Summary: This study identifies differences in the Scd gene between cold-adapted Crassostrea gigas and warm-adapted Crassostrea angulata. One single-nucleotide polymorphism (SNP) is found to potentially affect Scd transcription, leading to different levels of Scd expression in the two species. Additionally, differences in the expression of the positive transcription factor Srebp are also observed, which may contribute to the divergent phenotypic plasticity between the two species.

Summary: Researchers successfully identified a mutant allele in a fatty acid desaturase gene that is responsible for the high oleic acid content in certain cotton accessions. They also found that the missing amino acid residues in the mutant protein are not essential for enzyme activity but are necessary for proper subcellular targeting. This discovery will facilitate breeding programs to introduce the high oleic acid trait into other cotton varieties.

Summary: The fatty acid composition of olive oil, particularly high oleic and low linoleic acid content, has a significant impact on oil quality. Studies on 89 olive cultivars revealed that oleic and linoleic acid contents showed the highest degree of variability. Specific olive cultivars with extremely low and high linoleic acid contents were used to investigate the contribution of different fatty acid desaturases to the composition of the oil. The research suggests that gene expression levels and enzyme specificities are responsible for the variability of oleic/linoleic acid ratio in olive cultivars, providing valuable insights for olive breeding programs aimed at improving oil quality.

Summary: This study analyzes the soybean pangenome to identify fatty acid biosynthesis genes and their sequence diversity. It finds possible instances of gene missing in wild soybean and identifies missense variants in fatty acid biosynthesis genes. The frequency of these variants has been significantly reduced during domestication.

Summary: Gamma-linolenic acid (GLA) is an important fatty acid that has various applications in medicine and nutrition. Currently, GLA is primarily obtained from plant seeds, which is not suitable for industrial production. In this study, researchers successfully expressed GLA in yeast using gene engineering techniques and achieved a high production yield. This study opens up a new possibility for industrial-scale production of GLA.

Summary: The synthesis of hierarchical Low Silica X zeolite (LSX) with mesoporosity was achieved by using sodium dodecylbenzene sulfonate (SDBS) as a surfactant. The removal of SDBS resulted in the formation of mesoporous cavities and the development of a wider pore size distribution. The mesopomus Low Silica X zeolite (MLSX) exhibited higher catalytic activity in the deoxygenation of oleic acid, making it a potential catalyst for processing bulky molecules.

Summary: In this study, DBSA was utilized as an efficient catalyst for synthesizing oleic acid-based wax esters under solvent-free conditions at 40 degrees C. The optimal conditions yielded a 93.6% conversion rate of cetyl alcohol, with factors such as molar ratio, reaction temperature, and reaction time playing crucial roles. Water content was found to have an inhibitory effect on esterification, which decreased significantly with increasing temperature. DBSA-catalyzed low-temperature esterification proved to be an efficient method for producing liquid wax esters.

Summary: Rhodium is widely used in catalysis, but its adsorption by microorganisms is not well studied. In this work, waste P. pastoris and recombinant P. pastoris GS-R were used as novel adsorbents for Rh(III) adsorption, showing high adsorption capacity and selectivity. The study developed an environmentally-friendly strategy for recovering Rh(III) and other precious metals using P. pastoris.

Summary: The effects of two different fatty acid supplement blends on low- and high-producing dairy cows were evaluated, with findings showing varying responses based on milk production levels. Further research is needed to validate the observed differences in production responses to the fatty acid supplements for higher-yielding cows.
