Research

  • Adaptation of cyanobacteria and plant to environmental stresses
  • Polyamine roles in cyanobacteria to environmental stresses
  • Regulation of photosynthetic systems in cyanobacteria
  • Biotechnological and Biomedical applications from cyanobacteria

In my group, we have been focused on the function and regulation in cyanobacterial adaptation under environment stresses. In one hand, the polyamine biosynthesis against UV-radiations has been working. Strikingly, we have found the different responses of polyamine contents under various single wavelengths of UV exposures (A, B and C). As the polyamine mechanism and function are still unclear, particular in cyanobacteria. We are trying as well to figure out the correlation between polyamines and photosynthetic systems using genetic and bioinformatics approaches. Our goal so far is to understand polyamine function and regulation on stress response and adaptation and to develop these studies in field of biotechnological and biomedical applications; such as to improve the tolerance on light stresses by genetic manipulation of either commercial or crop plants in the future.
