"They propose that early protoeukaryotes were predators, relying on bacterial prey. These bacteria, in response to predation, produced toxins as a defense mechanism. Over time, these bacteria were domesticated to serve as mitochondria within eukaryotic cells, and their toxins evolved into apoptotic factors. "

'Both genomes had been analysed before, but the fragmented assemblies had scaffold sizes comparable to the length of long reads prior to assembly. Our new assemblies illustrate how long-read technologies allow for a much better representation of species genomes. We are now able to conduct more accurate downstream assays based on more complete gene and transposable element predictions.'

Hello everyone!
Iโm an associate prof at Virginia Tech studying viral diversity. Lately my group has been focusing on giant viruses, but we are also interested in other protist viruses, and the role of viral endogenization in host genome evolution.

Fight not flight: parasites drive the bacterial evolution of resistance, not avoidance
In the face of ubiquitous threats from parasites, hosts often evolve strategies to resist infection or to altogether avoid contact with parasites. At the microbial scale, bacteria frequently encounter viral parasites, bacteriophages.bioRxiv
'Our findings demonstrate that developmental bias in fly wings predicts evolvability and macroevolutionary trajectories on a much greater scale than previously appreciated but also suggest that causal explanations for such alignments may go beyond simple constraint hypotheses.'
