Summary: High temperatures have a negative impact on the growth and productivity of Gracilariopsis lemaneiformis. In this study, the researchers discovered that patatin-like phospholipase A (pPLA) plays a crucial role in the stress response of G. lemaneiformis. By inhibiting the activity of pPLA, the sensitivity of G. lemaneiformis to heat stress increased, leading to decreased biomass and photosystem II activity. Moreover, the inhibition of pPLA resulted in alterations in lipid metabolism and the biosynthesis of jasmonic acid (JA). This research provides new insights into the heat stress adaptation mechanism of G. lemaneiformis.

Summary: Inclusion of dietary vegetable sources rich in UFA in sheep diets helps improve cheese composition by decreasing saturated FA content and increasing polyunsaturated FA content. However, the effects on milk yield, milk fat percentage, and milk protein percentage are not significant, with significant heterogeneity present.

Summary: The temperature tolerance of Gracilariopsis lemaneiformis cultivated for nearly 35 years was compared to its wild-type counterpart. The cultivated strains showed lower performance in photosynthesis and respiration at low temperatures and better adaptation at high temperatures. Additionally, the cultivated strains exhibited lower oxidative stress and higher heat shock protein response at high temperatures.

Summary: Research indicates that diets rich in fats and carbohydrates exacerbate non-alcoholic fatty liver disease (NAFLD) and cause mitochondrial dysfunction. It is suggested that high-fat and high-carbohydrate diets may affect mitochondrial oxidative remodeling differently. The high fructose-driven 'lipogenic' environment could induce hepatic oxidative function, potentially influencing the severity of hepatic insulin resistance.

Summary: Rice cultivated in the tropics faces high temperature stress, which can impact its growth and survival. This study aimed to understand the response of rice to high temperature stress by analyzing photosystem II efficiency, membrane stability, and fatty acid composition. The results showed that certain rice genotypes exhibited high heat tolerance, with lower increases in electrolyte leakage and malondialdehyde levels, and stable photosystem II efficiency. These heat-tolerant genotypes also showed changes in the fatty acid composition, with a reduction in unsaturated fatty acids and an increase in long-chain fatty acids. These fatty acid changes may contribute to enhanced photosynthetic performance and heat tolerance in rice.

Summary: This study analyzed the molecular species of TAG in human milk fat and its changes during lactation using UPLC-Q-TOF-MS. The results showed that the changes in TAG mainly occurred in the early stages of lactation, and the TAG profile became stable after 200 days of lactation. Odd chain fatty acids may be important markers for identifying different lactation stages.

Summary: Plants convert carbohydrates into energy-dense lipids through photosynthesis, making plant oils an economically and sustainably attractive feedstock for biofuels and value-added bioproducts. Various strategies have been developed to enhance lipid accumulation and produce specialty lipids with increased uses and value. Successful metabolic engineering involves expression of lipogenic factors from other sources or with specialized functionality.

Summary: A study found that phosphorus deficiency increases seed oil content and alters fatty acid composition of Camelina seeds, but greatly reduces seed production. This suggests that achieving a high yield and quality of Camelina seed oil is closely linked to the phosphorus status of the soil.
