研究室紹介
Professor Hyunjun Lee's research lab focuses on plant developmental biology, particularly the molecular mechanisms regulating flowering time and cellular reprogramming in plants. The lab investigates how genetic and environmental cues—such as temperature and photoperiod—control floral transition, using natural Arabidopsis accessions as models. Additionally, the lab explores the potential of plant cells to reprogram into diverse organ types, recently demonstrating the regeneration of stolons and tubers from potato leaf callus through Agrobacterium-mediated signaling. These studies aim to uncover fundamental principles of plant pluripotency and organogenesis with applications in crop improvement and biotechnology.

3Flowering is a critical trait for reproduction and survival in plants and is influenced by both temperature and photoperiod. Here, we explored the molecular basis of temperature- and photoperiod-insensitive flowering in the Arabidopsis natural accession IP-Svi-0. We identified genetic variations underlying the early flowering of IP-Svi-0 using whole-genome and RNA sequencing and verified them by generating transgenic plants that complemented or silenced the responsible genes. The complete insens
Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves. Despite this pluripotency, organs regenerated from leaf callus have predominantly been confined to conventional shoots and roots, leaving the potential to regenerate other specialized organs unknown. In this study, we identified that stolons can be regenerated from potato leaf callus. Furthermore, we demonstrate that Agrobacterium tumefaciens stimulation efficiently induces stolon regenerat
