Professor Youngryel Ryu group from Department of Landscape Architecture and Rural Systems Engineering at SNU has mapped carbon stock and growth of individual street trees using LiDAR-camera fusion-basd mobile mapping system and published this work in Remote Sensing of Environment.Urban areas remain one of the least quantified ecosystems in terms of carbon sequestration capacity, primarily due to the limitations of tra...

Professor Moon-Seong Kang’s research team from SNU CALS has developed a Web-based Rainfall Erosivity Calculation (WREC) decision support tool, which enables rapid and accurate estimation of rainfall erosivity based on the resolution of meteorological data available to users. Soil erosion is a significant global problem that has far-reaching effects on agricultural productivity, environmental health, and eco...

o This study investigates the genetic mechanisms by which the probiotic Bacillus subtilis regulates nitric oxide (NO) metabolism and its effects on host aging and neurodegeneration.o A microbial genome-wide association study (mGWAS) was conducted using 1,654 gene deletion mutants of B. subtilis to identify strains that influence lifespan, amyloid-beta accumulation, and behavioral phenotypes in C. elegans. Two genes, nosA (N...

□ o Methane produced in the rumen—the main digestive organ of ruminants—is recognized as a major contributor to greenhouse gas emissions from global livestock industries. While chemical additives and antibiotic-based inhibitors have been previously investigated, their limited sustainability and adverse effects on the gut microbiota present significant challenges.o The research team identified Komagataeibacter in...

Prof. Tae-Jin Yang’s team at Seoul National University assembled a high-quality genome of Glycyrrhiza uralensis and revealed the hybrid origin and evolutionary history of licorice species through genome-wide analysis of 29 individuals. The study identified three hybrid groups bridging G. uralensis and G. glabra, offering key insights into genetic variability and conservation of this medicinally and economically import...

Atopic dermatitis (AD) is a globally prevalent chronic inflammatory skin disorder. Its pathogenesis remains incompletely understood, resulting in considerable therapeutic challenges. Recent studies have highlighted the significance of the interaction between AD and gut microbiome. In this study, we investigated the effects of probiotic-derived extracellular vesicles on AD. Initially, we isolated and characterized extr...

Planting density and leaf angle are important factors related to rice growth and yield through interplant competition. Despite the necessity of understanding the dynamics of interplant competition according to planting density and leaf angle, detailed physiological changes throughout the growth cycle remain less clear due to the requirement for field surveys that are labor-intensive and time-consuming. Sun-induced chlorophy...

Recognizing the challenges in using botanicals as sustainable pest control agents due to compositional variation, this study addresses the limitations of traditional component-based approaches such as Hewlett and Plackett or Wadley’s models. Based on the assumption of noninteractivity among constituents, these models often fail to predict outcomes accurately due to dynamic intermolecular interactions. We introdu...

Professor Choi’s research team at SNU has identified the Vibrio vulnificus transcription factors at a genome-wide scale and characterized their functions comprehensively, proposing novel targets to control the pathogen. For successful infection, the life-threatening pathogen Vibrio vulnificus elaborately regulates the expression of survival and virulence genes using various transcription factors (TFs). In ...

Prof. Tae-Jin Yang’s team from Seoul National University established a foundation for a molecular breeding in Panax ginseng by developing high-throughput SNP chip and suggested diverse applications for its use, with findings published in Horticulture Research in December, 2024.
