Chin-Mei Lee Assistant Professor
Ph.D., Michigan State University, USA
Specialty: Plant Circadian Clock, Plant Abiotic Stress, Protein Ubiquitination
Laboratory: Life Science Building R1150
Current Research Interests
1. The molecular mechanism underlying plant circadian clock
2. Plant circadian clock regulated daily and seasonal rhythmic pathways
The circadian clock is an approximately 24-hour endogenous timekeeper to help organisms respond properly to the rhythmic environmental changes due to the Earth rotation. In plant, circadian clock not only times daily rhythmic physiological processes (photosynthesis, carbohydrate metabolism, biosynthesis of phytohormone and secondary metabolites etc.) but also measures seasonal time to allocate energy for growth, development and dormancy. In addition, it helps plants to anticipate external biotic and abiotic stimuli for stress resilience and their survival. Some knowledge gained from circadian clock studies have been translated to agriculture practices to control flowering time, boost crop yield, and enhance stress resistances and herbicide effectiveness. However, circadian clock-regulated biological processes and their mechanism remain to be explored. My research will focus on the following directions to study the mechanism underlying plant circadian clock and its downstream biological pathways in hope of translating to agriculture.
1. Understanding how do rhythmic light and temperature signals entrain and maintain plant circadian clock
2. Deciphering how does plant circadian clock modulate abiotic stress
3. Investigating how does plant circadian clock regulate seasonal growth and development
The positions are available for undergraduate interns, graduate students and postdocs. If you are interested in studying circadian clock or abiotic stress, welcome to join us!!
