Phototaxis is one of the main categories of motility regulation by microorganisms. Arguably, it is particularly important for motile micro algae, due to their photosynthetic activity. One of the organisms where it has been studied the most is our beloved micro alga Chlamydomonas reinhardtii. Currently, we have a pretty good idea of the mechanism leading the cells to reorient towards/away from the light, but not much is known about what happens after they’ve reoriented…. In our recent paper we start looking into this, with surprising results.
We had the great pleasure to host for two months Julia Dolger, PhD student from the group of Anders Andersen and Thomas Kiorboe at the Technical University of Denmark. She’s been working very hard during her short stay here on a joint project looking at microbial predator/prey systems, and we had lots of interesting discussions! Good luck to her for the final part of her PhD and let’s keep in touch!
