The primary cannabinoids cannabidiol (CBD) and tetrahydrocannabinol (THC), found in cannabis, are known to originate from genetic diversity, resulting in distinct characteristics. This study aimed to identify VOC markers to distinguish between higher CBD and THC cannabis cultivars under field conditions. Among the 58 VOCs, β-caryophyllene and α-humulene were primary VOCs across all cannabis cultivars.

Industrial waste and sewage deposit heavy metals into the soil, where they can remain for long periods. Although there are several methods to manage heavy metals in agricultural soil, microorganisms present a promising and effective solution for their detoxification. We isolated a rhizofungus, (GenBank Acc.

The fundamental question regarding the fractionation phenomenon is whether diffusion alone is responsible for it or whether an additional advection dynamic is involved. We studied the fractionation by diffusion of particles in spatially heterogeneous environments. By experimentally observing the time-sequential fractionation patterns of dye particles diffusing across a solid-solid interface of varying polyacrylamide gel densities, we found that the two-component diffusion model accurately captures the observed fractionation dynamics.

Article Synopsis
  • Atopic dermatitis (AD) is a long-lasting inflammatory skin condition linked to reactive oxygen species and inflammatory factors, with traditional medicine showing promise in treatment.
  • The study focused on the anti-AD potential of Salvia miltiorrhiza Bunge (SMB) by analyzing two cultivars, 'Dasan' and 'Kosan', for their secondary metabolites and pharmacological effects.
  • Results showed 'Dasan' had stronger antioxidant and anti-inflammatory properties, whereas 'Kosan' was more effective in reducing anti-AD gene expression; both cultivars demonstrated that SMB can help manage AD through various mechanisms involving its bioactive compounds.

Stress-resilient and highly nutritious legume crops can alleviate the burden of malnutrition and food security globally. Here, we focused on cowpea, a legume grain widely grown and consumed in regions at a high risk of micronutrient deficiencies, and we discussed the past and present research on carotenoid biosynthesis, highlighting different knowledge gaps and prospects for increasing this micronutrient in various edible parts of the crop. The literature survey revealed that, although carotenoids are important micronutrients for human health and nutrition, like in many other pulses, the potential of carotenoid biofortification in cowpea is still underexploited.

Article Synopsis
  • The study examined how harvest time affects the phytochemical composition of four plants: Korean mint, lemon balm, opal basil, and sage, focusing on compounds like rosmarinic acid (RA) and volatile organic compounds (VOCs).
  • Despite all plants having RA as a major component, its levels increased differently depending on the species and whether they flowered, with flowering plants showing a rapid increase during the reproductive stage.
  • The research found that VOCs varied by plant type, with specific fragrance compounds identified, and noted that total VOCs peaked 60 days after transplanting.

is a perennial tuberous root in the Asclepiadaceae family that has long been used medicinally. Although is distinct in origin and content from , a genus of the same species, it is difficult for the public to recognize because the ripe fruit and root are remarkably similar. In this study, images were collected to categorize and , which were then processed and input into a deep-learning classification model to corroborate the results.

Korean ginseng is a source of functional foods and medicines; however, its productivity is hindered by abiotic stress factors, such as light. This study investigated the impacts of darkness and different light wavelengths on the metabolomics and anti-cancer activity of ginseng extracts. Hydroponically-grown Korean ginseng was shifted to a light-emitting diodes (LEDs) chamber for blue-LED and darkness treatments, while white fluorescent (FL) light treatment was the control.

Rapid industrialization and global warming have threatened the plants with multiple abiotic stresses, such as heavy metals and drought stress. For crop cultivation, the conventional approach of cleaning the soils by excavation is very costly and not feasible for large scale. Establishing toxin-free and drought-resistant crops is a major challenge in the environment under natural and anthropogenic pressure.

The development and promotion of biofortified foods plants are a sustainable strategy for supplying essential micronutrients for human health and nutrition. We set out to identify quantitative trait loci (QTL) associated with carotenoid content in cowpea sprouts. The contents of carotenoids, including lutein, zeaxanthin, and β-carotene in sprouts of 125 accessions were quantified via high-performance liquid chromatography.

Gray mold disease is one of the most frequently occurring diseases in strawberries. Given that it spreads rapidly, rapid countermeasures are necessary through the development of early diagnosis technology. In this study, hyperspectral images of strawberry leaves that were inoculated with gray mold fungus to cause disease were taken; these images were classified into healthy and infected areas as seen by the naked eye.

The presence of nutritional and health-benefiting compounds has increased awareness of orphan leafy vegetables such as (CG), whose phytochemicals vary among accessions and organs during growth. This study investigated the polyphenol accumulation and antioxidant activities (AOA) of eight CG accessions from the vegetative stage to the seed set stage. Plants were separated into leaves and stem (LS), flowers, and silique organs, and extracts were analyzed for total phenolic content (TPC), total flavonoid content (TFC), rutin and astragalin content, and AOA using 2,2-diphenyl-1-picrylhydrazyl-hydrate (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS).
