, we compared the root and leaf lipidome profiles of salt-tolerant and salt-sensitive sweet potato
When applied in liquid paraffin to the upper surface of expanding spinach leaves, [1-14C]palmitic acid was efficiently and exclusively incorporated into the sn-1 position of cellular glycerolipids, principally phosphatidylcholine and triacylglycerol. A slow transfer of fatty acids from
High biomass crops have recently attracted significant attention as an alternative platform for the renewable production of high energy storage lipids such as triacylglycerol (TAG). While TAG typically accumulates in seeds as storage compounds fuelling subsequent germination, levels in vegetative
Environmental stresses cause membrane damage in terrestrial plants. Studies on the lipids obtained from these plants are required to understand their adaptation to climate change. Recently, a number of plant leaf lipidomic studies converged on the topic of chloroplastic glycerolipid remodeling and
The seeds of many nondomesticated plant species synthesize oils containing high amounts of a single unusual fatty acid, many of which have potential usage in industry. Despite the identification of enzymes for unusual oxidized fatty acid synthesis, the production of these fatty acids in engineered
BACKGROUND
Traditional plant treatment for diabetes has shown a surging interest in the last few decades. Therefore, the purpose of this study was to assess the hypoglycemic effect of the aqueous extract of C. papaya leaves in diabetic rats. Several studies have reported that some parts of the C.
The present studies were conducted to investigate the changes in lipid and fatty acid composition during the earliest stages of somatic embryogenesis in leaf tissues of the Cichorium hybrid '474'. The presence of glycerol in the culture medium during the induction step allowed to separate two phases
We manufactured a new fermented tea by tea-rolling processing of third-crop green tea (Camellia sinensis) leaves and loquat (Eriobotrya japonica) leaves. The mixed fermented tea extract inhibited pancreatic lipase activity in vitro, and effectively suppressed postprandial hypertriacylglycerolemia in
Prevention of postprandial hypertriglyceridemia is an important consideration for reducing the risk of developing cardiovascular disease. While blueberry fruits have been reported to ameliorate lipid metabolism in humans, there are only few research reports on the effects of blueberry leaves (BL).
