Cell signaling in Chlamydomonas

Summary

Our group has been pioneer in the study of the target of rapamycin (TOR) signaling pathway and autophagy, a degradative process conserved in all eukaryotes required for the cellular adaptation to stress, in the model unicellular green alga Chlamydomonas reinhardtii. The main goal of our research is to understand how stress, in particular redox unbalance, regulates autophagy in photosynthetic eukaryotes using Chlamydomonas as model system. We have unraveled the molecular mechanisms underlying the redox regulation of some key components of the autophagic machinery in Chlamydomonas. Future research lines will investigate the complex regulation of autophagy by environmental stress and the role of the TOR signaling pathway in the control of this degradative process.
