Unicellular Green Alga

The unicellular green alga Chlamydomonas eugamatos is surrounded by a glycoproteinaceous cell wall. Using the quick-freeze deep-etch technique, we analyse the organization of the wall layers in situ, and delineate the structure of the outermost crystalline layer (W6). We also show the structure of the protein monomers, and propose a model for their organization in the crystal that is similar to that deduced for the related Chlorogonium elongatum crystal by image reconstruction analysis. We also show that the C. eugamatos crystal is highly similar to the flagellar collar of Chlamydomonas reinhardtii.

Clinical Problems

AbstractWe have recently proposed a novel strategy named photosynthetic tissue engineering to overcome clinical problems due to hypoxia. The idea is based on transgenic photoautotrophic microorganisms that produce oxygen and at the same time secrete functional recombinant proteins into tissues. In particular, the unicellular green alga Chlamydomonas reinhardtii has successfully been used to boost the regenerative potential of several biomedical devices, such as dermal scaffolds and surgical sutures.
