Abstract Consumers are increasingly demanding natural colorants that are safe and offer health benefits. In addition to their ornamental characteristics, Kanzan cherry (KC) blossoms present a promising source of red-hued natural colorants and functional bioactive substances. This research utilized distilled water to extract KC petals (KCP) and their ground powders (KCPP) under varying temperatures (30°C–90°C) and times (30–180 min). The total monomeric anthocyanins (TMAC) and total phenolics (TPC) in the extracts were evaluated via the pH differential and Folin–Ciocalteu methods. Antioxidant capacities were assessed by DPPH free radical scavenging ability and reducing power. Results indicated that… More >

Abstract Houttuynia cordata, a characteristic edible and medicinal plant in southwestern China, is prone to absorbing lead (Pb²⁺). Excessive consumption may lead to Pb²⁺ accumulation in the human body, which has been linked to serious health risks such as neurotoxicity, kidney damage, anemia, and developmental disorders, particularly in children. Therefore, the development of molecular markers associated with Pb²⁺ uptake and the investigation of the plant’s physiological responses to Pb²⁺ pollution are of great significance. In this study, 72 H. cordata germplasms were evaluated for Pb²⁺ accumulation after exogenous Pb²⁺ treatment. A significant variation in Pb²⁺ content was observed among the germplasms, indicating… More >

Abstract Pimenta dioica is a tropical Caribbean tree belonging to the family Myrtaceae, widely used in various human activities, including perfume production, food flavoring, natural pesticides, and medicine. This study aimed to explore the chemical composition of Pimenta dioica flower essential oil obtained via hydrodistillation using GC-MS analysis. Additionally, the oil’s tyrosinase inhibitory activity was investigated. The effectiveness of the oil’s major constituents in binding to tyrosinase was also evaluated through molecular docking simulations. GC-MS analysis identified fifteen compounds, with eugenol (70.59%) as the major component, followed by β-myrcene (10.54%), limonene (8.55%), β-ocimene (4.92%), α-phellandrene (1.39%), and linalool… More >

Abstract Peach gum polysaccharide (PGP), a readily available natural polysaccharide, boasts substantial potential across diverse applications, yet its practical utility is severely limited by its vulnerability to bacterial growth and limited antioxidant activity. Herein, we introduced a simple and effective method to enhance the antibacterial and antioxidant properties of PGP by conjugating it with salicylic acid (SA). Cytotoxicity evaluation results confirmed that the resulting PGP-SA retains the excellent biocompatibility of PGP. Notably, PGP-SA demonstrates outstanding antibacterial activity against both Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria, outperforming non-modified PGP. Its antibacterial mechanism is hypothesized to stem from… More > Graphic Abstract

Abstract Wheat stripe rust, a devastating disease caused by the fungal pathogen Puccinia striiformis f. sp. tritici (Pst), poses a significant threat to global wheat production. Growing resistant cultivars is a crucial strategy for wheat stripe rust management. However, the underlying molecular mechanisms of wheat resistance to Pst remain incompletely understood. To unravel these mechanisms, we employed high-throughput RNA sequencing (RNA-Seq) to analyze the transcriptome of the resistant wheat cultivar Mianmai 46 (MM46) at different time points (24, 48, and 96 h) post-inoculation with the Pst race CYR33. The analysis revealed that Pst infection significantly altered the expression of genes… More >

Abstract The production of crops is badly affected by climate change globally. Mitigation of adverse effects of climate change is in need of time through different management practices such as developing tolerant genetic resources, hormonal applications to boost defense systems, nanoparticles, and balanced fertilization. The nano-hormonal synergy had the potential to mitigate the adverse effects of climate change by modulation of morpho-physiological and biochemical activities. Plant growth, yield, and quality can be enhanced with the supplementation of nano-hormonal interactions. Therefore, the current study explores the synergy between nanoparticles and phytohormonal use. The nanoparticles, even in low… More >

Abstract The trends of consuming or using eco-friendly, biodegradable products due to the change in the lifestyle of the people have led to the exploration of new sources from plants or animals. Seed mucilage (SeM) is an underexplored component of plants that can be brought into play to deal with such problems. Mucilage, a viscous polysaccharide that can be obtained when seeds like chia, flax, garden cress, and tomato get hydrated and form a slimy, gel-like substance around the seed coat, can be utilized due to its unique characteristics. It has been used in developing many… More >

Abstract This study aims to determine the phytochemical composition and antioxidant activity (AA) of different plant parts (bulbs, stalk, leaves and flowers) of wild rosy garlic (Allium roseum) from Montenegro. The flower exhibited the highest concentration of total phenols (55.7 GAE/g d.e.), followed by the leaf (25.6 mg GAE/g d.e.). The leaf displayed the highest concentration of total flavonoids (41.48 mg RE/g d.e.), followed by the flower (36.26 mg RE/g d.e.) and top part of the stalk (26.80 mg RE/g d.e.). The AA of different parts of A. roseum after 60 min of incubation decreased in the following… More >

Abstract Tomato is an economically important crop that is susceptible to biotic and abiotic stresses, situations that negatively affect the crop cycle. Biotic stress is caused by phytopathogens such as Fusarium oxysporum f. sp. lycopersici (FOL), responsible for vascular wilt, a disease that causes economic losses of up to 100% in crops of interest. Nanomaterials represent an area of opportunity for pathogen control through stimulations that modify the plant development program, achieving greater adaptation and tolerance to stress. The aim of this study was to evaluate the antimicrobial capacity of the nanoparticles and the concentrations used in tomato… More >
