A tale of two nucleobionts: Holospora obtusa and Holospora undulata
I got really intrigued about the paramecium endonuclear symbionts. So this will be the subject of our first research challenge in class. I got really intrigued because these bacteria (Holospora) don't just happen to end up in the macro or micronucleus, they possess specific mechanisms to discriminate and enter these nuclei and they also bind to chromatin. They even dramatically change their morphology to perform this feat. This is fascinating because I thought that perhaps viruses were the only creatures which possess designs to invade nuclei. So what could these nucleobionts be doing? According to a speculative theory developed by my colleague Todd Wood these creatures might be doing something very significant. But you will have to find his paper to find out more about this (AGEing). I cannot give away anymore hints now, but stayed tuned to this blog for more hints.
