Hwiseong Jeon specialises in plant immunity, focusing on lignin barriers formed in response to bacterial and fungal pathogens. His research aims to verify lignin as a key component of fungal-induced papillae and examine lignin barriers associated with hypersensitive response (HR) cell death. Building on the known role of CASP membrane proteins in root lignin deposition, he seeks to determine the localisation of immune-related CASPs during plant defence. Additionally, Hwiseong aims to demonstrate that autophagy mediates lignin barrier formation via intracellular transport processes.
