This morning, I was tasked with leading an e-discussion session for a colleague’s MSc. botany course in the UK, by Skype. It lasted around 1.5 hours, the students were fairly hardy. Topic was primary endosymbiosis, which is the process of engulfing a bacterium and incorporating it into the cell, a process most famous for having occurred at the origin of plants when their last common ancestor nommed a free-living cyanobacterium and kept it as a pet. This might seem like far out of my own fields of interest, but the detection of such things is a phylogenetic issue and thus falls under my purview, hence why the colleague asked me to do this.
The following is all the papers that we discussed. Reading them all should give you a very good idea on how primary endosymbioses happen, how they’re maintained, and how we detect them.
