The main research areas
Optogenetics, designed by using photoreceptors, is a noninvasive method to control either gene expression or cellular functions by light exposure. Optogenetic approaches have numerous advantages over conventional techniques with adjustable activity; high spatial precision and high temporal resolution. Our group is dedicated to advancing new optogenetic technologies by engineering systems with precise and tailored kinetics.
Pollen tube growth and stomatal movement play critical roles in plant growth, development, and overall physiological function. In our previous research, ACR1 2.0 were effectively employed to regulate pollen tube growth and control stomatal movement with precision. We are committed to utilizing diverse optogenetic tools to orchestrate various signals within plants, aiming to precisely regulate their growth and development.
In response to pathogen attacks, plants trigger a complex defense signaling network including [Ca2+]cyt increases, plasma membrane depolarization, ROS signaling, and phytohormone alterations. How individual of these signaling elements are channeled into specific physiological outcomes is poorly understood. Our group are applying optogenetic tools to targeted manipulation of specific signaling element and investigating their role in plant immune responses.
