AI Article Synopsis
- - The study examined how preharvest methyl jasmonate (MeJA) application affects raspberry quality during a 10-day cold storage, focusing on firmness, decay, and weight loss.
- - MeJA treatment preserved higher levels of beneficial compounds like soluble solids, ascorbic acid, anthocyanins, and flavonoids, while altering cell wall components and enzyme activities.
- - Overall, using MeJA can improve the storage quality of raspberries by enhancing firmness, maintaining key nutrients, and boosting phenolic metabolism while minimizing cell wall breakdown.
Article Abstract
The effects of preharvest methyl jasmonate (MeJA) spray application on the physicochemical quality, metabolism of phenolics, and cell wall components in raspberries were investigated during a 10-day cold storage period. MeJA spray reduced firmness loss, decay incidence, and weight loss, while maintained higher levels of soluble solids content, ascorbic acid, anthocyanins and flavonoids in raspberries. Furthermore, MeJA application resulted in increased total pectin and protopectin levels, as well as lowered water-soluble pectin, and activities of pectin methyl esterase, polygalacturonase and cellulase enzymes. Additionally, MeJA treatment upregulated the phenylpropanoid pathway, leading to higher endogenous phenolics and activities of phenylalanine-ammonia lyase and shikimate dehydrogenase. In conclusion, preharvest MeJA spray application could be adopted to enhance the storage potential of cold-stored raspberries for 10 days by maintaining higher firmness, assuring better physicochemical quality, and increasing phenolic metabolism, while reducing cell wall hydrolysis.

Few studies have explored the impact of blue light-emitting diode (BL) irradiation combined with different storage temperatures on antioxidant defense and cell wall metabolic activities related to the quality deterioration of postharvest strawberries. This study investigates the effects of BL exposure as a non-chemical preservation strategy to improve the postharvest quality of strawberries stored at 22 °C and 8 °C. Over a 10-day storage period, BL irradiation significantly reduced respiratory and ethylene production rates, while preserving fruit firmness and increasing the contents of soluble sugar and total phenol at both temperatures.

Plant genetic engineering methods are critical for food security and biofuel production and to enable molecular farming. Here, we elucidated how polymeric high aspect ratio nanocarriers can enable DNA delivery to plants and transient expression. We demonstrated that a nanocarrier with 20 nm width, 80 nm length, and a polymer-to-DNA ratio of N/P = 3.

Background: Tobacco brown spot (TBS) caused by Alternaria alternata is one of the most common diseases of tobacco in China, resulting in large loss in yield and quality. Demethylation inhibitors (DMIs) such as tebuconazole are commonly used pesticides to control TBS. However, their control effect has shown a downward trend in recent years.

Background: Dental root canal failure is a disease caused by gram-positive bacteria, Enterococcus faecalis. The disease is caused by the bacterial cell wall consisting of a peptidoglycan layer that protects the bacteria from internal osmotic pressure. Peptidoglycan biosynthesis includes many enzymes, such as MurA, Penicillin-binding protein (PBP), and SrtA.

The worldwide spread of antibiotic resistance is considered to be one of the major health threats to society. While developing new antibiotics is crucial, there is also a strong need for next-generation analytical methods for studying the physiological state of live bacteria in heterogeneous populations and their response to environmental stress. Here we report a single-cell high-throughput method to monitor changes in the bacterial cell envelope in response to stress based on ratiometric flow cytometry.
