Patatin-related phospholipase pPLAIIIβ-induced changes in lipid metabolism alter cellulose content and cell elongation in Arabidopsis.
The release of fatty acids from membrane lipids has been implicated in various plant processes, and the patatin-related phospholipases (pPLAs) constitute a major enzyme family that catalyzes fatty acid release. The Arabidopsis thaliana pPLA family has 10 members that are classified into three groups. Group 3 pPLAIII has four members but lacks the canonical lipase/esterase consensus catalytic se...
متن کاملOverexpression of patatin-related phospholipase AIIIβ altered the content and composition of sphingolipids in Arabidopsis
In plants, fatty acids are primarily synthesized in plastids and then transported to the endoplasmic reticulum (ER) for synthesis of most of the complex membrane lipids, including glycerolipids and sphingolipids. The first step of sphingolipid synthesis, which uses a fatty acid and a serine as substrates, is critical for sphingolipid homeostasis; its disruption leads to an altered plant growth....
متن کاملPatatin-related phospholipase pPLAIIIδ increases seed oil content with long-chain fatty acids in Arabidopsis.
The release of fatty acids from membrane lipids has been implicated in various metabolic and physiological processes, but in many cases, the enzymes involved and their functions in plants remain unclear. Patatin-related phospholipase As (pPLAs) constitute a major family of acyl-hydrolyzing enzymes in plants. Here, we show that pPLAIIIδ promotes the production of triacylglycerols with 20- and 22...
متن کاملChanges in Biochemical Parameters Related to Lipid Metabolism Following Lithium Treatment in Rat
Lithium is widely used in medicine as an anti-depressive drug. In spite of abundant literature, questions on the side effects of lithium ions are far from being answered. In this study, the effects of lithium on biochemical parameters related to lipid metabolism were investigated. Male Wistar rats were treated with different doses of lithium for a period of up to 60 days. Blood samples were col...
متن کاملChanges in Biochemical Parameters Related to Lipid Metabolism Following Titanium Treatment in Rat
Titanium salts are widely used in pharmacy and industry as intensely white permanent pigment with good covering power in paints , paper , toothpaste , plastics and food dye s. This ion is a redox-active transition metal and may cause oxidative damages to lipids, proteins and DNA molecules. In spite of abundant literature, questions about the side effects of titanium ions...
