Etiolation promotes protoplast transfection and genome editing efficiency.

Physiol Plant

November 2024

Department of Horticulture, College of Agricultural Life Science, Jeonbuk National University, Jeonju, Republic of Korea.

In plants, DNA-free genome editing using preassembled clustered regularly interspaced short palindromic repeats (CRISPR)-ribonucleoprotein (RNP) has the advantage of avoiding transgene integration and limiting off-target effects. The efficiency of this gene editing strategy can vary, so optimization of protoplast transfection conditions is necessary to achieve maximum yield. In this study, we examined the effects of etiolation, or increased exposure to darkness during cultivation, on the transfection efficiency of protoplasts from lettuce and Chinese cabbage.

This article reviews the literature concerning the largely forgotten tobamovirus gene products for which no functions have been ascribed. One of these gene products is the 54 kDa protein, representing the RNA-dependent RNA polymerase segment of the 183 kDa protein translated from the I-subgenomic mRNA, but which has been found only by in vitro translation and not . The other is a collection of small proteins, expressed from alternative reading frames (likely from internal ribosome entry sites) in either or both the gene or the gene.

Background: This study aimed to optimize the coating process of Omega-3 fatty acid (OM3-FA) mini soft capsules containing the active pharmaceutical ingredients (APIs) pitavastatin and ezetimibe using near-infrared (NIR) spectroscopy for in-process monitoring. Cardiovascular disease treatments benefit from combining OM3-FA with lipid-lowering agents, but formulating such combinations in mini soft capsules presents challenges in maintaining stability and mechanical integrity.

Methods: The coating process was developed using a pan coater and real-time NIR monitoring to ensure uniformity and quality.

Microbial plant biostimulants offer a promising, sustainable solution for enhancing plant growth and resilience, particularly under abiotic stress conditions such as drought, salinity, extreme temperatures, and heavy metal toxicity. These biostimulants, including plant growth-promoting rhizobacteria, mycorrhizal fungi, and nitrogen-fixing bacteria, enhance plant tolerance through mechanisms such as phytohormone production, nutrient solubilization, osmotic adjustment, and antioxidant enzyme activation. Advances in genomics, metagenomics, transcriptomics, and proteomics have significantly expanded our understanding of plant-microbe molecular communication in the rhizosphere, revealing mechanisms underlying these interactions that promote stress resilience.

Lumpy skin disease (LSD), caused by the LSD virus (LSDV), a dsDNA virus of the genus Capripoxvirus, represents a significant cross-border infectious threat, particularly impacting cattle and water buffaloes through transmission by blood-feeding insects. Traditionally endemic to Southern Africa, LSD has rapidly spread over the past decade through the Middle East to Eastern Europe and China, reaching Korea in October 2023. This outbreak prompted a nationwide vaccination campaign, addressing both the disease's severe economic impact and its status as a notifiable disease under the World Organisation for Animal Health.

Augmenting Rice Defenses: Exogenous Calcium Elevates GABA Levels Against WBPH Infestation.

Antioxidants (Basel)

October 2024

Department of Applied Biosciences, Graduate School, Kyungpook National University, Daegu 41566, Republic of Korea.

This study investigates the impact of exogenous calcium and gamma-aminobutyric acid (GABA) supplementation on rice growth and stress tolerance under white-backed planthopper (WBPH) infestation. We evaluated several phenotypic traits, including shoot/root length, leaf width, tiller number, panicle length, and relative water content, alongside physiological markers such as oxidative stress indicators, antioxidant enzymes activities, hormonal levels, and amino acids biosynthesis. Our results indicate that WBPH stress significantly reduces growth parameters but calcium and GABA supplementation markedly enhance shoot length (by 26% and 36%) and root length (by 38% and 64%), respectively, compared to WBPH-infested plants.

Mycotoxins occur singly or as co-contaminants and are primarily present in carbohydrate-rich foods such as cereals and cereal-based products. To effectively monitor mycotoxin co-contamination in cereals and cereal-based products, the simultaneous analysis of mycotoxins and their derivatives is required. Therefore, we coupled cleanup with LC-MS/MS for the rapid and robust quantitation of 35 analytes in wheat samples, including ergot alkaloids (EAs), which are rarely included in such analyses.

Expensive fetal bovine serum (FBS) is a major obstacle to the production of cultivated meat. However, because FBS substitutes do not sufficiently induce cell proliferation, a good alternative is to reduce the amount of FBS and use ingestible additives to promote cell proliferation. In this study, Grifola frondosa extract (GFE) was used to investigate its potential as an additive to promote myogenesis of bovine muscle satellite cells from Hanwoo cattle under low serum conditions (10 % FBS).

Echocardiography is the gold standard of diagnosis and evaluation of patent ductus arteriosus (PDA), a common condition among preterm infants that can cause hemodynamic abnormalities and increased mortality rates, but this technique requires a skilled specialist and is not always available. Meanwhile, chest X-ray (CXR) imaging is also known to exhibit signs of PDA and is a routine imaging modality in neonatal intensive care units. In this study, we aim to find and objectively define CXR image features that are associated with PDA by training and visually analyzing a deep learning model.

Vet Sci

November 2024

Department of Avian Diseases, College of Veterinary Medicine and Center for Avian Disease, Jeonbuk National University, Iksan 54596, Republic of Korea.

The duck Tembusu virus (DTMUV), an emerging flavivirus, has led to severe neurological disorders and substantial economic losses in the duck industry throughout Asia. Considering South Korea's increasing duck production and its strategic location along the East Asian-Australasian Flyway, this study aimed to assess the presence of DTMUV in South Korea to evaluate potential risks to the poultry industry. We performed a comprehensive serological survey of 1796 serum samples from broiler and breeder ducks collected between 2011 and 2023, alongside molecular detection tests on 51 duck flocks exhibiting suspected clinical signs of DTMUV infection.

Nanomaterials (Basel)

November 2024

Department of Chemistry, College of Natural Sciences, Yeungnam University, 280 Daehak-Ro, Gyeongsan 38541, Republic of Korea.

Fabricating photoanodes with a strong light-scattering effect can improve the photoconversion efficiency of dye-sensitized solar cells (DSSCs). In this work, a facile microwave hydrothermal process was developed to prepare Au@TiO core-shell nanostructures, and then the Au core was removed by etching, resulting in hollow TiO. Morphological characterizations such as field emission scanning and transmission electron microscopy measurements have been used for the successful formation of core-shell and hollow TiO nanostructures.

The application of cell sheet technology for wound healing preserves dense cell tissue and the natural extracellular matrix (ECM), contributing to disease prevention. Despite the effectiveness of autologous and allograft cell sheets for wound healing, conventional cell sheets, although stable, may experience necrosis in their middle layers due to a lack of nutrients or oxygen. To address these issues, a novel approach is proposed to create cell sheets using mechanical and electrical stimulation.

Whey protein from bovine milk is highly valued in the food and pharmaceutical industries because of its high protein content and abundance of essential amino acids. The relationship between whey protein and the β-lactoglobulin (BLG) gene has been extensively discussed because BLG is the most abundant whey protein, making up approximately 50 % of the total whey protein in bovine milk. In recent years, researchers have been interested in this gene because of its critical role in healthy milk production, and any genetic polymorphism in this gene may deteriorate the milk quality.
