Molecular Genetics and Physiology

Our research aims to elucidate the mechanisms of genome maintenance in nuclei and organelles, stress response, and symbiosis in bacteria, plants, and animals under global climate change. Our broad objectives are to understand the specific regulatory events that control these processes, as well as the more fundamental aspects of DNA repair, transcriptional activation, and post-transcriptional modification.

Research Overview

We are now heavily focused on the following subjects: 1) molecular and physiological responses to environmental stresses (increasing and decreasing temperatures, UV radiation, salt, microgravity, and space radiation); 2) genome wide analysis of naturally occurring intra-species variation in physiology, environmental response, and plant-microbe interaction; and 3) applied biology for the sustenance of crop yields against climate change, through the use of the model organisms, Arabidopsis, Oryza sativa, Lotus japonicas, and the nematode C. elegans.
