Professor Yong Weon Seo's research lab focuses on plant molecular biology and stress adaptation, particularly in cereal crops like wheat. The lab investigates molecular mechanisms underlying responses to environmental stresses such as hypoxia, ionizing radiation, and oxidative stress, with a strong emphasis on gene regulation, post-translational modifications, and antioxidant defense systems. Key research directions include the identification and functional characterization of stress-responsive genes—such as Myb transcription factors and U-box E3 ligases—across the wheat genome, as well as the physiological and molecular impacts of low-dose gamma irradiation. The lab integrates genomics, transcriptomics, and functional genetics to understand stress signaling pathways in Triticeae species.

Oxygen deficiency is one of the major stresses to plants under waterlogging. A low‐oxygen‐signaling pathway is the most important mechanism for adaptation and survival under anaerobic conditions. To find genes related to the oxygen concentration in root environment in common wheat roots, we investigated the transcriptional expression in vitro for low‐oxygen treatment. Dramatic increases in the transcripts of a TaMyb1 ( Triticum aestivum Myb transcription factor 1) gene occurred under hypoxia. Pr
This suggests that exposure to ionizing radiation according to increase of exposure time has led to efficient induction of anthocyanin and antioxidant enzyme activities. This study indicates that reactive oxygen species (ROS) is eliminated by biosynthesis of anthocyanin and antioxidant enzymes. This study helps elucidate the biological effects of various durations of low-dose exposure to chronic gamma radiation in wheat plants.
U-box E3 ligase genes play specific roles in protein degradation by post-translational modification in plant signaling pathways, developmental stages, and stress responses; however, little is known about U-box E3 genes in wheat. We identified 213 U-box E3 genes in wheat based on U-box and other functional domains in their genome sequences. The U-box E3 genes were distributed among 21 chromosomes and most showed high sequence homology with homoeologous U-box E3 genes. Synteny analysis of wheat U-
This study provides some basic information regarding responses to gamma-irradiation, and provides valuable physiological and biological data on the effects of different gamma-irradiation dosages on Triticeae species.
