Benzyl Amino Purine and Gibberellic Acid Coupled to Nitrogen-Limited Stress Induce Fatty Acids, Biomass Accumulation, and Gene Expression in Scenedesmus Obliquus

Transfer ribonucleic acid from Scenedesmus obliquus D3.

Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...

Response of laying hens to supplementation with various fatty acids when fed diets inadequate in protein and sulphur amino acids

The Association of Omentin Gene Expression in Visceral and Subcutaneous Adipose Tissues with Plasma Fatty Acids Profile and Dietary Fatty Acids

Introduction: Omentin, an adipokine, with anti-inflammatory effects reduces insulin resistance, and can hence, play an important role in prevention of cardiovascular disease and diabetes. The present study aimed to investigate the association of plasma and dietary fatty acids with gene expression of omentin in visceral and subcutaneous adipose tissues. Materials and Methods: Visceral and subcut...

Nitrogen deficiency in Arabidopsis affects galactolipid composition and gene expression and results in accumulation of fatty acid phytyl esters.

Nitrogen is an essential nutrient for plants because it represents a major constituent of numerous cellular compounds, including proteins, amino acids, nucleic acids and lipids. While N deprivation is known to have severe consequences for primary carbon metabolism, the effect on chloroplast lipid metabolism has not been analysed in higher plants. Nitrogen limitation in Arabidopsis led to a decr...

Superior triacylglycerol (TAG) accumulation in starchless mutants of Scenedesmus obliquus: (I) mutant generation and characterization

BACKGROUND Microalgae are a promising platform for producing neutral lipids, to be used in the application for biofuels or commodities in the feed and food industry. A very promising candidate is the oleaginous green microalga Scenedesmus obliquus, because it accumulates up to 45% w/w triacylglycerol (TAG) under nitrogen starvation. Under these conditions, starch is accumulated as well. Starch ...
