Research areas




We would like to:
- investigate the molecular basis of phototropin signaling leading to chloroplast movements.
- elucidate the biological activity of well-known and putative Arabidopsis photolyases in terms of localization, chloroplast DNA maintenance and plant responses to abiotic stresses.
- examine how plants move chloroplasts in their natural environment.
