Sex pheromone evolution is associated with differential regulation of the same desaturase gene in two genera of leafroller moths. [PDF]

open access: yesPLoS Genetics, 2012
Chemical signals are prevalent in sexual communication systems. Mate recognition has been extensively studied within the Lepidoptera, where the production and recognition of species-specific sex pheromone signals are typically the defining character ...

Palmitoleic and Dihomo-γ-Linolenic Acids Are Positively Associated With Abdominal Obesity and Increased Metabolic Risk in Children

open access: yesFrontiers in Pediatrics, 2021
Background: The impact of abdominal obesity (AO) on plasma fatty acid changes and cardiometabolic risk in children who are obese and overweight has rarely been investigated.

Conversion of dihydroceramide into ceramide: involvement of a desaturase [PDF]

open access: yesBiochemical Journal, 1997
Ceramide has been suggested to be a potent bioactive lipid involved in cell growth, differentiation and apoptosis. Its precursor, dihydroceramide, does not affect these processes. The truncated dihydroceramide analogues N-hexanoyl-[4,5-3H]-D-erythro-sphinganine and N-[1-14C]-hexanoyl-D-erythro-sphinganine were used to study the conversion of ...

The dihydroceramide desaturase is not essential for cell viability in Schizosaccharomyces pombe

open access: yes, 2003
Recent studies have identified a new family of desaturase-like polypeptide sequences in many higher eukaryotes. Functional characterisation of one member of this family, from Schizosaccharomyces pombe, revealed the enzyme to be a sphingolipid desaturase.

Identification of a Δ11 desaturase from the arbuscular mycorrhizal fungus Rhizophagus irregularis

open access: yes, 2020
Arbuscular mycorrhizal fungi are oleaginous organisms and the most abundant fatty acyl moiety usually found in their lipids is palmitvaccenic acid (16:1Δ11cis). However, it is not known how this uncommon fatty acid species is made.

The Desaturase Gene Family is Crucially Required for Fatty Acid Metabolism and Survival of the Brown Planthopper, Nilaparvata lugens [PDF]

open access: yes, 2019
Desaturases are essentially required for unsaturated fatty acid (UFA) biosynthesis. We identified 10 genes encoding putative desaturases in the transcriptome database of the brown planthopper (BPH), Nilaparvata lugens.

Functional identification of a fatty acid Δ5 desaturase gene from Caenorhabditis elegans

open access: yes, 1998
We have identified a cDNA from the nematode worm Caenorhabditis elegans that encodes a fatty acid Δ5 desaturase. Saccharomyces cerevisiae expressing the full-length cDNA was able to convert di-homo-γ-linolenic acid to arachidonic acid, thus confirming Δ5

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Biosynthesis of Polyunsaturated Fatty Acids in the Oleaginous Marine Diatom Fistulifera sp. Strain JPCC DA0580

open access: yesMarine Drugs, 2013
Studies of polyunsaturated fatty acid (PUFA) biosynthesis in microalgae are of great importance for many reasons, including the production of biofuel and variable omega 3-long chain PUFAs. The elucidation of the PUFA biosynthesis pathway is necessary for

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

open access: yesAnimal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.
