A seed-specific DNA-binding with One Finger transcription factor, RPBF, positively regulates galactinol synthase to maintain seed vigour in rice.

Seed vigour and longevity are intricate yet indispensable physiological traits for agricultural crops, as they play a crucial role in facilitating the successful emergence of seedlings and exert a substantial influence on crop productivity. Transcriptional regulation plays an important role in seed development, maturation, and desiccation tolerance, which are important attributes for seed vigour and longevity. Here, we have investigated the regulatory role of the seed-specific DNA-binding with One Finger (DOF) transcription factor and the rice prolamin box binding factor (RPBF) in seed vigour.

The prolonged duration of conventional antibiotic therapy warrants innovative approaches to shorten treatment courses. In response to challenges, the study explores potential of Ajoene, a naturally occurring garlic extract-derived compound, for potential TB treatment.

Synthesis of dumbbell-like heteronanostructures encapsulated in ferritin protein: Towards multifunctional protein based opto-magnetic nanomaterials for biomedical theranostic.

Dumbbell-like hetero nanostructures based on gold and iron oxides is a promising material for biomedical applications, useful as versatile theranostic agents due the synergistic effect of their optical and magnetic properties. However, achieving precise control on their morphology, size dispersion, colloidal stability, biocompatibility and cell targeting remains as a current challenge. In this study, we address this challenge by employing biomimetic routes, using ferritin protein nanocages as template for these nanoparticles' synthesis.

The arginine/ornithine binding protein ArgT plays an essential role in / to prevent intracellular killing and contribute to chronic persistence in the host.

Blood-Based Biomarkers in Alzheimer's Disease: Advancing Non-Invasive Diagnostics and Prognostics.

Alzheimer's disease (AD), the most prevalent form of dementia, is expected to rise dramatically in incidence due to the global population aging. Traditional diagnostic approaches, such as cerebrospinal fluid analysis and positron emission tomography, are expensive and invasive, limiting their routine clinical use. Recent advances in blood-based biomarkers, including amyloid-beta, phosphorylated tau, and neurofilament light, offer promising non-invasive alternatives for early AD detection and disease monitoring.

Bisphenol F-induced precocious genesis of aggressive neurobehavioral response is associated with heightened monoamine oxidase activity and neurodegeneration in zebrafish brain.

The production and use of plastics and plastics products has increased dramatically in recent decades. Moreover, their unprotected disposal into ambient life sustaining environment poses a significant health risk. Bisphenol F (BPF) an alternative to bisphenol A (BPA) has been extensively employed for making of plastics.

Dissecting the Conformational Heterogeneity of Stem-Loop Substructures of the Fifth Element in the 5'-Untranslated Region of SARS-CoV-2.

Throughout the family of coronaviruses, structured RNA elements within the 5' region of the genome are highly conserved. The fifth stem-loop element from SARS-CoV-2 (5_SL5) represents an example of an RNA structural element, repeatedly occurring in coronaviruses. It contains a conserved, repetitive fold within its substructures SL5a and SL5b.

Promising and challenging phytochemicals targeting LC3 mediated autophagy signaling in cancer therapy.

Background: Phytochemicals possess a wide range of anti-tumor properties, including the modulation of autophagy and regulation of programmed cell death. Autophagy is a critical process in cellular homeostasis and its dysregulation is associated with several pathological conditions, such as cancer, neurodegenerative diseases, and diabetes. In cancer, autophagy plays a dual role by either promoting tumor growth or suppressing it, depending on the cellular context.

Leveraging trait and QTL covariates to improve genomic prediction of resistance to Fusarium head blight in Central European winter wheat.

Fusarium head blight (FHB) is a devastating disease of wheat, causing yield losses, reduced grain quality, and mycotoxin contamination. Breeding can mitigate the severity of FHB epidemics, especially with genomics-assisted methods. The mechanisms underlying resistance to FHB in wheat have been extensively studied, including phenological traits and genome-wide markers associated with FHB severity.

Spray inoculation and image analysis-based quantification of powdery mildew disease severity on pea leaves.

Pea () is an important agricultural legume crop, but powdery mildew disease caused by the biotrophic fungus regularly limits its annual yield. Assays to evaluate the efficacy of potential antifungal compounds or resistance genes for disease control require a simple fungal inoculation method that provides control over the initial inoculum concentration and enables uniform inoculum distribution within a leaf and across replicates as well as a method for the quantitative assessment of disease severity. Here, we present an easy spray inoculation method for the uniform distribution of a defined concentration of conidia on the leaves of pea plants and a semi-automated image analysis-based quantification of disease symptoms.

Whole genome resequencing data of four Indian mandarin genotypes: Extending our understanding of citrus genomics.

Mandarin orange ( Blanco) is the most common citrus fruit, covering nearly 42 % of the total citrus cultivation area in India. The main varieties of mandarin oranges cultivated in India include Nagpur Mandarin, Khasi Mandarin, Coorg Mandarin and Sikkim Mandarin. Globally, genomic data is being used to unravel the complexities and mysteries of citrus taxonomy.

Exploring the anti-aging effect of dextran and polyethylene glycol-coated cerium oxide nanoparticles in erythrocytes.

Oxidative stress generated during aging largely affects erythrocytes. Antioxidative therapies such as polyphenols and flavonoids face limitations like low bioavailability and reduced efficiency. Cerium oxide nanoparticles (CeONPs) can behave as antioxidative enzymes and thus have better efficiency.

CRISPR innovations in tissue engineering and gene editing.

The CRISPR/Cas9 system is a powerful tool for genome editing, utilizing the Cas9 nuclease and programmable single guide RNA (sgRNA). However, the Cas9 nuclease activity can be disabled by mutation, resulting in catalytically deactivated Cas9 (dCas9). By combining the customizable sgRNA with dCas9, researchers can inhibit specific gene expression (CRISPR interference, CRISPRi) or activate the expression of a target gene (CRISPR activation, CRISPRa).

Evidence for a sex-dependent effect modification in the association between IFN-λ DNA polymorphisms and expression of IFN-λ and interferon-stimulated genes in human PBMCs.

Human interferon (IFN) lambda (IFNL, IFN-L or IFN-λ) locus has several functional genetic variants but their role in regulating in vivo gene expression, and whether they associate with antiviral states in healthy individuals, is not clear. In this study, we recruited ∼550 healthy individuals belonging to both sexes, genotyped them for several IFNL genetic variants and measured, by qPCR, the expression of IFNL2/3, IFNL4 and four IFN-stimulated genes (ISGs) (MX1, OAS1, ISG15 and RSAD2) from their peripheral blood mononuclear cells (PBMC) both before and after stimulation with a viral mimic, poly I: C. We also measured secreted levels of several cytokines including IFN-λ1 and IFN-λ3 in poly I:C stimulated PBMCs.

SMCVdb: a database of experimental cellular toxicity information for drug candidate molecules.

Many drug discovery exercises fail because small molecules that are effective inhibitors of target proteins exhibit high cellular toxicity. Early and effective assessment of toxicity and pharmacokinetics is essential to accelerate the drug discovery process. Conventional methods for toxicity profiling, including in vitro and in vivo assays, are laborious and resource-intensive.
