Integrated Assessment of Pollen Substitute Diets in Honey Bees Based on Transcriptional Responses, Immune-Derived Predicted Biological Age, and Survival

Heat events and nutritional stress threaten honey bee health, but how pollen substitute formulation shapes responses to acute heat remains unclear. Newly emerged Apis mellifera workers received three pollen substitute diets or two beebread-based reference diets for five days befo...

Comparative immunogenomics of Suidae reveals lineage-specific immune gene disruption and positive selection

Understanding the evolutionary dynamics of immune-related (IR) genes among closely related species provides key insights into lineage-specific adaptations to pathogens. The family Suidae is a powerful model for investigating immune gene evolution owing to its broad ecological div...

Genome-Edited Nuruk-Derived Yeast for Enhancing Quality and Flavor of Fermented Foods

Abstract While esters are known to provide fruity and floral characteristics, their production is often insufficient to meet consumer preferences. In this study, Saccharomyces cerevisiae N9 isolated from Korean nuruk (fermentation starter) was engineered using Cas9-based genome e...

Temporal Variability of Particulate Matter Across Garlic Cultivation Periods: A Two-Year Monitoring Study in a Small-Scale Garlic Field in Rural South Korea

Ambient particulate matter (PM) concentrations at agricultural monitoring sites may reflect field activities, meteorological conditions, regional background pollution, long-range transport, and secondary aerosol formation. This study characterized temporal variation in PM10 and P...

Antiviral activity of Cirsium japonicum var. spinossimum extract and its flavonoid cirsimaritin against human coronavirus OC43

Coronaviruses cause a wide range of diseases, ranging from the common cold to severe illnesses such as COVID-19. Although vaccines and therapeutics against COVID-19 have been developed, recent reports have documented the emergence of viral variants with reduced susceptibility to...

UAV-based YOLOv11 system for automated detection and counting of male hemp plants bearing staminate flowers

Abstract The flowering stage is a crucial phenological phase in hemp production, determining the maturity group of grain and fiber varieties, yield potential, and optimal harvest timing. Enabling early-stage detection of flowering male plants and distinguishing them from non-flow...

Weather-based prediction of black locust (Robinia pseudoacacia L.) honey yield and quality: a reproducible computational system with operational deployment

Black locust (Robinia pseudoacacia L.; marketed as “acacia”) honey production in South Korea—accounting for over 70% of national honey output—has been increasingly affected by weather-driven disturbances, resulting in substantial production declines, notably in 2018 and 2020 ( Ki...

Iron-responsive transcription factor SreA regulates calcium homeostasis independently of calcineurin–Crz1 pathway in Fusarium graminearum

ABSTRACT Calcium is an abundant intracellular ion that is intricately involved in various cellular processes. The precise regulation of calcium homeostasis is critical for fungal physiology. In fungi, calcium signaling is primarily mediated by the calmodulin–calcineurin pathway,...

Fish Assemblages Distinguish Eco-Friendly from Conventional Rice Paddies Through Abundance and Biomass Rather than Diversity

Although rice paddies are agricultural land, they also serve as artificial wetlands that deliver essential ecosystem services. Yet how farming systems affect their fish communities—and which metrics best capture those effects—remains poorly quantified in Asia. We compared fish as...

Identification of Early Stage Physiological Indicators for Summer Heat Resilience in Kimchi Cabbage (Brassica rapa L. ssp. pekinensis) via Integrated GWAS and Machine Learning

The production of Kimchi cabbage (Brassica rapa L. ssp. pekinensis) is increasingly threatened by concurrent heat and drought stress, which induce physiological disorders and severe heading failure. In this study, we implemented a dual-environment screening strategy to identify r...
